Investments of Proceeds

The RGGI states issue CO2 allowances that are distributed almost entirely through regional auctions, resulting in proceeds for reinvestment in strategic energy and consumer programs. Programs funded with RGGI investments have benefited local businesses, low-income communities, industrial facilities, and households throughout the region.

Released in June 2023, The Investment of RGGI Proceeds in 2021 report tracks the investment of the RGGI proceeds and the benefits of these investments throughout the region. The lifetime benefits of RGGI investments made in 2021 include:

  • $1.2 billion in lifetime energy bill savings
  • 4.4 million short tons of CO2 emissions avoided

These benefits are limited to the direct benefits arising from specific 2021 projects, and do not include larger macroeconomic effects that may occur as a result of the RGGI cap and market signal.

Proceeds were invested in programs including energy efficiency, clean and renewable energy, beneficial electrification, greenhouse gas abatement and climate change adaptation, and direct bill assistance. Energy efficiency continued to receive the largest share of investments.

The report also contains a brief summary of cumulative RGGI investments and their benefits.
