A law signed by Gov. Janet Mills last week requires landowners who are participating in the forest carbon credit market to report basic data — including a landowner’s name, contact information, date of enrollment and total enrolled acreage — to the state on an annual basis, information the state will use to create a database and track the impact of carbon credits on Maine’s forests… Maine landowners have so far been reluctant to participate in the forest carbon market. Reporting in 2022 found that only 3.5 percent of the state’s large landowners have made deals to sell their carbon, despite a market that has been around for decades. Small woodlot owners have also been reluctant to buy in, citing payments too low to justify the costs of complying with rigorous standards. The law will not require landowners to report on the financial value of the credits,  and will redact personal identifying information from reports and public records requests.
