What they do

Inside Calyx Global

Calyx rates credits along two distinct axes, a GHG rating for climate integrity and an SDG rating for sustainable-development contribution, an approach well matched to nature-based projects with community co-benefits.

In January 2025 it moved to an AAA to D scale grouped into three tiers, and by 2026 held more than 1,000 GHG and 500 SDG ratings.

Its ratings are now delivered on the Bloomberg Terminal alongside project, pricing and market data following a January 2026 collaboration.
