Today’s announcement is long overdue and marks the EPA’s first real response to the April 2007 U.S. Supreme Court ruling, which confirmed that greenhouses gases should be regulated as a pollutant under the Clean Air Act.

The science about global warming is clear. The need to act is urgent. This announcement is further proof that the Obama-Biden Administration is serious about addressing global warming. We will not be waiting another eight years for action.

I will continue working with EPA Administrator Lisa Jackson and my Congressional colleagues to ensure we pass comprehensive climate change legislation that works with current and future regulations within the Clean Air Act.
