This working paper offers detailed analysis of our survey of economic experts on climate change issues. We surveyed all those who published an article on climate change in a highly ranked economics journal over the past 20 years. The survey focused on estimated climate impacts and appropriate policy responses, and the results reveal several areas where expert consensus exists on these issues.

Global actions on climate change have already helped the United States avoid more than $200 billion in direct economic damage. Trillions of dollars more for the United States are at stake in securing commitments for future emissions reductions from foreign countries.

Coal mining on federal lands accounts for more than 40 percent of all coal produced in the United States. But outdated policies, longstanding loopholes, and prevalent environmental externalities keep American taxpayers from receiving their fair share of value from federal coal leases.

Methane, the primary component of natural gas, is a potent climate pollutant up to 86 times more powerful than carbon dioxide on a 20-year timeframe. Currently the United States loses at least 1 to 3 percent of its total natural gas production each year when methane is leaked or vented to the atmosphere. Federal regulations could reduce methane emissions by up to 50 percent at little or no net cost, using available technologies.

This Essay examines and explains the positions of the principal interest groups over the past four decades with respect to the two central questions of environmental policy: the appropriate policy goal and the instrument that should be used to carry out the policy. While environmental groups and industry have largely switched positions on the two central questions of environmental policy, the points at which their positions overlapped were fleeting, and opportunities to make substantial progress in rationalizing the system of environmental regulation have largely been unrealized.
