ACR, in partnership with the Indian Land Tenure Foundation, has developed Guidance for Carbon Project Development on Tribal Lands to facilitate the validation, verification, and registration on ACR of carbon offset projects located on tribal land using an ACR-approved methodology, including both lands held by tribal nations and those held by individuals. The Guidance helps tribes, project developers, and validation/verification bodies understand how to meet the requirements in the ACR Standard for the special circumstances on tribal lands. The work was developed with support from a USDA NRCS Conservation Innovation Grant.
