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.
