Acid rain emerged as a salient political issue in Ontario during the late 1970s in the wake of multiple scientific studies and media reports of its damaging effects on emblematic tourist areas in the province. In the popular “cottage country” Muskoka and Halliburton regions near Toronto, the rapid deterioration of the area’s many lakes had alarmed local property owners and businesses, and the studies and reports pointed to the culprits—notably Ontario’s nickel-copper ore smelting and power-generation industries. Politicians learned they would sidestep the problem at their peril during the summer of 1978, when a rescinded control order on the International Nickel Company of Canada (Inco), the province’s largest emitter of acid rain precursors, unleashed a public backlash raising the prospect of a nonconfidence motion against the government and leading to the replacement of the newly appointed environmental minister. With acid rain now on the policymaking agenda, a succession of events occurred that were significant enough for several academic observers to assert that Canada had at the time entered a new era of environmental mobilization.Footnote 1
The case of acid rain in Ontario has been used in the public policy literature as an example of the second “wave” or “generation” of environmental policymaking in Canada. As with environmental policy in the United States, the prominent scholarly understanding is that an environmental movement in the late 1960s brought about substantial changes in the way that environmental issues are governed.Footnote 2 In Canada, a number of environmental policy developments—most notably acid rain precursors reductions and an elimination of stratospheric ozone-depleting substances—during the 1980s have been interpreted as an ecological reawakening of sorts.Footnote 3 Yet an examination of the history of air pollution governance in both Canada and the United States suggests that the acid rain case was a continuation of a persistent pattern occurring in North America since the 1910s or earlier. This observation is itself not novel, as several historical studies have identified aggressive air pollution abatement efforts in urban areas during the course of the entire twentieth century.Footnote 4 However, the specific regularities and discontinuities in air pollution governance have been rarely spelled out and, even then, incompletely. Those that have examined long-term trends have underscored the role of locally oriented propertied interests in lobbying for and formulating clear air policy in order to facilitate continued economic growth and the associated increase in land values.Footnote 5 Generally, albeit with exceptions, such propertied interests have taken the specific form of influential local elites. These studies and others have also identified the centrality of ecological modernization to this process since the use of technology rather than changes in natural resource processing and consumption enable economic activity to avoid substantial disruption.Footnote 6
Our analysis in this article seeks to enrich the empirical record of the history of North American air pollution governance by reaffirming the role of locally oriented (and primarily elite) propertied interests and also the form this policy takes. In doing so, we underscore one manner in which policymaking had ostensibly changed with the acid rain case; namely, sufficiently inexpensive and reliable technology existed for a solution that satisfied all parties. Thus, we argue that what appeared as a new era of environmental policymaking was, at least partly, the result of the implementation of technology (i.e., ecological modernization), enabling the resolution of the problem in a way consistent with the unfettered continuation of existing economic activity. While this has already been shown to be true in the case of the global replacement of ozone-depleting chlorofluorocarbons with other chemicals, we outline a similar process with the abatement of acid rain precursors.Footnote 7
To show that elite propertied interests were central to agenda setting and policy formulation in the acid rain case, we illustrate the importance of the region’s two large urban newspapers and a broad coalition of actors in which elite property played a dominant role. These newspapers and the Canadian Coalition on Acid Rain (CCAR) lobbied for specific abatement policy measures, commissioned and reported public opinion polls, gathered and framed information about the economic costs of acid rain, and negotiated directly with polluters about government assistance for smelter modernization. To illustrate the importance of technology in clean air policy, we take advantage of the fact that acid rain precursor reductions in Ontario occurred in two rounds. Initially, the availability of inexpensive and reliable technology for smelter modernization was not apparent and relatively minimal reductions were agreed to by industry. However, once the pro-reduction coalition of actors was able to establish the existence of this technology, it became possible for these actors to negotiate a policy with polluters and provincial officials that would reduce emissions to the levels sought at the beginning of the controversy. The province’s electricity utility, similarly, was able to secure a cheaper and more reliable solution to coal emissions between the two rounds of reductions, enabling further reductions. Below we present the case of acid rain policy and politics in Ontario, focusing on the competition between heavy industry and property, and the role of technology in facilitating a resolution to the problem. First, however, we provide a theoretical overview to frame our account of the facts.
Propertied Interests and North American Air Pollution Politics
Our focus on the role of propertied economic interests in air pollution abatement is consistent with findings of other recent historical studies of North American air pollution politics. In Smelter Smoke in North America, John D. Wirth provides an account of the Trail smelter dispute, which pitted farmers and local businessmen in a small northern Washington town against a smelter in southern British Columbia during the 1920s and 1930s. Ted Moore examines the role of the Salt Lake Women’s Chamber of Commerce on urban air pollution policy during World War II. He shows that this local growth coalition sought to improve the city’s air quality by pursuing planning policies leading to more local control and diversification of industrial operations. Similarly, Owen Temby illustrates how Toronto’s business community of the 1950s conducted research on the economic costs of the city’s pollution problem and proposed a regulatory program to the provincial legislature. Their efforts paid off in the form of a larger-staffed and better-equipped air pollution control department and expanded municipal authority, enshrined in Ontario’s 1958 Air Pollution Control Act, to regulate pollution sources within the city’s borders.Footnote 8
The findings of these studies about the centrality of locally oriented propertied interests in clean air policy reflect observations expressed and accounted for by urban regime theory, which examines the behavior and composition of governing coalitions in urban planning.Footnote 9 Urban regime theorist Harvey Molotch argues that in any circumscribed locale, the primary imperative for governments and the coalitions they rely on to govern is growth.Footnote 10 Furthermore “the desire for growth provides the key operative motivation toward consensus for members of politically mobilized local elites, however split they may be on other issues.”Footnote 11 To maintain the city as a “growth machine,” urban policy tends to aim at cultivating a favorable business climate, with other values (such as poverty eradication and civil rights) as lower priorities.Footnote 12 As Clyde W. Barrow states, “The taxes and fees that support public infrastructure, public education, and state-regulated employee mandates should all be regarded as transaction costs” in pursuance of growth.Footnote 13
In the political process of planning for growth, urban regime theorists argue for the primacy of planning networks consisting of local propertied elites—local growth coalitions, chambers of commerce, media firms, hotels, tourism associations, and so on.Footnote 14 Yet Molotch considers a newspaper “the most important example of a business which has its interest anchored in the aggregate growth of the locality.”Footnote 15 Rather than newspapers benefiting from and seeking the expansion of any particular source of local economic growth (e.g., heavy industry or tourism), they tend to be focused on the general expansion of the market for their product. Molotch observes that, for this reason, “Competing interests often regard the publisher or editor as a general community leader, as an ombudsman and arbiter of internal bickering and, at times, as an enlightened third party who can restrain the short-term profiteers in the interest of more stable, long-term, and properly planned growth.”Footnote 16 A local newspaper can thus be understood as a generalized expression of the locale’s propertied interests. Notably, George Gonzalez’s analysis of Los Angeles smog policy and Temby’s of Toronto’s smog politics both highlight the significance of the regions’ newspapers as propertied interests developing and promoting clean air policy.Footnote 17
Gonzalez’s historical study of American air pollution policy in The Politics of Air Pollution identifies propertied interests (especially urban elites) as the source of the political incentive to address urban smog. Arguing that “clean air policies are functional to the operation of the market and to the realization of profit,” Gonzalez provides an account of the importance of elite propertied interests in the smog policy of Los Angeles in the 1940s and 1950s.Footnote 18 He shows that an array of local economic interests that profit from the use and sale of land were instrumental in developing clean air policy, negotiating with polluting industries, and pressuring elected officials for action. By comparing this case to the efforts of local Chicago elites to address smog in the late 1800s and early 1900s, Gonzalez further underscores the importance of the availability of technology to air pollution policy. Whereas a range of technologies existed, enabling Los Angeles to take substantive (albeit partial) measures to limit smog, such was not the case in Chicago fifty years earlier. There propertied elites, benefiting from the local growth facilitated by the polluting firms not sharing a local orientation, acquiesced on emissions controls rather than provide an economic climate unfavorable for the firms. Similarly, in a recent study on Canadian automobile emissions regulations during the 1970s, Dimitry Anastakis points to the specific properties of abatement technologies available at the time for an explanation of Canada’s laxer tailpipe standards in relation to the United States.Footnote 19 Thus, a growing literature on air pollution politics suggests that the availability of control technology and the imperatives of local growth have historically been among the most important determinants of clean air policy.
