COP15 concluded the“Copenhagen Accord”with take note of all participant countries, but failed to reach a broad agreement that binds all of countries. This reluctant result is partly due to objection of many developing countries, including some Asian countries, which regard strong regulation on global environment as interference to their growth and development. This study tries to estimate environmental Kuznets curve (EKC) for various indicators based on cross-section data provided as Environmental Performance Index (EPI) developed by Yale and Colombia Universities. The inverted-U shaped EKC suggests that economic development does not conflict with global environment quality in long-term. The estimation results support inverted-U shaped EKC for some EPI individual indicators but fails for others. The existence of inverted-U shaped EKC, however, does not deny efforts to reduce or mitigate environmental burdens at all. Considering situations of Asian income situation and present global environmental issues, it is absolutely required to take some reducing or mitigating measures against environmental burdens.
