家园 这篇文章指出一些问题

总结如下:

The demand for carbon credits comes mostly from within the ETS, from polluters who need certificates allowing them to emit carbon. There is some demand from Japan, which has a voluntary scheme, and from companies and individuals elsewhere in the world who want to offset their emissions for moral reasons, or to make themselves look good.
就是说作CDM的动机很多是欧洲或者日本企业,他们为了做branding或者企业的社会责任的目的,购买排放权,并不是真心为了降低全球的温室气体排放。

Credits costing less than 1 to produce have been sold on the market for up to 11. Factories have found that their damaging by-product, HFC-23, can be more valuable than their main output.

还出现逆向选择的问题,中国企业不是去减排,而是寻找HDC-22的替代品,那玩意儿的效率和价格比CO2强多了。

此外,

Chinese CERs are too cheap and the carbon price is too low and too volatile. Even when it was bouncing around at 15-25, it did not seem to encourage much new investment.
中国的排放太便宜,使得Phase I的价格非常低,没有起到鼓励大家减排的目的。

最后还发现,Economist持一贯的有色眼镜看中国的发展,虽然文字安排很巧妙