In Ontario during the late 1970s and 1980s, the issue of acid rain similarly aroused concern among Ontario’s propertied interests, in this case those implicated in the markets for tourism and expensive cottages on the outskirts of Toronto. Throughout the period during which acid rain was a salient political issue, it was frequently articulated by Toronto’s newspapers and other growth-oriented organizations as a threat to the city’s and the surrounding area’s growth and economic well-being. In what follows, we provide an overview of Ontario’s propertied and industrial actors participating in the policy process over sulfur dioxide emissions. We then discuss each of the two rounds of sulfur dioxide reductions undertaken by Ontario’s polluters and the related actions of the provincial and federal governments. There we explicate the role of the province’s propertied interests throughout the acid rain abatement policy process and also the catalytic role of technology in enabling policy change.
Our analysis relies mainly on information retrieved from public archives, written memoirs of participants in the policy process, and also from other scholarly historical accounts of the topic. Its claim about the role and importance of property and technology shifts the focus compared to interpretations of the acid rain case previously offered by other scholars. One notable example is Kathryn Harrison’s book, Passing the Buck, which is concerned with spelling out federal-provincial dynamics in environmental policy.Footnote 20 Harrison argues that the outcome of the acid rain case can best be understood as an example of harmonious federal-provincial policymaking rather than, for example, a turf battle between the two. An alternative account is needed because Harrison’s analysis does not adequately assess the source of the political incentive to address the problem in the first place. While a focus on federal-provincial dynamics might yield useful insights about the way these two governments interact, it does not tell us how acid rain policymaking occurred in Ontario during the period we cover in this article. Similarly, Douglas Macdonald’s Ph.D. thesis provides an account of negotiations between the Ontario government and the province’s major polluters from 1982 through 1985. Although his study is effective within its scope, Macdonald admits that his exclusion of “the world of Ontario acid rain politics” leaves him unable to explain policy change during the period examined.Footnote 21
Despite our overtly political focus, we nevertheless avoid explanatory recourse to contextual factors such as election results or the partisan identification of the government in power.Footnote 22 As is evident from our account, the acid rain issue was shot through with rhetorical posturing by elected officials. Any trustworthy narrative of the events must take into consideration their need to appear responsive to this highly symbolic and salient public problem. But it would be a mistake to conclude on this basis that an explanation of the policy response should include an analysis of the effect of electoral outcomes. Apart from the analytical desirability of parsimonious theoretical accounts not resorting to the inclusion of ad-hoc factors, there is substantial evidence from other studies of growth machine politics that the partisan identification of elected officials has little influence on policies formulated by locally oriented pro-growth elites.Footnote 23
Economic Interests and Acid Rain Politics
Consistent with prior studies of air pollution politics, among the principal actors in the acid rain policy process were (1) propertied economic actors interested in promoting and facilitating the growth of the locale and with ecological preservation as a condition of this growth, and (2) industrial actors concerned with maintaining low operating costs and with the sale of their products on the broader (i.e., not necessarily local) commodity market. While their shared objective in economic growth was crucial in reaching an eventual “ecological modernization” compromise solution, the scale on which they sought the implementation of this approach represented the conditions for a political conflict over acid rain precursors. Here, in turn, we present each of these two classes of economic interest.
Property
Numerous organizations representing the interests of local growth and property ownership sought provincial action against acid rain in the late 1970s to the mid-1980s, including the Huntsville Chamber of Commerce and the Federation of Ontario Cottagers’ Associations (FOCA). Yet the most influential were the CCAR and Toronto’s print media, which together pressured the Ontario government for acid rain relief through the regulation of Inco, Ontario Hydro, and the other metal-processing facilities.Footnote 24 The CCAR was an umbrella organization interested in addressing acid rain through public campaigning and private negotiations with governments and polluters. It grew from twenty-five members at the time of its March 1981 launch to fifty-six member groups, representing a membership in excess of two million Canadians at the time of its dissolution in 1991.Footnote 25 Reflecting on its importance, Globe and Mail (Globe) acid rain reporter Michael Keating says that “the most sustained and effective criticism of government and business came from the Canadian Coalition on Acid Rain, which maintained constant pressure for acid gas reductions by constantly pressing the media to cover various aspects of the story.”Footnote 26
At the CCAR’s core was a belief that an organization representing a broad spectrum of Canadian interests would succeed in securing not only acid rain precursor reductions in Ontario and elsewhere in Canada, but also in persuading American legislators to cut emissions from coal-fired power plants in the Ohio River Valley. As such, efforts were made to include groups from all areas concerned and affected by acid rain. Support from the Canadian environmental community was fundamental to the group’s launch, while its key employees, Adèle Hurley and Michael Perley, had previously worked for the Toronto-based ENGOs Pollution Probe and the Canadian Environmental Law Association.Footnote 27 While it is predictable that strong support would come from the environmentally conscious—acid rain was, after all, a pollution problem—less predictable, but no less vital support came from propertied interests. Of the CCAR’s fifty-six member groups, fourteen fall into this category. These groups include representatives from the agricultural (Canadian Federation of Agriculture, Ontario Federation of Agriculture), tourism (Accommodation Motel Ontario Association, Northern Ontario Tourist Outfitters Association, Resorts Ontario), and forestry (New Brunswick Federation of Woodlot Owners, Ontario Forestry Association) sectors.
