In a previous article in this Journal entitled ‘Institutions and Environmental Performance in Seventeen Western Democracies’ (29 (1999), 1–31), I argued that neo-corporatist institutions delivered superior environmental performance during the first two decades of the modern environmental era (1970–90).For other work on the same or similar themes, see Detlef Jahn, ‘Environmental Performance and Policy Regimes: Explaining Variation in 18 OECD Countries’, Policy Sciences, 31 (1998), 107–31; Martin Jänicke and Helmut Weidner, eds, National Environmental Policies: A Comparative Study of Capacity-Building (Berlin: Springer Verlag, 1997); Markus Crepaz, ‘Explaining National Variations of Air Pollution Levels: Political Institutions and Their Impact on Environmental Policy-Making’, Environmental Politics, 4 (1995), 391–414; Martin Janicke, H. Monch and M. Binder, ‘Ecological Aspects of Structural Change’, Intereconomics, July/August (1993), 159–69; Martin Jänicke, ‘Conditions for Environmental Policy Success’, in M. Jachtenfuchs and M. Strübel, eds, Environmental Policy in Europe (Baden-Baden: Nomos, 1992), 71–97; and Martin Jänicke et al., ‘Structural Change and Environmental Impact’, Intereconomics, January/February (1989), 24–35. This note re-examines the thesis using slightly different data from a more recent time period (19807ndash;95). It also controls for some alternative explanations for environmental performance not included in the original article. The results suggest that the beneficial effects of neo-corporatism for environmental performance are robust. In confirming the results from the earlier analysis, this Note demonstrates the effects of neo-corporatism in unexpected policy areas. The positive results for environmental protection suggest that there may be benefits of neo-corporatist institutions in areas beyond those with which they are traditionally associated.
