自《京都議定書》談判以來，已開發和開發中國家在減量責任分配和氣候補償議題就一直爭論不休，本文從道德角度著手，深入分析國際氣候政治的南北關係。本文發現，利益是國際氣候政治的核心，氣候正義為開發中國家提供有利的論述，合理化對抗已開發國家的行動和作為。然而，當開發中國家的人均排放量超過世界平均水準之後，已失去拒絕減排承諾的合理性，而中國氣候政策立場逐漸轉變，也將對國際氣候政治的南北關係帶來正面的影響。

Developed and developing countries have been quarrelling with the distribution of for emission reduction and climate compensation since the Kyoto Protocol negotiation was set up. Notwithstanding that the Protocol, originally due to expire in 2012, was amended to accommodate a second commitment period until 2020, international climate cooperation remains stagnant. Disagreement over political and economic interests is the main cause hindering progress in constructing a global governance mechanism for climate change. Moreover, different approaches to the moral aspects of climate change taken by developed and developing countries also play a significant role. Thus, studies of conceptual loci in environmental ethics between the North and South allow us to understand international climate politics more effectively. This paper concludes that the morality of climate change advocated by the South is gradually losing its lure while the more industrialized developing countries, mainly China, have achieved many economic goals. In particular, China's per capita emission has exceeded that of the developed countries, reducing the legitimacy of her proposition for climate ethics. Relations between the North and South will surely improve in such circumstances, while China begins to adjust her attitudes toward emission reduction.
