Greentons
Greentons are a unit used in climate accounting to quantify the net environmental benefit of greenhouse gas mitigation projects. Conceptually similar to carbon credits, one Greenton represents one metric ton of CO2 equivalent avoided or sequestered, adjusted for factors such as additionality, permanence, and leakage to ensure comparability across projects.
