The Regional Greenhouse Gas Initiative, a carbon cap-and-trade program amongst Northeastern states, has established offset credits Afforestation and Forestry. Allowances are awarded based on the additional net carbon that is permanently sequestered in standing biomass and wood products during each period as a result of the project. RGGI also exempts the CO2 emissions from “eligible biomass” from the requirement for the surrender of allowances, incentivizing sustainable forestry practices.
