A bill seeking to curb greenhouse gases has made its way through the committee process and is on its way to a vote by the House of Representatives.  According to the Washington Post, "The bill calls for a 17 percent reduction in greenhouse-gas emissions by 2020 and an 83 percent reduction by 2050."  Although the bill is considered too weak by some environmental groups, Greenpeace chief among them, a majority of environmentalists appear to approve the bill as being a good first step in reducing the US' carbon emissions.  The bill also has the support of President Obama, although, again, it is weaker than he had hoped it would be, and weaker than the platform he campaigned on.
