In 1990, the United States passed groundbreaking amendments to the Clean Air Act to combat acid rain. This legislation has saved countless lives, spurred innovation, and helped lay the groundwork for more ambitious climate policy. But as one might suspect, it was a major legislative battle. And one part largely ignored in the literature on this momentous legislative achievement was a proposal from the infamous Senator Robert Byrd of West Virginia. He and a group of lawmakers fought for substantial funding for coal workers that would be put out of work by the acid rain law. We tell the story of this legislative battle, which highlights themes discussed in the book. We then contrast the Appalachian coal transition with Germany's coal phase-out, including how their political and social systems facilitate or frustrate transitions.

The aim of this chapter is two-fold. First, the authors present a practical application of multidisciplinary research based on the experience of editing a book comprised of multidisciplinary cases and focusing on two chapter cases. There are many theoretical accounts of how one may approach multidisciplinary research, but here the authors aim to offer a practical account of how the theoretical goal of multidisciplinary research can play out in the ‘real world’. After addressing the current conceptual understanding of multidisciplinary versus interdisciplinary research, the authors will explain how useful these concepts, in fact, are when applied to the typical constraints that many academics face today in conducting joint research. The authors, who are both editors of the book, will provide lessons for future multidisciplinary collaboration and suggestions for developing methods of multidisciplinary research.

In this chapter, the air pollution trends in historical London (1950 – 66) and contemporary Beijing (2000 – 16) are compared. In both cases, coal is the main source of air pollution, due to coal-fired electricity generation and coal-burning activities that provide heating. In London, the Clean Air Act of 1956 marked a successful milestone in the history of air pollution abatement in the UK. In Beijing, various policies have been introduced but air qualities in China have not been improved substantially. By examining the effectiveness of respective pollution control regulations/policies in a broader socioeconomic context, policy implications on respective jurisdictions are drawn. For effective implementation of air pollution control policies at the local level, it would be good for China to move beyond simply introducing stringent policies and regulations at the central or the provincial level. More resources can be re-directed to resolving the competing interests of stakeholders across different levels of jurisdictions.

Solar geoengineering is presently being researched through indoor work and outdoor experiments without potential transboundary impacts. Existing national and subnational legislation and common law govern such activities, including for their environmental risks, and is an essential component of the existing governance framework within which solar geoengineering is developing. To offer a case study, this chapter reviews applicable American law. The United States was chosen because its environmental legal regime is among the most elaborate and influential, and because solar geoengineering research is presently moving forward most rapidly there. The text considers three major pieces of federal environmental legislation: the Clean Air Act, the National Environmental Policy Act, and the Endangered Species Act. Liability for harm, which is found in the common law of torts, is briefly introduced. Thereafter, the chapter describes relevant laws regarding weather modification and marine pollution, as well as a federal geoengineering bill. A salient question throughout this concerns the extraterritorial application of US law.
