The implementation of climate change related policies at the subnational level: An analysis of three countries

The objective of this article is to analyze the implementation of climate change related policies by subnational governments in 3 countries: Japan (Mie Prefecture), Germany (Saxony-Anhalt) and Brazil (Sao Paulo). Through an empirical research, the article develops the 3 cases to understand the achievements and obstacles to implement mitigation and adaptation policies. The cases provide an interesting sample, including countries that range from a developed country more pro-active in environmental international negotiations (Germany) to a more conservative developed country (Japan) and a developing country (Brazil).
The results have pointed that, as compared to adaptation, mitigation policies (such as energy conservation) have a much longer implementation history and government support at the subnational level, especially in more progressive governments, but adaptation policies have gained space in the policy agenda recently because of the increasing public interest. The success of implementation of climate related policies is linked to the way they are integrated with sectorial policies, with policies of other levels of government, with civil society and within themselves (integration of mitigation–adaptation policies).
