Comparison
CBAM Data vs Climatiq
A carbon calculation API across many activities. Its CBAM endpoint turns CN code, production region and weight into direct and indirect emissions.
| Evaluation criterion | Climatiq | CBAM Data |
|---|---|---|
| Official default values | Uses EU default and region-specific emission factors for CBAM categories, with an audit trail (climatiq.io/cbam, read 16 Sep 2026). Primary supplier data is announced as coming soon. | Bundles official European Commission default values (Reg (EU) 2025/2621 as corrected by Reg (EU) 2026/1740) with automatic statutory markups (10% to 30%) and sector routing. |
| CBAM certificate price | Its CBAM page says it helps customers understand certificate costs. It does not state which published certificate price or period a result uses. | Tracks official European Commission published quarterly prices (weekly from 2027) based on EEX auction averages, integrated directly into certificate cost estimates. |
| Regulatory change feed | Versions its emission factor datasets. Its CBAM page describes no feed of changes to the Commission's default values, prices or scope. | Emits cryptographic diffs generated on every official data ingest, published as pages, feeds, and email alerts. |
| Phase-in and deduction rules | Returns embedded emissions. Its CBAM page does not describe the CBAM factor by year, the default value mark-up or Art. 9 deductions. | Applies the Art. 31 free allocation adjustment (the CBAM factor, 97.5% in 2026 to 0% in 2034, times the Reg (EU) 2025/2620 benchmark) and Art. 9 origin carbon price deduction formulas in pure code. |
| System integration | Platform-agnostic REST API on a global edge network, with full documentation, built for calculations across many emission categories. | Sub-millisecond REST API (/v1/resolve), OpenAPI 3.1 specification, and Model Context Protocol (MCP) server for automated customs systems. |
| Pricing structure | Data access starting from €250/month or metered by calculation volume. | Fixed monthly subscription (€99 Importer, €199 Developer) with included calls and no per-request metering or unexpected overage bills. |
Our recommendation
Climatiq serves organizations calculating broad greenhouse gas emissions across corporate supply chains. When you need automated European Union CBAM compliance (official Annex I default values, statutory markups, weekly certificate prices, and CBAM factors and benchmarks by year), CBAM Data gives you dedicated endpoints built for customs workflows.
Keep every import line on the current rule.
One call returns the scope, certificates, euro cost and filing date for a CN code. When the Commission changes a value, a webhook tells your system.
