What are the chances that Congress will pass a comprehensive climate change bill this year? Well, this article from Reuters makes it sound highly unlikely, with key senators expressing their doubts on the record. But then again, another article from Reuters--published a day later--makes it sound as if Sen. John Kerry (D-Mass.) is committed to getting something done this year.

With a climate change bill stalled in Congress, the Environmental Protection Agency has been moving forward with plans to regulate greenhouse gas emissions itself. But there are plans afoot in the Senate to bring those efforts to a halt, according to an article in The Washington Post.

Meanwhile, the private sector appears increasingly willing to move on its own. None other than retailing behemoth Wal-Mart announced last week, according to an article in The New York Times, that it intends to cut about 20 million metric tons of greenhouse gas emissions from its supply chain by the end of 2015, the equivalent of removing more than 3.8 million cars from the road for a year.
