Carbon Credit Rating
An independent assessment of how likely a carbon credit is to deliver the climate impact it claims. Rating agencies such as MSCI and Calyx Global weigh risks like additionality, permanence and over-crediting, and publish a grade for each project they cover.
Why a carbon credit rating matters for carbon credit buyers
Project documentation is written by the projects themselves, so an independent rating is one of the few outside quality signals a buyer can rely on. Rating agencies such as MSCI and Calyx Global assess how likely a credit is to deliver a real tonne of avoidance or removal, weighing additionality, permanence, leakage and over-crediting risk, and publish a grade for each project they cover. Ratings from different agencies use different scales and methods, so compare like with like and read the reasoning, not just the grade.
