The Bush administration rejected an attempt by California and several other states to combat global warming by placing a cap on greenhouse gas emissions from vehicles. Stephen Johnson, head of the U.S. Environmental Protection Agency (EPA), announced the decision Dec. 19, 2007. Environmental advocates and members of Congress have sharply criticized the decision, and several states have already filed suit in federal court hoping to overturn it.

In 2007, new regulatory policies and the inability of federal agencies to protect the public made headlines more so than at any time in recent memory. Four themes dominated regulatory policy this year: an increase in White House influence over agency rulemaking activity and discretion, which added a perception of more political manipulation; the inability of the federal government to protect the public by ensuring the safety of imported goods; the voice of some industry groups calling for regulation; and the Bush administration's refusal to regulate in the face of overwhelming scientific evidence, as in the case of climate change. At best, government has attempted to respond to crises instead of getting ahead of the curve. This has left the public uncertain about whether we can count on our government to provide adequate safeguards.
