The limits of democracy in tackling climate change

Previous research has shown that democracies exhibit stronger commitments to mitigate climate change and, generally, emit less carbon dioxide than non-democratic regimes. However, there remains much unexplained variation in how democratic regimes perform in this regard. Here it is argued that the benefits of democracy for climate change mitigation are limited in the presence of widespread corruption that reduces the capacity of democratic governments to reach climate targets and reduce CO2 emissions. Using a sample of 144 countries over 1970-2011, the previously established relationship between the amount of countries' CO2 emissions and their level of democracy is revisited. It is empirically tested whether this relationship is instead moderated by the levels of corruption. The results indicate that more democracy is only associated with lower CO2 emissions in low-corruption contexts. If corruption is high, democracies do not seem to do better than authoritarian regimes.
