Program Resources

Greenhouse gas (GHG) reduction projects must reduce emissions or increase sequestration of GHGs in a manner that is real, permanent, verifiable and additional. Additionality is a concept from international GHG project accounting principles that requires a project activity is additional to “business as usual” and would not have occurred in the absence of an incentive provided by a GHG offsets market.

GHG reduction projects registered on the Reserve must be verified by an independent third party as adhering to criteria established in the Reserve protocols. After a project has been positively verified and approved by the Reserve, it is officially registered on the Reserve and issued offset credits known as Climate Reserve Tonnes (CRTs).