Most illustrative of property’s role within the CCAR is the contribution provided by Ontario-based cottage associations. Fueled by wealthy Torontonians’ desire to spend their recreational time outside the city, cottage communities took root in the Kawarthas, Muskoka, and Georgian Bay during the second half of the nineteenth century. As historian Peter A. Stevens has demonstrated, “the newfound automobility of the 1920s” resulted in the mass popularization of Ontario’s cottage country, which had since expanded into northern areas of the province, including the Lake Temagami and Lake of the Woods areas.Footnote 28 Cottage owners’ associations quickly followed to protect the interests of the summertime residents. With acid rain forecast to destroy the lakes and woodlands that made cottage country an ideal respite from the city, concern naturally arose regarding the status of their investment. This explains why the FOCA, an umbrella organization representing the interests of the province’s cottage owners, was among the CCAR’s founding members. In time, individual cottage associations, namely, the Muskoka Lakes Association (MLA), the Temagami Lakes Association, and the Lake of Bays Association, would take up membership in the CCAR.
The MLA would prove particularly important in the fight against acid rain. Membership of the MLA included more than ten thousand cottage owners and many prominent Canadians, notably business magnates Ted Rogers Jr., Doug Bassett, Dixon Chant (director, Argus Corporation), Frank H. Sherman (chairman and CEO, Dofasco), Trevor Moore (vice president, Imperial Oil), Warren Moysey (CIBC), Donald Gilpin “Bud” Willmot (chairman, Molson Industries, Ltd., and owner, Kinghaven Farms), and John Craig Eaton and Frederik Stefan Eaton, heirs to the Eaton’s department store empire, as well as prominent political figures David Lewis and John Black Aird.Footnote 29 Furthermore, as is noted below, the region was the summer home to powerful Americans. Given the influence of these figures, the MLA was seen as a potentially valuable ally by the CCAR. On May 13, 1981, Michael Perley addressed the MLA in an effort to bring the organization onside. As the opening of his speech indicates, the significance of property ownership was a prime motivator: “The lasting impressions and happy memories that thousands hold for the Muskoka Lakes area, myself included, are the outcome of years of hard work by you. You’ve made the investments. You have taken the [financial] risks. You have brought tourism to the area. You have been accommodating hosts to the hundreds of thousands of Americans and fellow Canadians who return to Muskoka year after year.”Footnote 30 This appeal evidently worked as the MLA proceeded to join the CCAR. Jeffrey Shearer, president of the MLA, would likewise assume the presidency of the CCAR. During 1984, the MLA held fund-raisers for the anti–acid rain lobby and, on one occasion in response to solicitations for contributions it distributed, raised $125,000. The MLA would also provide the initial funds necessary to hold the June 7, 1985, dinner featuring Senator Ted Kennedy, which raised $85,000 for the CCAR.Footnote 31
The MLA would spin off two influential organizations: the American Friends of Muskoka (AFM) and the Movement Against Acid Rain (MAAR). The AFM was formed during the summer of 1984 with the explicit purpose of rallying American property owners against acid rain. Consisting of seventy-five families from fourteen states, it featured a heavy concentration from Pennsylvania—a particularly relevant development given the fact that the majority of acid precipitation landing in Muskoka emanated from the Ohio River Valley. The founding meeting featured such distinguished part-time residents as J. Irwin Miller, the former president and chairman of the Cummins Corporation, who had also served as national campaign chair of Nelson A. Rockefeller’s 1968 presidential bid; Olive Phelps, widow of William W. Phelps Jr., the former senior vice president of Mellon Bank; John F. Walton III, the namesake grandson of Pittsburgh’s “coal king”; and Henry Hillman, the venture capitalist and industrialist who held the distinction of being the wealthiest man in Pittsburgh. Guest speakers at the event were Senator Robert Stafford, chairman of the Senate Environment and Public Works Committee, and David Wooley, assistant attorney general, Environmental Protection Bureau, State of New York. The group’s second annual meeting, hosted by Hillman on August 18, 1985, featured the Honorable Drew Lewis, special envoy to the president on acid rain, as the guest speaker. Predominately characterized as a group of Republicans from the Midwest, the AFM used its influence to lobby its impressive list of contacts in the United States, as seen in Elsie (Mrs. Henry) Hillman’s June 12, 1987, letter to Senator John Heinz. Explaining that “when I leave the United States and go to Beaumaris, I tend to become Canadian!” The member of the Republican National Committee further explained that “I hope that you will take the problem seriously and if you cannot suuport [sic] the Mitchell/Stafford bills [acid rain legislation proposed by two U.S. senators], do something yourself to start to alleviate this problem. We have been fooling around with this for too long!”Footnote 32
The MAAR was formed by cottagers in Muskoka and Haliburton (including members of the MLA) with the explicit goal of raising money for the CCAR and the secondary objective of raising general awareness of the problem. Beginning in February 1983, it used resources (such as contact lists shared by other organizations and a Bay Street investment house as a call center) to engage in targeted mailings and telephone campaigns to solicit $25 membership pledges and sell $100 or more per-plate dinner reservations.Footnote 33 One of these large dinners featured Canada’s ambassador to the United States, Allan Gotlieb. The event, held in Toronto on May 9, 1983, raised $54,000 to aid the CCAR. An additional $12,000 was raised that summer through the sale of special tee shirts and a dinner held at the Beaumaris Club on Lake Muskoka.Footnote 34
In addition to the importance of the CCAR and related organizations (and as with Toronto’s urban air pollution in the 1950s), the region’s two metropolitan newspapers, the Globe and the Toronto Star (Star), were active voices in support of pollution abatement. Chief acid rain reporter at the Star, Ross Howard, was particularly aware of the close link between the print media and cottage country. Munton reports that “as Howard well understood, many of the upper management of the Toronto Star had summer cottages in endangered areas. The Muskoka lakes had friends in high places, and not just at the Star. . . . A social network involving influential members of Ontario society came into gear, working in tandem with the network involving the government and the media.”Footnote 35 About the media response, Michael Keating, the chief acid rain reporter at the Globe recalls: “The slant of the stories was that acid rain was a threat, and that governments and industry had an obligation to reduce that threat to tolerable levels. Fairly early on in the coverage the target of a fifty percent reduction in emissions was recommended by federal environment officials, and this became the goal which the media used