Peter’s work at Acadia Center focuses on cleaning up the energy supply across all sectors of the economy. Driving market-based emissions reductions is at the core of this work, using cap and trade policies such as the Regional Greenhouse Gas Initiative, which Acadia Center has tracked since the program’s early development in the 2000s and which Acadia Center is now promoting beyond the region. Peter also leads parallel efforts to price carbon emissions in the transportation, building, and industrial sectors, and to provide incentives to boost clean energy supply in the electric and thermal sectors. As Massachusetts Director, Peter oversees Acadia Center’s work on grid modernization, electric vehicles, energy efficiency, and renewables in the Commonwealth. Peter received a B.A. in History from Yale, and an M.S. in Environmental Science from Trinity College, Dublin, where he focused on the impact of carbon markets on development in Mexico.
