At the 2013 National Symposium on Market Transformation, RAP associate John Shenot joined Ward Lenz of the North Carolina State Energy Office and Ted Aburn of the Maryland State Department of the Environment to discuss how to account for emissions reductions from state energy efficiency policies and programs. Energy efficiency generally has a lower cost than traditional pollution control measures and reduces multiple pollutants, making it an attractive compliance option for state air regulators.  Cautioning that this path is not easy, Mr. Shenot encouraged efficiency program providers to support their air regulators in navigating the new compliance strategy, particularly with regards to EM&V. EPA’s Energy Efficiency and Renewable Energy Roadmap provides a starting point for states to incorporate energy efficiency into their State Implementation Plans, and RAP’s forthcoming paper “Data Sources and Methods for Quantifying the Air Quality Impacts of Energy Efficiency Policies and Programs” will provide a tool for air regulators to begin quantifying expected reductions from energy efficiency initiatives. The conference, sponsored by the American Council for an Energy Efficient Economy (ACEEE) and the Consortium for Energy Efficiency (CEE), brought together policymakers, utility staff, NGOs, behavioral scientists, energy efficiency professionals, as well as local, state, and federal agency personnel in Washington, DC.
