Obama Pledges Greenhouse Gas Emissions Cuts

The Obama administration formally pledged Tuesday that the U.S. will cut its greenhouse gas emissions by as much as 28 percent over the next decade — the opening salvo in an eight-month sprint toward reaching an international climate change deal. The five-page submission to the United Nations repeats a pledge that President Barack Obama first unveiled four months ago in Beijing and relies on the EPA regulations that have been a centerpiece of his second-term climate agenda. But Senate Majority Leader Mitch McConnell immediately warned international negotiators to “proceed with caution” before trusting Obama’s promise — the continuation of the GOP’s attempt to undermine the administration’s climate strategy at every turn.
