{"slug":"tokenized-carbon-credits","question":"Which tokenized carbon credits exist, and how many tonnes are on chain?","answer":"4 carbon credit tokens in our data, together about 20 million tonnes of CO₂ in circulation: BCT 15,678,264 t, MCO2 2,789,331 t, NCT 1,536,344 t, CHAR 816 t.","shortAnswer":"4 carbon credit tokens in our data, together about 20 million tonnes of CO₂ in circulation: BCT 15,678,264 t, MCO2 2,789,331 t, NCT 1,536,344 t, CHAR 816 t. The quality differs by pool: BCT accepts older and cheaper credits, NCT only nature-based ones, CHAR biochar removals. Verra stopped new tokenization of its credits in 2022, which is why supply has hardly grown since.","asOf":"2026-10-16","faq":[{"q":"Can I offset my emissions with a carbon token?","a":"Only if the token is retired — burned with a retirement certificate — not by holding it. Holding a token is owning a credit; offsetting means retiring it so nobody else can claim the same tonne."},{"q":"Which of them can I buy without KYC?","a":"None of them is stated as buyable without KYC."}],"count":4,"rows":[{"ticker":"BCT","name":"Toucan Base Carbon Tonne (BCT) — pool of tokenized Verra carbon credits","issuer":"Toucan Protocol","category":"Carbon Credits","yield":"Not stated by the source","yieldPct":null,"yieldKind":null,"minimumUsd":null,"size":"15,678,264 tonnes (Polygon 15,677,735; Celo 529; read on chain 2026-10-18)","chains":"Polygon, Celo","country":"Decentralized protocol","kycSecondary":"unknown","maturity":null,"lifecycle":"live","isin":null,"contract":"0x2F800Db0fdb5223b3C3f354886d907A671414A7F","source":"https://github.com/ToucanProtocol/contracts/tree/main/deployments/production","lastVerified":"2026-10-16T19:00:00.000Z","tier":"imported","page":"https://tokenbank.world/token/BCT","json":"https://tokenbank.world/api/tokens/BCT"},{"ticker":"MCO2","name":"Moss Carbon Credit (MCO2) — tokenized Amazon REDD+ carbon credits","issuer":"Moss (Moss.Earth, Brazil)","category":"Carbon Credits","yield":"Not stated by the source","yieldPct":null,"yieldKind":null,"minimumUsd":null,"size":"2,789,331 tonnes (read on chain 2026-10-18)","chains":"Ethereum","country":"Brazil","kycSecondary":"unknown","maturity":null,"lifecycle":"live","isin":null,"contract":"0xfC98e825A2264D890F9a1e68ed50E1526abCcacD","source":"https://etherscan.io/token/0xfC98e825A2264D890F9a1e68ed50E1526abCcacD","lastVerified":"2026-10-16T19:00:00.000Z","tier":"imported","page":"https://tokenbank.world/token/MCO2","json":"https://tokenbank.world/api/tokens/MCO2"},{"ticker":"NCT","name":"Toucan Nature Carbon Tonne (NCT) — pool of nature-based carbon credits","issuer":"Toucan Protocol","category":"Carbon Credits","yield":"Not stated by the source","yieldPct":null,"yieldKind":null,"minimumUsd":null,"size":"1,536,344 tonnes (Polygon 1,413,796; Celo 122,548; read on chain 2026-10-18)","chains":"Polygon, Celo","country":"Decentralized protocol","kycSecondary":"unknown","maturity":null,"lifecycle":"live","isin":null,"contract":"0xD838290e877E0188a4A44700463419ED96c16107","source":"https://github.com/ToucanProtocol/contracts/tree/main/deployments/production","lastVerified":"2026-10-16T19:00:00.000Z","tier":"imported","page":"https://tokenbank.world/token/NCT","json":"https://tokenbank.world/api/tokens/NCT"},{"ticker":"CHAR","name":"Toucan Biochar (CHAR) — pool of biochar carbon removal credits","issuer":"Toucan Protocol","category":"Carbon Credits","yield":"Not stated by the source","yieldPct":null,"yieldKind":null,"minimumUsd":null,"size":"816 tonnes (Base 171; Celo 645; read on chain 2026-10-18)","chains":"Base, Celo","country":"Decentralized protocol","kycSecondary":"unknown","maturity":null,"lifecycle":"live","isin":null,"contract":"0x20b048fA035D5763685D695e66aDF62c5D9F5055","source":"https://github.com/ToucanProtocol/contracts/tree/main/deployments/production","lastVerified":"2026-10-16T19:00:00.000Z","tier":"imported","page":"https://tokenbank.world/token/CHAR","json":"https://tokenbank.world/api/tokens/CHAR"}],"programs":[],"underlyings":[],"sources":[{"label":"Toucan Protocol: production deployments (GitHub)","url":"https://github.com/ToucanProtocol/contracts"}],"_links":{"page":"https://tokenbank.world/answers/tokenized-carbon-credits","index":"https://tokenbank.world/api/v1/answers"},"_citation":"TokenBank, “Which tokenized carbon credits exist, and how many tonnes are on chain?”, https://tokenbank.world/answers/tokenized-carbon-credits (data as of 2026-10-16), CC BY 4.0.","_license":"CC BY 4.0 — https://creativecommons.org/licenses/by/4.0/","_disclaimer":"Computed from sourced data; yields are variable and not guaranteed.