to judge political actions.”Footnote 36 Both the Star and the Globe ran numerous front-page articles and lengthy features on the topic of acid rain, the latter taking the characteristic of “human interest” stories about the experiences of people coping with the loss of aquatic wildlife and speculating about what it means for the future of the Muskoka region. For example, on October 7 and 8, 1980, the Star printed a lengthy two-article feature called “Acid Rain: Will our lakes survive?” authored by Howard and eventual CCAR co-founder Michael Perley.Footnote 37 Similarly, a full-page article written by Keating and published on July 27, 1981, was titled “Rain of Death” and accompanied with banners reading “Lake once a haven, ‘now everything is going’”; “Cottagers fear a legacy of death”; and “Produced by air pollution, acid rain destroys life.”Footnote 38 These articles, like others produced over a nearly ten-year period by both major Toronto newspapers, contained a mixture of vivid and emotional storytelling, accented with up-to-date information about the science and politics of the problem. Overall, Keating has reported counting more than 3,500 articles and letters on acid rain printed in the Globe alone from late 1977 to the middle of 1993.Footnote 39
The Globe and Star also allowed their pages to be a forum for experts to communicate with the public over the issue. Their op-ed pages commonly carried pieces by scientists and politicians about the problems of acid rain, as did the letters to the editor. Keating recalls: “Letters to the editor played a very important role in the acid rain coverage. They were a forum for politicians, business people, academics, scientists, environmentalists and citizens to contribute directly to the debate. Some people were repeat commentators in The Globe, including Paul Aird, professor of forestry at University of Toronto, Charles Caccia, a former federal environment minister, officials of Ontario Hydro and leaders of the Canadian Coalition on Acid Rain.”Footnote 40 The two newspapers also published articles on the health effects of airborne contaminants. In a September 20, 1985, front-page article, the Globe presented the findings of a study indicating that Ontario children living in areas experiencing a high quantity of acids had decreased lung capacity and higher instances of a range of pulmonary morbidities.Footnote 41
Similarly, the editorial pages of both the Star and Globe were vocal advocates for acid-rain abatement policy. Recalling how the Globe came to adopt a firm editorial stance on acid rain, Keating says: “In the late 1970s the editor, Dick Doyle, decided that acid rain was a serious threat, and the paper should support strong controls. Editorials, backed by editorial cartoons, were often sharply critical of Canadian and U.S. governments for not moving faster to implement such controls. This editorial policy supported the strong calls for acid rain controls coming from environmentalists and from the Canadian government.”Footnote 42
Part of the reason for the CCAR’s and print media’s effectiveness rested in their staff’s close working relationships with each other’s organizations. Keating recalls that “groups such as the Canadian Coalition on Acid Rain, would often trigger a story by suggesting questions that should be asked of a politician or business person. The story would reflect the questioning of that person, and might or might not refer to the Coalition.”Footnote 43 Referring to a Globe article from February 10, 1983, titled “Canada should stop waiting for an acid rain control agreement with the United States and make its own pollution cutbacks now, U.S. Senator Robert Stafford says,” Keating illustrates this relationship: “This is a typical story in which an important news source cannot be ignored. It was also a story arranged by the Canadian Coalition on Acid Rain, which had invited Stafford to Toronto to speak and especially to meet the news media and get coverage.”Footnote 44 Moreover, Keating added that “journalists would often call the Canadian Coalition on Acid Rain for reaction to statements by government or industry officials. If the reporter did not call the Coalition, its representatives would often call the media directly.”Footnote 45 He further commented that the relationship benefitted from the complementary competencies of the CCAR and the media, namely, that the CCAR was in possession of the scientific understanding of the issue and the media were necessary for the CCAR’s objective of arousing public opinion:
Michael Perley and Adèle Hurley of the Coalition would phone or mail information to The Globe on a regular basis, and were always available to provide comments on actions or inaction by governments or industry. They were renowned for what was generally considered to be the best set of files on acid rain available. The relationship was symbiotic. The Coalition needed the media to put pressure on governments to act on acid rain. The media found the Coalition to be a valuable and reliable source of information on a complex subject.Footnote 46
This relationship also existed with the writers of the Star, in particular Ross Howard. To give one example, after the initial round of Ontario regulations on Inco (in 1980) and Ontario Hydro (in 1981) occurred, and the federal government brought U.S. media representatives and politicians to the acid-damaged areas for a tour, it became apparent that Ontario’s stalled efforts were damaging diplomatic relations with the Americans. Howard responded by writing articles underscoring Ontario’s inadequate abatement efforts featuring extensive quoting from Perley and Hurley.Footnote 47 One such article, which spotlighted a January 1982 amendment to the 1981 Ontario Hydro regulation allowing the utility to produce more nitrogen oxide as sulfur dioxide was reduced, contained the following quote from Hurley: “The cabinet’s fiddling with the limits on Hydro emissions won’t fool anyone in the U.S. Legislators there want a blunt answer on whether Ontario has strict controls on its major polluters. The answer here is no.”Footnote 48
Thus the propertied interests seeking to address Ontario’s acid rain problem were a diverse group with overlapping objectives and representing many locally oriented economic elites. Since much of the pollution contributing to the problem originated in the Ohio River Valley, they also sought to influence American pollution policy—with little success in the end.Footnote 49 Yet as we show below, they were of central importance throughout the policy process to address Ontario’s acid rain emissions.
Heavy Industry
The industrial actors in the acid rain story of the late 1970s to mid-1980s represent a different sort than those known to be polluting Toronto’s air during the 1950s. Urban air pollution in Ontario’s largest city had already been substantially reduced, with manufacturers and manufacturing support industries regulated under the 1958 air pollution legislation and automobile emissions regulated provincially a decade later. Left to be regulated were the large coal-fired power plants and smelters located in relatively remote locations. Rather than turning to trade associations for representation as others had, these firms were politically powerful enough by themselves to engage in direct negotiations with provincial regulators.
