The landmark American Clean Energy and Security Act, also known as the Waxman-Markey for its authors and sponsors, Henry Waxman (CA) and Ed Markey (MA), passed in the US House of Representatives. It was blocked and never voted on in the Senate. Had it been enacted, it would have established a national cap & trade systems to reduce greenhouse gas emissions.
