> Released in May 2022, The Investment of RGGI Proceeds in 2020 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 2020 include:

> $1.9 billion in lifetime energy bill savings

> 6.6 million short tons of CO2 emissions avoided

> These benefits are limited to the direct benefits arising from specific 2020 projects, and do not include larger macroeconomic effects that may occur as a result of the RGGI cap and market signal.
