Early next year, Lisa Jackson will step down from her 4 year tenure as Environmental Protection Agency chief. Known for her aggressiveness, she fought long and hard with Republicans looking to curb the Environmental Protection Agency’s powers. She also was instrumental in pursuing the first U.S. greenhouse-gas regulations, though she eventually came up short of President Obama’s goal of passing legislation to battle global warming with a carbon tax.
Serving from President Obama’s first term she said she is leaving the EPA “confident the ship is sailing in the right direction, and ready in my own life for new challenges, times with my family and opportunities to make a difference.” She said she will depart after the President’s State of the Union address.
