What they do

Inside BeZero Carbon

BeZero rates the likelihood that a credit delivers a tonne of avoided or removed CO2e, covering more than 480 projects across 30+ countries on a forward-looking AAA to D scale.

Ratings are distributed via API and on the Bloomberg Terminal, filterable by registry, vintage and rating, and BeZero reports that 79 percent of buyers now require a BBB+ minimum.

The firm is extending coverage into compliance markets and CORSIA-eligible credits alongside the voluntary market.
