The agentic carbon API for your products, supply chains, and CBAM-ready reporting — government-grade data your team and your AI agents can call in milliseconds.
…plus national-inventory & government sources across 190+ more countries
Anyone can return a carbon figure. We return the figure and the audit trail behind it — on every endpoint, in the same shape. That's the difference between a number you hope is right and one you can defend to a regulator.

}Calculate, track and report carbon across spend, activity, travel and trade — with the provenance to back every number.
CO₂e from any transaction — a spend amount plus an industry code (MCC, BEA, NAICS, ISIC, SIC or NACE). Built for fintech, banking, expense and procurement.
CO₂e from physical quantities — litres of fuel, kWh of electricity, kg of material — across 1,000+ activity types, with grid factors for every country.
Great-circle flight emissions with cabin class and radiative forcing, plus road, rail, sea and air freight by mode and distance.
EU CBAM import liability: CN-code factors, default values and verified-MRV, the phase-in schedule and live carbon prices.
Discoverable and callable by AI agents over MCP, A2A and ACP — plus a clean REST API and machine-readable hints for autonomous use.
Every factor is licence-tagged and carries its methodology, source, data year, gas basis (CO₂ vs CO₂e) and GWP version (AR4 / AR5 / AR6).
The Carbon Border Adjustment Mechanism is live. Price the carbon embedded in your imports, model the phase-in, and report with audit-ready defaults — all from the same API.
The full CN-code catalogue of in-scope goods, IR (EU) 2025/2621 default values, sector benchmarks, the year-by-year phase-in schedule, and EU ETS + national carbon prices.
Per-shipment CBAM liability from a CN code, country of origin and quantity — using default values or your own verified MRV data — net of any carbon price already paid at origin. Batch a whole import ledger in one call.
Project liability across the 2026–2034 phase-in as free allocations taper, compare default vs verified-MRV scenarios, and stress-test against carbon-price and sourcing-country changes.
Your AI agent shouldn't have to click through a website. MyCO2 Suite exposes a clean menu of actions an agent can discover, understand and call in a single step — no human integration required.
