这项承诺是将二氧化碳排放强度从2005年的水平削减40%至45%，这样的话，每万元GDP的排放强度大约为1.75吨二氧化碳。

The pledge is to cut carbon emissions intensity by 40 percent to 45 percent from the 2005 level, which would put emissions intensity near 1.75 tons carbon dioxide per 10, 000 yuan of GDP.

去年和汽车制造商争吵了一通而没有达成自愿减排目标后，欧洲委员会即将迫使汽车制造商限制他们生产的汽车二氧化碳的排放强度。

After a row last year with carmakers, which had failed to meet voluntary emissions targets, the European Commission is about to force them to limit the carbon intensity of their fleets.
