Our Offering

We at the Crypto Carbon Ratings Institute assist companies in the crypto space in understanding and managing their climate impact. Our approaches root on a sound data basis and span across all layers of technology and business.

Cryptocurrency Sustainability API

CCRI’s Cryptocurrency Sustainability API provides data on the climate impact of cryptocurrencies, tokens and respective activities. Our methodology is based on a hybrid approach which takes into account the carbon exposure of holdings and transactions. We cover:

  • Proof-of-Work currencies: Bitcoin, Ethereum, Litecoin, and more!
  • Proof-of-Stake currencies: Cardano, Avalanche, Solana, and more!
  • Layer-1 tokens: Uniswap, Chainlink, and more!


Our API already covers a wide range of tokens and functionalities but remains in constant development and is regularly expanded.
