Calyx Global has to date assessed and rated 310 carbon projects across more than 10 different credit types (including nature and technology-based credits) and 6 different crediting standards.

We find variability of quality no matter what parameter is selected (type, standard, country, CORSIA eligibility, and more). Sometimes the variability goes all the way from high risk (i.e. poor quality) to low risk, sometimes it is less broad, but a range (distribution) is nearly always there. While quality credits can be found in today’s market, there are few credit types that consistently deliver high quality.

The same observation is valid for SDG impact. Among certified projects (e.g. CCB, SD VISta, Gold Standard for the Global Goals) we find differences in the evidence of real impact provided. This leads to Calyx SDG Ratings from 1 to 5 stars.

Below are two charts that show a distribution of Calyx Ratings. These charts will be updated as our coverage grows.
