Company Overview

About CarbonChain

CarbonChain is a London-based climate technology company providing AI-powered carbon accounting and emissions tracking for carbon-intensive supply chains — serving metals, mining, and commodities sectors (steel, aluminum, copper, agriculture) with granular, asset-level emissions data that enables companies to measure Scope 3 supply chain emissions with the precision that financial institutions, regulators, and corporate sustainability commitments require. Founded in 2017 and backed by Y Combinator with $24.2 million raised, CarbonChain serves major enterprises including thyssenkrupp, Société Générale, and Rabobank.

Business Model & Competitive Advantage

CarbonChain's asset-level emissions database covers the emissions intensity of individual production facilities globally — smelters, mines, refineries, and manufacturing plants — providing the granularity needed for supplier selection decisions and portfolio carbon risk assessment. This facility-level data enables financiers to assess the carbon risk in commodity trade finance portfolios and manufacturers to select lower-carbon raw material suppliers. The EU Carbon Border Adjustment Mechanism (CBAM) compliance module directly addresses the EU's new carbon tariff on imports of steel, aluminum, cement, fertilizers, and other carbon-intensive goods.

Competitive Landscape 2025–2026

In 2025, CarbonChain competes in the industrial carbon accounting and supply chain emissions market with South Pole (sustainability consulting), Watershed (enterprise carbon accounting, raised $100M+), Persefoni (financial sector carbon accounting), and MSCI (ESG data) for corporate and financial institution carbon measurement. The CBAM regulations (fully implemented by 2026) require importers of carbon-intensive goods to report embedded emissions — creating mandatory data demand for exactly the kind of asset-level facility emissions database that CarbonChain has built. Société Générale and Rabobank as customers validate the financial sector use case (commodity trade finance carbon assessment). The 2025 strategy focuses on CBAM compliance services for European importers, growing the financial institution supply chain finance carbon risk assessment product, and expanding the asset-level emissions database to more commodity categories.
