| Abstract |
In this study, we investigated which greenhouse gas (GHG) emission sources have contributed to worsening global warming and which GHG mitigation efforts have been effective and finally evaluated the relative efficiency of OECD 20 countries in reducing total GHG and CO2 emissions under the Kyoto Protocol regime. We applied the effect model of the stochastic frontier model. The main findings are as follows: First, it appears that the manufacturing, electricity and transportation sectors are mainly to blame for the worsening of global warming. Second, innovations in green technology are an effective method for mitigating global warming. Third, Germany is identified as the most efficient country in reducing CO2 as well as total GHG emissions, even though Germany emits the most GHG and CO2 among the target 20 OECD countries. |
