In a move that will accelerate state and regional efforts to combat climate change while continuing to grow the economy, Massachusetts joined with eight other Northeastern and Mid-Atlantic states participating in the Regional Greenhouse Gas Initiative (RGGI) on August 23, 2017, to announce a plan to reduce greenhouse gas emissions beyond 2020. As the result of extensive RGGI program review conducted by the states over 18 months, the proposal calls for an additional 30 percent cap reduction between 2021 and 2030, relative to the RGGI 2020 levels
On December 28, 2018, the Massachusetts Department of Energy Resources (DOER), acting under the statutory authority of G.L. c. 25A, §§ 6 and 13, G.L. c. 21A, §22, and in conformance with G.L. c. 30A, held public hearings on proposed amendments to 225 CMR 13.00, the DOER CO2 Budget Trading Program Auction Regulation, concurrent with MassDEP’s revisions to 310 CMR 7.70: CO2 Budget Trading Program. Together, these amendments implement the changes announced by Governor Baker on August 23, 2017, to revise the Regional Greenhouse Gas Initiative (RGGI) program by reducing the regional cap and implementing programmatic changes, including the auction process, consistent with a model rule developed by the nine RGGI states. The overall changes to the RGGI program will cause real reductions in greenhouse gas emissions and, in accordance with the Green Communities Act, the economic proceeds will be invested in programs to promote energy efficiency, conservation and demand response.