Ontario Hydro was, at the time, the province’s monopoly electricity utility and a crown corporation that tended to seek as much autonomy as possible in its business dealings. In Douglas Macdonald’s analysis of its role in Ontario’s acid rain program, he asserts that Ontario Hydro sought first and foremost to be a unique entity; second, as a business firm maximizing return on investment; third, lowest on its priorities, as a public agency that would cooperate with the Ontario government on its policy objectives.Footnote 50 Given that, under normal circumstances (that is, not during a politically salient effort at regulation), these plants fell under Ontario’s point of impingement regulatory instrument, Ontario Hydro had never experienced intrusive regulation to the extent that the provincial government would specify the types of abatement technology that must be used in its power plants.Footnote 51 None of its power plants, including its largest polluters—Lakeview, Lambton, and Nanticoke—had been required to switch to low-sulfur coal or install scrubbers to lessen sulfur dioxide emissions.Footnote 52
The remaining major emitters—Inco, Falconbridge, and Algoma Steel—were privately owned metal producers selling their products on the global market. All large employers important for the economies of the towns of Sudbury and Sault Ste. Marie, Ontario, they had considerable influence in the provincial government and had been able to avoid heavy regulation imposing high capital investment costs. Falconbridge had already undertaken emissions reductions during the early 1970s, and along with Algoma Steel emitted substantially less sulfur dioxide than Inco.Footnote 53 During the early 1980s, due to low nickel prices, Inco had lost money on an annual basis, thus providing rhetorical backing for its argument that it could not afford the necessary measures to lower emissions.Footnote 54 The fact that the federal government was willing to finance the modernization of these plants is indicative of their considerable bargaining power. Thus, the efforts of Ontario’s propertied interests to address the problem of acid rain took place in the context of concentrated, powerful, and, at the time, occasionally nonprofitable heavy industry trying to maximize its return on investment and with little economic incentive to take measures to improve the regional environment for which the market for its products did not depend.
Acid Rain Precursor Abatement in Ontario
The policy process resulting in the reduction of acid rain precursors in Ontario occurred in three phases: agenda setting, policy formulation, and political pressure for policy implementation. In the first phase, the province’s propertied interests responded to the Ontario government’s failure to act by raising public awareness of the problem and applying pressure for reductions. This strategy was partly successful, since both Inco and Ontario Hydro agreed to lessen their emissions of sulfur dioxide in response. However, these reductions were minimal and consistent with the range of technological alternatives available at the time that would enable the firms to lessen emissions in an economical manner (i.e., inexpensively or consistent with other long-term planning strategies such as a transition to nuclear power generation). In the second phase, cost-effective technology became known and available for Inco and other metal-processing firms to substantially reduce acid emissions. Consistent with Gonzalez’s findings about the catalytic nature of technology in producing “ecological modernization” policy responses to air pollution, this was also the policy formulation phase. Finally, in the third phase, with a policy response formulated by the Ontario government and collaborating firms and interest groups, these groups applied pressure to the government to require industry to adopt the changes and reduce their emissions.
Agenda Setting and the First Round of Reductions
The political dimension of the acid rain issue in Ontario initiated with the decision by the Ontario Ministry of the Environment (MOE) to rescind a control order on Inco at the end of July 1978. The provincial health-based control order on Inco issued in 1970 was aimed at addressing Sudbury’s local air pollution rather than acid rain and would have reduced sulfur dioxide emissions from 3,600 tons a day to 750. But rather than lessening emissions, Inco opted to build a tall “Superstack”—at 1,200 feet, the tallest chimney in the world—to transport much of its emissions elsewhere. Since the Inco Superstack had improved the ambient conditions in Sudbury substantially, and Inco could challenge the control order on that basis, the provincial government decided not to pursue the reductions Inco had been required to meet by December 1978.Footnote 55
The decision to lift Inco’s control order was met with considerable resistance.Footnote 56 Days later, the Star’s editorial board voiced its opposition forcefully in an August 1, 1978, piece on the basis that the smelter contributed to the acid rain problem outside of Sudbury:
Well, good for Sudbury. But the fact remains that Inco smelters will go on blowing up to 3,600 tons of sulphur dioxide into the atmosphere every day. And if this poisonous waste isn’t coming down on Sudbury, it’s coming down on other places farther away. . . . It may be, as McIntyre [a MOE staff member] said, that nitrogen compounds carried thousands of miles by the wind are an unknown factor in causing acid rain. Still, sulphur dioxide is certainly a known factor and it doesn’t need several years of research by a team of scientists to figure out that adding 3,600 tons a day of it to the atmosphere must be having some effect.Footnote 57
Munton, Keating, and Fenech explain the issue’s importance and its link with the province’s tourism industry:
The phenomenon of acidic precipitation languished while it was only linked to a familiar problem, smelter emissions causing “local” pollution around Sudbury. It became a political issue and a media cause when it was linked to a new and surprising problem, the damage those emissions were causing to popular vacation and fishing lakes hundreds of kilometers away from Sudbury—and much closer to most of those who read Toronto-based newspapers.Footnote 58
Similarly, Tom Brydges, a senior scientist in the MOE who was active in acid rain policy throughout the late 1970s and 1980s attests, “I believe that the perceived threat to the real estate value of cottage property and to the viability of the recreational industries, generated most of the substantial and immediate public reaction.”Footnote 59 Indeed, when the control order was lifted on Inco in 1978, Ontario cottagers’ and anglers’ associations were among the interests publicly opposed.Footnote 60 Reflecting on their political significance at this stage, Munton observes that “the cottagers were not the sort of environmental radicals who would have been turned away at cabinet ministers’ doors; they generally held middle of the road or conservative political values, and were more like born-again conservationists than new age environmentalists.”Footnote 61 Members of the opposition parties and two conservation groups called on Ontario environmental minister George McCague to resign, while the FOCA sought full disclosure of the MOE’s meetings with the firm. Early the following year, as the costs of the acid rain problem became clearer, the executive director of the 300,000-member FOCA publicly stated the following: “We’ve been told about water pollution; we’ve been told don’t eat fish because of mercury poisoning, and now we’re being told our lakes don’t have a hope in hell. Our property values, our lifestyle, an entire economy is being eroded. Put a plug on acid rain!”Footnote 62 Within three weeks of rescinding the control order, in August 1978, McCague was replaced after only seven months as minister of the environment. That fall, when the Ontario Legislature reconvened, acid rain had priority on the agenda.Footnote 63
The government response to acid rain leading to the first round of emissions cuts began in February 1979, when the provincial legislature’s sixteen-member standing committee on resource development conducted hearings on the issue, in which the new minister of the environment, Inco representatives, and many experts testified. Among the points raised in the testimony were that at least forty-eight thousand more lakes, including those in the Muskoka region, were threatened and that half would be dead within a decade, and that the dead lakes would adversely affect the tourism industry and broader economy.Footnote 64 Several months later, in October 1979, the Bilateral Research Consultation Group on the Long-Range Transport of Air Pollutants (BRCG), a fact-finding committee formed by the U.S. and Canadian governments to look into the acid rain issue, released its interim report.Footnote 65 While more focused on the sources and flows of transboundry acid rain, the report underscored the damage acid rain can do to the soil used by crops and forests, as well as the damage it can cause to the built environment.Footnote 66
