Last week's Supreme Court decision concerning carbon dioxide emissions from cars was welcomed by all who regret that the United States has lagged far behind in addressing this serious environmental challenge.
The decision gives the Environmental Protection Agency two choices. It could develop, implement and enforce rules to regulate carbon dioxide emissions as a pollutant under the Clean Air Act. Or, it can seek to demonstrate, using science (real science, not political science) why carbon emissions do not contribute to climate change or bad air quality.
Christine Todd Whitman served as the administrator of the Environmental Protection Agency from 2001 to 2003, prior to which she served two terms as the 50th governor of the state of New Jersey.
