Outgoing EPA Administrator Proud of Ruling That Greenhouse Gases Endanger Public Health

Expanded the EPA's regulatory authority without an act of Congress

As she prepares to step down from her position as administrator of the Environmental Protection Agency, Lisa Jackson said she is proudest of presiding over the landmark finding that climate-changing greenhouse gases endanger public health and welfare.

"Americans are back to believing that something is happening with our climate and that mankind has a role to play in that. These are not natural phenomena," said Jackson in her first newspaper interview since announcing on Dec. 27 that she would leave the EPA.