At this point, newly appointed provincial environmental minister Harry Parrott insisted that no abatement measures would be taken until the United States reached a firm agreement for bilateral reductions, arguing that a cleanup would be too costly for industry. The Globe’s editorial board responded on October 17, 1979, by criticizing Parrott and underscoring the economic basis for action, saying: “If Dr. Parrott’s Government is so concerned with the preservation of jobs, it should take serious stock of the jobs connected with farming, with forestry, with fishing; short fishing in central Canadian lakes alone accounts, with its tourist spin-offs, for $600-million annually.”Footnote 67 In December, two months after the interim report by the BRCG and as the potential consequences for Ontario’s economy became clearer, the Star’s editorial board sought to clarify what was at stake by linking the problem in Muskoka to Toronto:
What has the destruction of distant lakes to do with us in urban Toronto? The answer is, a great deal. First, we live in a highly integrated society, and the loss of any of our natural resources, and the jobs and income they generate, will eventually be felt by all of us. You don’t have to own a cottage in Muskoka to share the loss of Ontario’s total wealth brought about by the crippling of our recreation and tourist industries. Second, if nothing is done to halt the onslaught of acid rain, its destruction will spread. It can eventually stunt growth of forests, damage our food crops and corrode our homes, cars and a host of other goods we hold dear. In the end, everyone in the province will pay. It’s in the self-interest of everyone—whether city dweller or farmer—to develop an understanding of what acid rain is and to encourage those seeking to eliminate it.Footnote 68
In May 1980, responding to the efforts of the newspapers, the FOCA, and other organizations to arouse public concern and influence the provincial government, and despite substantial resistance from Inco, the MOE released a draft control order requiring the smelter to reduce its sulfur dioxide emissions from then-present levels by 25 percent.Footnote 69 Furthermore, the MOE announced the creation of a federal-provincial task force to examine the feasibility of further emissions controls (thus, arguably, lessening the MOE’s reliance on data provided to it by Inco.)
In the wake of Inco’s acquiescence, Ontario Hydro (the province’s public utility and second-largest polluter) also committed to reductions. In 1980, federal studies indicated that the utility could cut its annual emissions of nearly half a million tons of sulfur dioxide in half using existing technology, and that the increase in costs would only result in a 10 percent increase in utility rates.Footnote 70 In January 1981, Ontario Hydro was ordered to reduce emissions by 42 percent over the following nine years.Footnote 71 With an initial estimated cost of $500 million, the plan was to require the utility’s highest-polluting plants to install scrubbers, including Nanticoke, Hydro’s largest coal-fired plant.Footnote 72
Abatement Technology and Policy Formulation
Following the regulatory actions of 1980 on Inco and early 1981 on Ontario Hydro, little else new happened to govern air pollution in Ontario for two years. This changed in December 1982, when the federal-provincial task force set up to investigate Inco’s capacity to lessen emissions reported that the majority of Inco’s sulfur dioxide emissions could be eliminated at a cost of around $500 million (roughly the same amount that Ontario Hydro was considering spending to lower its emissions) with the construction of a roast reduction smelter (RRS).Footnote 73 This available technology and dollar amount served as a basis for negotiations conducted between Inco and the Ontario MOE during the summer of 1983. During these meetings, Inco privately acknowledged that the technology necessary for a 75 percent reduction in sulfur emissions now was available, but the company refused to make the investment until it could be integrated into a strategy for regaining profitability.Footnote 74
Despite continued opposition by Inco and others (most notably, Algoma Steel and Falconbridge), the political momentum for a second round of sulfur dioxide reductions picked up during 1983 and into early 1984, when the federal and provincial environment ministers discussed the possibilities for additional emissions cuts. Beginning in the fall of 1983, a succession of two interprovincial agreements commenced and, by the following March, seven provinces (Ontario, Québec, Manitoba, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland) and the federal government agreed to sulfur dioxide reductions of 50 percent from 1980 levels.Footnote 75 While the specifics of which sources would be regulated and to what extent had yet to be determined, the ministers based their agreement on the understanding that the provinces would take the lead in controlling pollution from coal-fired power plants, and that the federal government would assist in addressing smelter pollution by funding pollution-decreasing modifications. In particular, Ontario’s Falconbridge and Inco smelters were among the six smelters that would be expected to reduce pollution substantially through federally funded modernizations.Footnote 76
The emergent consensus (among policymakers within and outside government) about the need for a federally funded smelter-modernization process is the most significant policy breakthrough during this period because it represents the development of a strategy for reducing emissions substantially beyond what these firms had previously been willing to commit to achieving.Footnote 77 Recognizing that technology to bring about the sought-after reductions existed, the CCAR released a report, written by a member of the federal-provincial task force, on December 20, 1983, recommending a federally funded modernization program involving the construction of the RRS and other measures, totaling $525 million.Footnote 78 The report claimed that new technology would improve the firm’s profitability and that the reductions resulting from the implementation of technology could bring Inco within the limits of the 1970 control order.
At this point the provincial and federal governments were unwilling to commit publicly to this course of action, and instead suggested that it was premature since they were waiting for a report due the following year on the Canadian base metals and smelting industries before further developing policy.Footnote 79 The Star, however, made its preference for this policy alternative known in a January 15, 1984, editorial:
The company says it can’t put out the hundreds of million it would cost for a cleanup because it has been losing money since 1981. It says it “must regain profitability and restore its financial strength before considering (this) financial investment.” But while Inco worries about its profit picture, as many as 48,000 of our lakes face doom. Cleaning up Inco’s mess is absolutely imperative. True, its emissions are less than half of what they were 15 years ago. But the fumes are still a problem. Half of Canada’s acid rain troubles come from homegrown sources, and majority from smelters like Inco’s. It may be that, right now, Inco genuinely needs help paying for its cleanup. If so, it should get it, from both Ottawa and the province.Footnote 80
Afterward, on February 10, 1984, CCAR representatives met with Inco officials to convince them to request federal assistance for smelter-modernization technology.Footnote 81 The CCAR plan was for Inco to release a statement indicating that it would proceed with modernizations with adequate federal assistance. However, Inco indicated at the time that it was not ready to proceed since, as before, CCAR’s plan had yet to be integrated into the firm’s strategy for returning to profitability.Footnote 82
After the Canadian provinces decided to move forward with unilateral reductions (i.e., irrespective of U.S. actions) in March 1984, the Star praised the move and made recommendations on how to proceed, including the use of control orders and financing for modernization. In this March 10, 1984, editorial, the Star stated:
But our decision to cut acid emissions by 50 per cent over the next decade will only be meaningful if it’s backed up by specific action. We need to put realistic control orders on major polluters such as Ontario Hydro and the large nickel and copper smelters in northern Ontario, Manitoba and Quebec. These controls should take us to the 50 per cent, with no extensions or excuses allowed. But industries that need financial help should be able to get it from government, as loans, on the clear condition that the industries eventually pay the money back.Footnote 83
Similarly, in April 1984, the CCAR released proposed regulations with a smelter-modernization program costing Inco $500 million with phased reductions in sulfur dioxide to roughly the levels of the 1970 control order by 1992.Footnote 84
Ontario’s propertied interests therefore participated not only in the early agenda-setting phases of the policy process to address acid rain, but also during the policy formulation phase. The catalytic change enabling the formulation of a policy response occurred when the availability of affordable technology for smelter modernization was established. At this point it became feasible to seek reductions in emissions without severely damaging the province’s industrial base. The next challenge was to convince the polluters to embrace an “ecological modernization” solution.
