WASHINGTON , APRIL 17, 2009--The Environmental Protection Agency today formally declared that carbon dioxide and five other heat-trapping gases are pollutants that threaten the public health and welfare.

Heritage Foundation environmental policy expert Ben Lieberman reacted to the announcement as follows:

"This clears the way for the most expensive and expansive environmental regulation in history. The EPA approach to regulating CO2 will dramatically affect the lives and day-to-day practices of all Americans... all for a change in the Earth's temperature too small to ever notice.

"The finding opens the door to federal regulation of almost anything that emits carbon dioxide and other greenhouse gases. That includes virtually everything that moves, from cars, trucks and ships to lawn mowers and tractors. The agency could also go after things that stand still-regulating millions of emissions-producing hospitals, restaurants and other commercial buildings.

"The Heritage Foundation's Center for Data Analysis has found that, in just 20 years, the proposed carbon dioxide rules alone would lower gross domestic product by $7 trillion, with single-year GDP losses exceeding $600 billion. Job losses would exceed 800,000 annually for several years. The already-struggling manufacturing sector would be hit especially hard.

"Today's announcement, though expected, is a tremendous disappointment for those seeking policies that will improve the environment without devastating our economy."
