Carbon & Climate Compliance Fit Diagnostic

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Single-node D0 diagnostic classifying which carbon/climate obligations bind a firm (CBAM authorised-declarant duty, EU Taxonomy alignment, EU Green Bond conformance, climate stress) and routing to the right Wave-16 cbm-* chain; separates in-force CBAM liability (since 1 Jan 2026) from prepare-ahead items.

Download the §4 chain definition artifact (hash-anchored composite JSON) or the §13.11 W3C Verifiable Credentials view. Both derive from the chain definition — no new hash is minted. Available after hash computation.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this whole workflow on the server and check one field that answers a real question.

Question: Our CBAM goods imports passed the annual tonnage threshold. Does the fit check flag an authorised-declarant obligation?
Run the AINumbers MCP tool `run_chain` with {"chain":"cbam-fit"} and read `art-68-carbon-compliance-fit-diagnostic.cbam_declarant_required`.
Re-run with `inputs` for `art-68-carbon-compliance-fit-diagnostic`, reusing the values that result echoed, with `imports_cbam_goods` set to "above-50t". Compare the same field.
Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`.
Ledger, for a human re-check: https://ledger.ainumbers.co/
PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