Applying Pressure and the Second Round of Reductions
With a developing consensus on how to address the province’s (and eastern Canada’s) contribution to the acid rain problem, the CCAR used a variety of tactics to bring about the second round of reductions. In addition to the CCAR’s strategic use of the print media to create stories and express its views, the CCAR attempted to mobilize the public with publicity campaigns aimed at raising the political salience of the issue.Footnote 85 In early 1982, it used radio advertisements featuring popular entertainers and billboards with the words “Who Will Stop the Rain?” which were placed in both Canada and the United States.Footnote 86 These efforts helped to place the issue in the broader public consciousness and, in the following provincial election, acid rain was for the first time a prominent election issue.
The CCAR also commissioned polls in order to underscore the extent of Canadian popular support for acid rain controls and government funding for smelter modernization. In 1982, a Gallup poll commissioned by the CCAR indicated that three out of four Canadians thought that the federal and provincial governments had done little or nothing to address acid rain.Footnote 87 A March 1984 CCAR-commissioned Gallup poll found that 65 percent of Ontario residents supported government funding to limit emissions from Inco’s Sudbury smelter.Footnote 88 It also found that nearly half of Canadians indicated that the government should pay for more than half of the expense, and that most Canadians would be willing to pay $5 to $15 per month to address the problem.Footnote 89 Attending the meeting in Bracebridge, Ontario, at which the CCAR presented the poll results, was federal environment minister Charles Caccia, who commented that the costs of modernizing Canada’s smelters must be weighed in relation to the greater than $20 billion tourism, fishing, and forestry industries damaged by acid rain.Footnote 90 The poll findings were also reported on the editorial page of the Globe on May 11, 1984, which used the opportunity to underscore public support for costly abatement measures:
This sampling of opinion is no mere academic exercise. As Michael Perley, of the Canadian Coalition on Acid Rain, which sponsored the survey, said, “The poll is a demonstration to politicians of the willingness of Canadians to contribute. We are trying to allay concerns that (politicians) might have about imposing an extensive cleanup.”. . . Ultimately, the cost of keeping harmful industrial emissions down should be buried in the cost of the products we manufacture, though it is evident that tax dollars will have to be applied in the initial stages of the battle.Footnote 91
Evidence suggests that these opinion polls were effective in convincing politicians that Canadians would be willing to shoulder the costs of a cleanup, as Ontario environment minister Andrew Brandt commented that they vindicated his position that public funds would have to be spent on nuclear energy development and smelter modernization.Footnote 92 Furthermore, when the federally funded smelter modernization program was informally announced in February 1985, the federal environment minister Suzanne Blais-Grenier mentioned the findings of the polls as a rationale for the policy.Footnote 93
During 1984, Inco worked on formulating a strategy to use the modernization imperative as an opportunity to enhance the efficiency of existing facilities and lower its costs. By the fall of that year, Inco had agreed privately to provincial negotiators that it would reduce its emissions to 350,000 metric tons per year (thus averaging roughly 1,050 standard tons per day).Footnote 94 This represented Ontario’s main contribution to the national program—the Eastern Canada Acid Rain Program (ECARP)—formally announced in March 1985 by the federal government. In it, the provinces signed an accord to reduce their emissions from 1980 levels of 4.6 million metric tons of sulfur dioxide per year to 2.3 million metric tons by 1994, and the federal government agreed to help finance the necessary smelter modernizations.Footnote 95 The exact amount that Inco would be required to reduce sulfur emissions was initially unclear, but Algoma and Falconbridge would not have lowered caps.Footnote 96 Ontario Hydro’s sulfur caps stayed put at 175,000 metric tons. Inco then announced, in April 1985, that it would meet the reductions agreed to months earlier (350,000 metric tons per year) and, surprisingly, stated that it would not use federal funding since it was able to make the reductions for less cost than expected and did not want to meet the conditions of the funding.Footnote 97 This program was expected to bring Inco to about 70 percent below 1980 levels, albeit less of a reduction than had been discussed with negotiators during the summer of 1983. At the time of its announcement, Michael Keating of the Globe, as well as the CCAR, observed that the plan did not actually account for how 14 percent of the 2.3 million metric tons would be reduced.Footnote 98 Further negotiations with Inco continued throughout the year.Footnote 99 Six months following the announcement of the federal ECARP (and three months before Ontario’s Countdown Acid Rain was announced), on September 7, 1985, the editorial page of the Star kept pressure on Ottawa and the provinces to deliver on their commitments, and in particular for an examination of whether Inco had committed to sufficient reductions:
Today, the picture is cloudy. And the forecast doesn’t look good. In the six months since [Canadian prime minister] Mulroney described acid rain as “this vital issue . . . high on the national agenda,” virtually nothing has happened to advance the cleanup. The promised money is still sitting in Ottawa. The provinces, except for Quebec, have done little to get their clean-ups going. . . . [T]he acid rain coalition gave them, except Quebec, all bad marks for what they’ve accomplished in the past six months. . . . Ontario, whose contribution to acid pollution is about half the national total, needs to take stock of its current regulations. Are the cutbacks planned by our biggest polluters, Inco Ltd. and Ontario Hydro, enough to ensure that we’ll meet our 1994 target? Does the government need to impose a stricter timetable? When are we going to see some progress?Footnote 100
By the end of the year, the 300,000-metric-ton shortage had been accounted for. Countdown Acid Rain, Ontario’s acid rain control plan, was announced in December 1985.Footnote 101 It was created with the passage of four regulations under the province’s Environmental Protection Act. Ontario Hydro’s cap was lowered from 260,000 metric tons per year (as specified in the 1981 regulation) to 175,000 metric tons by 1994, which it would accomplish by transitioning to nuclear power over coal. Algoma Steel and the Falconbridge smelter—the province’s third and fourth largest sulfur emitters, respectively, which had both managed to avoid new regulations to that point—were required to reduce their emissions by roughly two-thirds. Inco’s mandated reductions, substantially more than the firm had previously agreed to, capped its emissions at a rough equivalent to the level of the 1970 control order.Footnote 102
In the end, the policy effort was a substantial success. At the time of its announcement, it arguably represented the most aggressive and costly acid rain abatement effort undertaken in North America. Upon its announcement, Adèle Hurley of the CCAR said, “It’s just a great day for the environment in this country—it’s a great, green Christmas present.”Footnote 103 The CCAR’s Michael Perley said “All in all, it sounds like a pretty good program. It’s a major change from what we had before.”Footnote 104 By the end of 1994, sulfur dioxide emissions in eastern Canada stood at 1.8 million metric tons per year, 0.5 million metric tons below the objective of 2.3 million.Footnote 105
