Visiting RFF Scholar
Nigel Purvis is a Visiting Scholar at RFF, a non- resident scholar at the Brookings Institution and president of Climate Advisers, Inc. He previously directed U.S. environmental diplomacy as deputy assistant secretary of state for oceans, environment and science, and served as vice president for policy and external affairs worldwide at the Nature Conservancy.
Importantly, Purvis strongly recommends that the president and Congress handle the most significant climate change agreements- ones that would limit U.S. greenhouse gas emissions, change the terms of international trade, or impose substantial costs on the U.S. economy or treasury- as congressional-executive agreements, which require approval by a simple majority of both houses of Congress.
As a matter of U.S. law, Purvis shows that virtually any international agreement the United States rightfully could join as a treaty could also be implemented as a congressional-executive agreement. He shows how handling climate agreements this way would speed the development of a genuinely bipartisan U.S. climate change foreign policy, improve coordination between the executive and legislative branches, strengthen the hand of U.S. climate negotiators to bring home good agreements, increase the prospects for U.S. participation in those agreements, protect U.S. competitiveness, and spur international climate action.
More specifically, Purvis argues that Congress should enact "Climate Protection Authority," which would define U.S. negotiating objectives in a statute and require the president to submit concluded congressional-executive agreements to Congress for final approval.This approach, Purvis recommends, should apply both to the post-Kyoto global climate change agreement now being negotiated in the United Nations by the United States and the rest of the international community, as well as to other future arrangements with a smaller number of major emitting nations, regardless of the substantive climate obligations those agreements may contain.
