World Resources Institute President Andrew Steer notes that more than 50 developing countries are now implementing costly policies to reduce climate change. From the perspective of national interest, that makes no sense at all, given the global-commons nature of the problem.
世界资源研究所（World Resources Institute）总裁安德鲁·斯蒂尔（Andrew Steer）指出如今有超过50个发展中国家正在实施代价高昂的政策来减缓气候变化。考虑到这个问题全球共同分担的本质，再从国家利益的角度上看，此举根本是说不通的。
