Helsinki-based carbon registry provider Puro.earth has launched a new standard and registry for environmental attributes, initially tracking agricultural carbon intensity.
The initial focus will be on clean-fuel feedstocks. The registry will track carbon intensity scores of agricultural processes at defined stages across the supply chain from field-level origination. Each step will be timestamped and auditable.
Carbon intensity attributes will remain attached to the commodity under set chain-of-custody and mass-balance rules, rather than trade as decoupled certificates under a book-and-claim model. Each attribute will be issued against a specific quantity and geospatially defined field for a given year.
Attributes will be kept distinct from carbon credits, removals and others issued through other registries or programmes, but they can support other forms of environmental claims, for example feeding into biomethane sustainability verification.
Market participants and auditors will be able to view origin, ownership, transfer history, retirement status and claim eligibility for relevant attributes. Puro will certify that existing third-party methodologies for specific crops and use cases, including those within compliance frameworks, are implemented correctly by suppliers.
The new registry will also support companies as new obligations arise from changes to the Science Based Targets initiative (SBTi) forest, land and agriculture guidance and the Greenhouse Gas Protocol's land sector and removal standards, Puro said.
Puro's standard is among the most widely used for CO2 removal credits in the voluntary carbon market, with around 800 buyer organisations conducting transactions through its existing registry.
