 UNITED NATIONS (AP) - The U.N. climate chief said Thursday he is encouraged by the climate views of the three contenders in the U.S. presidential election.
Republican John McCain and Democrats Barack Obama and Hillary Rodham Clinton have all expressed support for some form of mandatory controls on carbon emissions, usually involving a "cap-and-trade" system that allows polluters to buy and sell allowances.
"I'm really encouraged to see that all three of the presidential front-runners have climate change high on their agenda," Yvo de Boer, executive secretary of the U.N. climate treaty secretariat, told The Associated Press. "So whichever one of them wins, I think it will be good news for climate change policy."