Conclusion
During the past century in North America, industry-property disputes over air pollution have tended to follow a familiar pattern. Namely, a coalition of propertied economic interests in a circumscribed locale problematize the issue by quantifying the costs and framing it in a way likely to arouse public opinion, and participate in the formulation of policy options that they encourage policymakers to adopt.Footnote 106 Heavy industry, generally, responds with alternative policy proposals, and the outcome represents a compromise that more or less addresses the problem. Similarly, in the acid rain case study presented here, a coalition consisting of (mostly elite) propertied actors, including cottage owners, tourism associations, agriculture and forestry interests, and Toronto’s two largest urban newspapers, sought reductions of the acid rain precursors threatening to damage property values and the tourism- and agriculture-based segments of the economy. They were initially partly successful, and at the end of the first round of reductions the outcome was a compromise solution whereby propertied interests got a portion of the 50 percent reductions in sulfur dioxide they had sought. Although substantial, these reductions were roughly what the polluters were planning to achieve anyway through a series of efficiency improvements at Inco and by switching to nuclear power at Ontario Hydro. But the problem was not resolved and the issue did not go away, and during the middle of the decade a second and more aggressive round of acid precursor reductions occurred. Unlike in other past disputes over air pollution in both Canada and the United States, here property achieved everything it sought (including a roughly 750-ton-per-day cap of sulfur dioxide emissions on Inco).
An explanation for the difference in outcomes rests in the availability of inexpensive abatement technology to address the pollution. As Gonzalez explains, economic elites (both propertied and industrial interests) prefer ecological modernization over changes in consumption since the former allows economic processes to continue unfettered and therefore does not hinder economic growth.Footnote 107 Cases in which propertied interests lobbied for pollution relief through source modernization, yet in which economical and reliable technology was not available, have tended to result in outcomes favoring inaction. Gonzalez illustrates this with the case of Chicago during the late nineteenth and early twentieth century, which was heavily polluted from coal fumes. In Ontario during the mid-1980s, the opposite was true. Reliable technology to modernize the polluting coal plants and smelters existed in the form of sulfur dioxide scrubbers, a switch to nuclear power, and a range of process modifications.
The turning point in the acid rain case occurred in December 1982, when a federal-provincial task force concluded that a large majority of Inco’s sulfur dioxide emissions could be reduced at a low cost. The CCAR and Toronto’s print media zeroed in on this solution by advocating for the use of available technology, with the CCAR framing acid rain as a “smelter modernization problem” and negotiating with Inco to accept federal funding.Footnote 108 Afterward, as the federal smelter modernization program was formulated and the Ontario government decided at what level to set the smelters’ cap, the CCAR and print media used a number of techniques (including opinion polls and editorials) to maintain pressure on government decision makers to robustly implement the preferred solution. Also, in the mid-1980s, Ontario Hydro was able to commit to switching more of its generating capacity to nuclear, thereby enabling it to further reduce emissions while avoiding the more costly alternative of sulfur dioxide scrubber retrofitting on its coal plants.
The established importance of technology in addressing air pollution casts doubt on historical accounts that highlight normative societal changes or, even more narrowly, jurisdictional developments, in bringing about policy outcomes that differ from those in the past. If the mobilization of propertied interests and the development and availability of technology are among the most significant factors in clean air policy, others have been overstated. In a sense this is intuitive, as the single most important factor enabling urban areas to clean their air during the 1950s was the technological development of switching locomotives and freightliners from coal to liquid fuel. In other studied instances of failed and successful attempts of local activists to abate air pollution, the decisive factor was whether or not the polluter was able to address the problem with economically beneficial modernizations.Footnote 109 This factor is sufficiently important that one instance in which jurisdictional incomparability would have suggested a resolution was improbable (i.e., the Canada-U.S. Trail smelter dispute), the availability of technology enabled a solution that benefited all parties. We should thus reevaluate our articulation of the trajectory of environmental regulation during the last century in light of the importance of technology in facilitating environmentally progressive outcomes.
Furthermore, scholars of environmental policy history should avoid accounts that unproblematically characterize propertied interests as environmental activists (as has occurred in both the Trail smelter and Ontario acid rain cases), thereby conflating them with actor types emerging from the historical environmental movements in the United States and Canada.Footnote 110 Developing this distinction would further refine our efforts to understand who contributes and in what way. Similarly, air pollution policy analysis has occasionally failed to distinguish between policies that bring about substantive responses addressing the problem and those that serve mainly to quell public anxiety and dissatisfaction but offer little in the way of air pollution governance. Studies of both the 1970 United States Clean Air Act and the 1967 Ontario Air Pollution Control Act, for example, have argued that these represent symbolic policy rather statues that brought about the results they ostensibly promised. Yet this distinction is important because evidence suggests that different outcomes are associated with the advocacy of different kinds of actors and different issue salience dynamics.Footnote 111
A final (and related) implication of the role we have outlined for property and technology is about scientific knowledge, which is frequently assigned considerable importance by environmental policy scholars.Footnote 112 Scientific knowledge matters, but at specific points at which it identifies the causes and consequences of problems and encourages actors to mobilize. It does not have an effect independent of those who make cost-benefit calculations on its basis, nor does it necessarily have to be accurate to be effective. The proponents of reductions would never have known about the threat to cottage country had it not been for the work of Canadian government scientists. However, once this understanding was established, they defended the scientific results that supported their cause and used this knowledge in publicity campaigns.Footnote 113 It is now unclear whether forty-eight thousand lakes were really in imminent danger of dying. The dire economic projections were almost certainly overstated. But with sufficient concern over the economic harm of acid rain on the basis of available (although imperfect) knowledge, Ontario’s locally oriented propertied elites provided the political incentive to substantially address the problem.
