The European Union’s plan to limit carbon dioxide emissions trading as a way of meeting climate change commitments will increase the cost of fighting global warming, according to a study released yesterday by the International Energy Agency. But the EU plan would lead to more “real” cuts in emissions, the IEA said. The EU is now struggling to convince other nations that they should meet at least 50 percent of their commitments under the Kyoto climate change treaty by making domestic policy changes; nations such as the U.S. and Australia are fighting this proposal.
