这个改变颠覆了《京都议定书》的减排方式，协议中总排放量和每个国家的减排目标通过科学计算确定，每个签约国必须承诺削减自己的排放量。

It is a change from the top down approach of Kyoto in which total emissions targets are determined by the science to one in which individual countries pledge their own emissions cuts.

京都议定书的第二个承诺期比前一期软弱，目前占总排放量85%的一些国家仍没有承担约束力的义务。

The Kyoto Protocol's second commitment period is weaker than its predecessor and there are presently no binding obligations for countries with 85 per cent of total emissions.
