The Carbon Knowledge Hub is a public web platform that provides companies, policymakers, and other players with the information required to understand compliance and voluntary carbon markets. It offers factsheets, data, videos, and other resources targeted at different levels of expertise, as well as interviews and articles by other companies already involved in carbon trading.

The Carbon Knowledge Hub was launched by BloombergNEF and the Indonesian Chamber of Commerce and Industry (KADIN) at the BNEF summit in Bali on November 12,2022.

The Carbon Knowledge Hub is an official B20 legacy project for B20 Brazil and B20 Indonesia, and is powered by BloombergNEF. We designed the original brand in 2022 with the colors representing Indonesia, which was hosting the B20 at the time. In 2025 we were tasked by BloombergNEF to update the branding for the B20 in Brazil.

Together with Climatescope and NetZero Pathfinders, the Carbon Knowledge Hub is a part of the BloombergNEF public resources offering.
