NEW YORK (Reuters) - World powers are not aiming for a legally binding pact to fight global warming at a U.N. meeting in Mexico this year and are trying to stop backsliding from a 2009 agreement, the United States said on Tuesday.
U.S. climate envoy Todd Stern, speaking after a meeting of the Major Economies Forum in New York, reiterated the U.S. pledge to cut its emissions some 17 percent by 2020 compared to 2005 levels but declined to outline how that would be done in the absence of U.S. climate legislation.
