Featured Article New Uses of Old Tools? Greenhouse Gas Mitigation with Agriculture Sector Policies

Abstract Following the failure of legislative proposals for a multi-sector greenhouse gas (GHG) cap-and-trade policy, the shift in focus to energy sector policies ignores the perhaps substantial potential for GHG mitigation from agriculture/forestry. We review estimates of the current U.S. agriculture sector contribution to GHG mitigation from a portfolio of existing sector policies in bioenergy, conservation, and research and development to compare accomplishments across programs. We then consider what opportunities and challenges may exist for increasing sector GHG mitigation by retargeting and/or expanding current programs—or for bioenergy-related mitigation, implementing proposed new programs—to serve as an alternative to cap-and-trade. Key words: Climate change, Greenhouse gas (GHG) mitigation
