"In 2012 GOP Race, Climate Policy Is a Non-Issue"

"Former Utah Gov. Jon Huntsman formally kicks off his presidential campaign Tuesday, with New York's Statue of Liberty as a backdrop. He's hoping some tired and poor Republicans are yearning for a different kind of candidate. Huntsman holds moderate views on immigration and same-sex civil unions, and he wasn't afraid to serve in the Obama administration, as U.S. ambassador to China.

As governor, Huntsman was also a leader in a regional effort to control greenhouse gases, by capping carbon emissions and trading pollution permits.

"Until we put a value on carbon, we're never going to be able to get serious about dealing with climate change," Huntsman said during a 2008 gubernatorial debate.

Since then, the political climate has changed.
