Share green roles fairly

Much has been talked about the need to take action on climate change. Indeed, the globe cannot afford waiting any longer as greenhouse gas emissions are rising more rapidly than most climate scientists had expected.

However, no solution to fight global warming will be genuine enough, and thus practical enough, if developed countries keep glossing over their historical responsibility on this issue.

Speaking after a China-European Union summit in Prague, Jose Manuel Barroso, the European Commission president seized on Washington's latest effort to raise fuel efficiency standards and reduce carbon emissions to nudge China to "engage fully" on the subject.
