RGGI releases updated Model Rule, tightening CO2 cap

After a comprehensive two-year program review, the nine Regional Greenhouse Gas Initiative (RGGI) participating states released an updated Model Rule, planning the program’s first major overhaul since its 2008 initiation.

If adopted by the states, the updated Model Rule would tighten the program’s 2014 CO2 budget, or “cap,” by 45 percent -- from 165 million to 91 million short tons (to match actual emissions from 2012). Actual emissions in RGGI states have fallen well below RGGI’s original cap due to a variety of factors including the low cost of natural gas. The new cap would decline by 2.5 percent each year from 2015 to 2020, aiming to surpass the states’ current goal of reducing CO2 emissions from the power sector 10 percent between 2009 and 2018.

Besides making adjustments to the cap, the updated Model Rule includes provisions to expand its offset program, most notably by adding a forestry protocol. This protocol was modeled after the forestry offset protocol under California’s cap-and-trade program, which emphasizes conservation and reforestation.

Other additions in the updated Model Rule include the creation of a cost containment reserve (CCR) of allowances, denominated by one short ton of CO2 per year. The creation of a CCR would provide a fixed additional supply of allowances, but would only be “triggered” and made available if allowance prices exceed predefined price levels. The CCR provisions would also simplify existing compliance flexibility measures.

Analysis of the updated Model Rule indicates that the proposed changes would result in allowance prices of approximately $4 in 2014 and $10 per allowance by 2020, compared to less than $2 in 2012. The updated program would cause average electricity bills for residents in these states to increase by less than 1 percent, but would generate $2.2 billion for investments in energy efficiency and reduce greenhouse gas emissions from the power sector by about 15 percent from current levels.

The next step is for the updated Model Rule to be formally adopted by RGGI member states through legislative or regulatory processes.
