Congress needs to enact mandatory limits on greenhouse gas emissions, but federal legislation should not impede stricter policies adopted by state and local governments, state and local officials told the Senate Environment and Public Works Committee Thursday.
Twenty-nine states, with a combined population of more than 140 million, have some form of climate action plan and 14 have set greenhouse gas emission reduction targets. Regional cooperation is also emerging, with eight Northeastern states working on a regional greenhouse gas initiative and five Western states signing a pact this week to address global warming.
The local and state officials said the federal government should approach the problem from all angles, targeting emissions from all sectors and adopting higher fuel economy standards, stricter building code regulations as well as aggressively supporting investments in cleaner energy technologies.
