Is there convergence of national environmental policies? An analysis of policy outputs in 24 OECD countries

A central issue of globalisation research is the question whether globalisation leads to the convergence of policies or whether domestic responses to global challenges remain strongly influenced by existing domestic structures. In the field of environmental policy, there is some analysis of the diffusion of policy innovations, but there is a lack of systematic knowledge as to whether this leads to policy convergence at a broad scale. To what extent does environmental policy convergence take place? The analysis of policy development uses a data set covering 22 different environmental policy measures in 24 OECD countries from 1970 to 2005. It reveals increases in the similarity of individual policies across countries, in the homogeneity of their policy repertoires and, particularly, in the strictness of regulations, as well as processes of catching up and overtaking among countries.
