Recent decades have witnessed increased public concern about vehicle emissions and growing frustration with political inaction and business preferences for the status quo. This article provides historical perspective on such regulatory dynamics by analyzing the Swiss and the Swedish cases of vehicle emission governance in the1970s-1980s. Relying on archival documents detailing the policy process in both countries as well as on international regulatory arenas, the analysis focuses on political solutions for reducing the toxicity of vehicle emissions. It uncovers the influence of national as well as international business groups and the existence of the tension between various national ministries, arising from conflicting environmental and trade-related goals. Is also highlights the importance of different institutional settings in creating the expertise to explain the political outcomes. While the Swiss corporatist system gave a great deal of power to a variety of interest groups at each stage of the political process, the Swedish government invested significant resources in the creation of independent expertise and enjoyed a relative autonomy, despite the importance of the Swedish car industry. The analysis also assesses the importance of the Swiss–Swedish collaboration in overcoming certain obstacles and their contribution to the implementation of stricter regulations in Europe that ultimately occurred at the margins of the European Economic Community.

We examined the change in Swiss suicide rates since 1969, breaking down the rates according to the method used. The descriptive analyses of the main suicide methods are presented. The suicide rates reached a peak in the late 1970s/early 1980s and declined in more recent years. Firearm suicides and suicides by falls were the exception and sustained their upwards trend until the 1990s. Suicide by vehicle exhaust asphyxiation showed a rapid decline following the introduction of catalytic converters in motor vehicles. No substantial method substitution was observed. Suicide by poisoning declined in the 1990s but rose again following an increase in assisted suicide in somatically incurable patients. Suicide is too often regarded as a homogeneous phenomenon. With regard to the method they choose, suicide victims are a heterogeneous population and it is evident that different suicide methods are chosen by different people. A better understanding of the varying patterns of change over time in the different suicide methods used may lead to differentiated preventive strategies.
