Planning for compliance with the U.S. Environmental Protection Agency’s Clean Power Plan (CPP) is raising many questions for state regulators. How, for example, will compliance affect voluntary and regulatory renewable energy markets? How can carbon trading under mass-based and rate-based programs be coordinated with existing renewable energy credit (REC) trading? RAP teamed up with the Center for Resource Solutions and the Clean Energy States Alliance for a webinar on November 19 to answer these questions and explore other issues associated with renewable energy markets and CPP compliance. In this 60-minute session, speakers Todd Jones (CRS), Ed Holt (on behalf of CESA), and David Farnsworth (RAP) examine emissions allowances and emission rate credits, potential interactions with RECs from voluntary and compliance markets, potential impacts on renewable portfolio standard (RPS) markets, and how RPS programs can help states meet their emission reduction goals.
