Energy AI agent · Emissions data certification

Emissions Data Certification AI Agent

Trace every reported figure back to the meter, monitor or invoice behind it, with the factor version it used, and hold the report for the designated representative who certifies under penalty of law.

What this agent does

Assembles the figures, not the certification

In
01

A monitor goes out of control, and the quality-assurance status of the value goes on the record with it.

02

A gap opens in monitoring data, and the substitute value reaches the report marked as substituted.

Reason
03

A quarter closes, and 40 CFR 75.64 allows 30 days and a computer-to-computer transfer.

04

A unit carries add-on controls, and its substitutes must not systematically underestimate.

05

A factor set is revised, and every figure carries the factor version and the period it applies to.

Decide
06

An annual report falls due, and 98.3(b)(6) moved reporting year 2025 to 30 October 2026.

07

A representative changes, and the requirement sits in 40 CFR 72.20, not the monitoring part.

Out
08

A repeal is proposed, and 90 FR 44591 was still only proposed on 23 August 2026.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

The agent assembles and reconciles. The named person is the designated representative — one individual, who certifies under penalty of law and submits.

Example workflow

One value, meter to certification

AgentHuman
1Value evidence receivedMeter readings, fuel invoices, monitor records or factor sets
2Value provenance assembledThe unit, the monitor behind it, the factor version applied and the period it covers
3Report assembledThe values, their sources, the substitutions and completeness
4Controls appliedProvenance checks, quality-assurance checks, factor checks and completeness confidence
No human action required

Stages 1 to 4 run unaided, and nothing is certified at any of them — the agent is assembling, and the compliance lane opens at the completeness gate.

5DecisionDivides at the completeness gate
Provenance complete

Goes to the designated representative to certify.

Anything substituted

Adds an environmental engineer read first.

Compliance review

The report is held with its values, its substitutions and the units they sit on.

Certify and submit · Append evidence · Send to review

7Outcome evaluatedProvenance completeness, substitution rate, engineer corrections and what review found
Corrections

Each engineer correction is counted in the evaluation.

Example output

One value, annotated

Our sustainability reporting copilot applies your framework mapping; the same meter reading feeds this report, and only this one carries a prison term.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every valueFrom the monitor that produced it
03Provenance

Where the report is used

Our compliance reporting assistant assembles a register and names no regime; this page is one statute, with one deadline and one named individual.

01Approved path

One person, personally examined

40 CFR 98.4(b) wants an individual, selected by an agreement binding on the owners and operators; a corporation cannot serve.

02Human review

What was checked, and what was not

The September 2025 reconsideration was still a proposal on 23 August 2026, checked three ways; one state adopted mandatory reporting against that rollback.

04Build an evidence trail

The value, the monitor it came from and the representative who certified stay on the report.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

How Nestack evaluates it

Evaluate the whole assembly — not only the report that comes out.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — the report a representative certifies
Depth of coverage ▼
E1Final-output evaluationDid the report carry the source behind every value?
E2Step-level evaluationDid the agent read the right unit, the right monitor and the live factor set?
E3Tool evaluationDid it read and write the correct unit record and the correct period?
E4Confidence calibrationDo low-confidence reports actually attract more engineer corrections?
E5Slice evaluationHow does performance change across specific unit types?
E6Business outcomeHow many reports needed a correction before the representative certified?
Floor — the outcome the owners and operators answer for

Affected slices

Substitute data absorbs the corrections

A unit-level value-provenance figure can read clean while units on substitute data carry most of the corrections. Nestack reports the correction rate by unit type, not only in total.

Evidence-linked improvement

What an unexplained substitute costs

A cycle ends when the unexplained substitute value is a standing case. That suite is what the next report assembled is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Correction rate rises on units running substitute data.

02Diagnose

The hour of missing monitor data that nobody could explain nine months on is read back until one cause remains.

03Improve

Changes leave numbered, and the values behind them travel attached.

04Verify

A single failing value case is enough to stop the release.

05Learn

The case is kept, and the substitution rules are rewritten alongside it.

Learn → DetectThe return edge. The next report is measured against a suite one case longer.

Next step · Energy AI agent

Build an emissions data agent around the values one person has to personally examine.

Show us one reported figure and the monitor behind it. Not a framework workpaper. A statutory report certified under penalty of law, due 30 October 2026 under 98.3(b)(6). Site permit conditions and deviation reports are a different agent.
