At Copenhagen in December 2009, during the much-hyped leaders’ summit to negotiate a climate change deal, American hypocrisy met Chinese obstructionism. Americans demanded emissions reductions without a credible plan at home.

The rest expect reciprocity, and some countries will be in a position to demand it.
