Oil, gas, and energy

How do you report Scope 1, 2, and 3 emissions you can actually defend?

Most of an oil and gas footprint sits in Scope 3, and the methane numbers depend entirely on how they were measured.

Why a once-a-year rollup no longer holds

Disclosure has moved from voluntary to expected across the major frameworks, and the scrutiny is on method as much as on the total.

Under the GHG Protocol, Scope 1 covers direct emissions including methane from venting and flaring, Scope 2 covers purchased energy, and Scope 3 covers the value chain, which for the combustion of sold fuels often dominates the total. A manual annual estimate will not survive an audit.

Emissions are a data problem before a reporting problem

Defensible numbers come from activity data captured at source: fuel consumed, volumes produced, flare and vent logs, procurement records.

Tonnes of CO2e are only as trustworthy as the meter and the method behind them, with methane converted by its global warming potential. How it was measured is now part of what is reviewed.

Where the ERP closes the loop

On Hudace, carbon accounting pulls from the same operational records as production and procurement, so a reported figure traces back to the transaction that produced it.

Xenon AI flags anomalies, a leak signature, a gap in the data, and fills estimation gaps with a method you can show an auditor. A person approves what is filed.

The numbers to watch

Track not just the totals but the quality of the data behind them.

Scope 1 / 2 / 3

Emissions in tonnes of CO2e by scope. Leaving Scope 3 out understates the footprint for sold fuels.

Methane intensity

Methane emissions per unit of production. A focus area given methane's high global warming potential.

Measured vs estimated

Share of emissions from direct measurement rather than estimate. Higher is more defensible.

Data completeness

Share of activity data captured at source. The foundation an auditor checks first.
