The US Environmental Protection Agency has by-passed Congress and given the Obama administration a mandate to regulate greenhouse gas emissions. The decision to use regulation rather than legislation is a controversial one. The Bill was not expected to be debated until at least 2010 and was widely denounced by the Republicans and big business.
Daniel Weiss, of the Center for American Progress, said of the decision: ‘It’s not coincidental that it is happening on the eve of the Copenhagen meeting…. Many of the nations who have already taken steps believe that the US has not done enough, but they can no longer say this is the case.’ Source: Financial Times
