The Electricity Generator Emissions Limits (310 CMR 7.74) is a regulation that establishes a declining limit on carbon dioxide (CO2) emissions from large power plants in Massachusetts. The limit is designed to ensure that state programs, including the Clean Energy Standard, reduce greenhouse gas emissions.
The current regulation, 310 CMR 7.74: Reducing CO2 Emissions from Electricity Generating Units, was finalized in August 2017, amended in both December 2017 and August 2018, and repromulgated in December 2020. The regulation is part of the Air Pollution Control regulations (310 CMR 7.00).
The regulation includes the following key provisions:
The Massachusetts Carbon Allowance Registry is a tracking system that enables designated representatives to register their facilities, receive or transfer allowances, and manage their allowance holdings. The registry is administered by the Massachusetts Department of Environmental Protection (MassDEP).
The Market Monitor provides written reports on the outcomes of Carbon Allowance Registry allowance auctions. The reports include information on the number of allowances sold, the clearing price, and the total revenue generated.
The Market Monitor also provides quarterly reports on the allowance market, including transfers in the Carbon Allowance Registry and the conduct and outcomes of allowance auctions.
