CarbonChain

CarbonChain is a London- and New York-based carbon accounting platform founded in 2019 that is purpose-built for the highest-emitting, hardest-to- track commodity supply chains — metals and mining, energy, manufacturing, and agriculture. Its AI-assisted platform builds asset- and transaction- level emissions pictures using activity-based emission factors, and packages those calculations into modules for supply-chain emissions, corporate carbon footprints (Scope 1, 2, 3), product carbon footprints, scenario analysis, and regulatory compliance. The flagship CarbonChain Comply release ships a Carbon Reporting Hub aligned with EU CSRD, UK SECR, US SEC, and CDP, along with EU/UK CBAM declaration validation, automated CBAM XML generation, and a Supplier Engagement Module for collecting and validating supplier emissions data. CarbonChain Connect links producers and importers through shared installation-level CBAM infrastructure. The company is a CDP Accredited Provider (2024), is ISO 27001 certified, and is backed by Y Combinator, Union Square Ventures, Voyager VC, and Aera VC, with $10M Series A funding (2023). CarbonChain serves manufacturers, commodity traders, banks, and procurement teams, and offers system-to-system API integration for delivering activity data in and pulling gold-standard emissions calculations out — but it does not publish a public developer portal, OpenAPI specification, SDK, or open-source client library. API access is offered as part of customer integration projects rather than as a self-serve developer surface.

CarbonChain is profiled on the APIs.io network. Tagged areas include Carbon Accounting, Emissions Tracking, Supply Chain, Heavy Industry, and Commodities.

CarbonChain’s developer surface includes engineering blog, GitHub presence, and 10 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/carbonchain: open an issue to ask a question, or submit a pull request to add artifacts.
