COPENHAGEN – Copenhagen, Denmark’s capital, wants to be the world’s first CO2-neutral city by 2025. But, as many other well-meaning cities and countries have discovered, cutting CO2 significantly is more difficult than it seems, and may require quite a bit of creative accounting.
哥本哈根——丹麦首都哥本哈根寄希望于到2025年成为世界首座二氧化碳中性城市。但其他许多善意的城市和国家已经发现，削减碳排放远不像表面看上去那样简单，可能在相当程度上需要在账目上做手脚。
