DEEP: Proposed Amendments to RGGI

Regulations for Connecticut's Participation in RGGI

Section 22a-174-31 of the Regulations of Connecticut State Agencies (RCSA), Control of Carbon Dioxide Emissions/Carbon Dioxide Budget Trading Program

Section 22a-174-31 of the RCSA implements Connecticut’s participation in the Regional Greenhouse Gas Initiative (RGGI), a regional carbon dioxide (CO2) emissions cap and trade program. RGGI is a cooperative effort among nine Northeastern and Mid-Atlantic States, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont. The program establishes an annual regional budget of CO2 allowances and each state’s allocations of CO2 allowances under the budget. Affected sources are required to purchase carbon dioxide allowances at auction and surrender an amount of allowances equivalent to the tons of CO2 emitted over a defined compliance period. Proceeds from the regional auction of CO2 allowances are invested in energy efficiency measures and the development of Class I renewable energy sources. 

Revisions effective on December 9, 2013, to Section 22a-174-31 of the RCSA were adopted in accordance with the agreed upon outcome of a two year program review conducted in accordance with the RGGI Memorandum of Understanding between Connecticut and the eight other RGGI states. Specifically, the RGGI states agreed to reduce future regional CO2 allowance budgets and the states’ allocations under each budget to more closely align with current CO2 emissions within the region and drive continued reductions in CO2 emissions from the electricity generating sector. Proceeds from the auction of allowances will continue to be invested in energy efficiency measures and the development of Class I renewable energy sources.
