Why methane matters more than its volume suggests, what OGMP 2.0 is, and how its five reporting levels move a company from published averages to measured reality.
Two things are worth understanding before any conversation about methane compliance: why this particular gas gets its own rules, and what the framework everyone points to actually is.
Why methane gets separate treatment
Methane is a much smaller share of emissions than carbon dioxide by volume. It gets its own frameworks, targets and now regulation for two reasons.
It is far more potent in the short term. Methane traps roughly eighty times more heat than CO2 over a twenty-year period. It also breaks down in the atmosphere far faster than CO2 does. That combination is unusual and useful: cutting methane produces a temperature benefit within a timeframe that matters politically, rather than over centuries.
It is lost product. Methane is the main component of natural gas. An emission is gas that was meant to be sold and instead went into the air. Unlike most emission reduction, capturing it produces something you can sell, which changes the economic argument considerably.
There is a third point specific to oil and gas operations, and it is the one that makes measurement difficult. Flaring is not the same as methane emission. A flare burning properly converts methane to CO2, which is the intended outcome. A flare burning badly, or one that has gone out and is venting raw gas, emits methane directly. The same piece of equipment can be a mitigation or a major source depending on whether it is working, and you cannot tell from a distance.
What OGMP 2.0 is
The Oil and Gas Methane Partnership 2.0 is run by the United Nations Environment Programme through its International Methane Emissions Observatory.
It is the only measurement-based international methane reporting framework for the sector. That word is doing the work: other frameworks accept estimation, and OGMP is built around progressively replacing estimates with measurements.
Membership is voluntary. What has changed is the consequence of not being in it. Because the European Commission points to OGMP 2.0 as the practical route to demonstrating equivalence under its import regime, the framework has quietly become market infrastructure rather than a reporting choice. The Commission notes that OGMP 2.0 already covers around 42% of global oil and gas production.
Reporting is technology neutral. OGMP specifies the standard of evidence at each level, not the instrument. An operator chooses the approach that suits its assets.
The five levels, in plain terms
The framework’s core is a ladder from estimated to measured.
| Level | In plain terms |
|---|---|
| 1 | One number for the whole venture or asset |
| 2 | Broken down by emissions category, using published industry factors |
| 3 | Published factors applied at detailed source type level |
| 4 | Detailed source types, using your own methods and measurement |
| 5 | Level 4 checked against independent measurement of the whole site |
Levels 1 to 3 are desk exercises. You take published emission factors, apply them to equipment counts and throughput, and produce a total. Nobody visits the asset. A competent team can produce Level 3 from records that already exist.
Level 4 is where you go and measure. Company-specific methods means quantifying what your equipment actually emits, not what the industry average says it should.
Level 5 adds an independent check. Someone measures the whole site by a completely different method, and the two figures are reconciled statistically, with an uncertainty analysis on both.
The detail of each level and what the measurement physically involves are covered separately.
Why the ladder exists at all
Because generic factors are frequently wrong, and wrong in an unhelpful direction.
Real assets do not behave like industry averages. Emissions in practice tend to concentrate in a small number of large sources, often unexpected ones: a failed seal, a stuck valve, an unlit flare. An estimated inventory spreads the total evenly across the equipment count and therefore misses exactly the thing that matters.
That is why measurement changes the picture rather than confirming it, and why first measured inventories routinely look worse than the estimated ones they replace. That is the system working correctly, not a failure.
The recognised statuses
Two are worth knowing.
Gold Standard Reporting comes at year three, when all material operated assets report at Level 4 or 5, and at year five for non-operated assets.
Gold Standard Pathway is available earlier, on the strength of a compliant report, a granular per-asset plan showing the route to Level 4 or 5, and a methane reduction target. A new member can hold it in year one, before any measurement campaign completes. For a producer facing a near-term buyer requirement that is usually the achievable position, and we cover it in Gold Standard Pathway.
Annual reporting is due by 31 May, covering the previous calendar year.
What to take away
- Methane matters disproportionately to its volume, and fixing it produces saleable product.
- OGMP 2.0 is the measurement-based framework the EU regime points to.
- The five levels move from estimated to measured, and the jump from 3 to 4 is where cost and time appear.
- Membership is voluntary; market access increasingly is not.
How ESGweise helps
We build methane-specific greenhouse gas inventories, take operators through OGMP 2.0 implementation and annual reporting, and design the data architecture that carries it. Physical measurement is delivered with specialist partners and verification sits with an independent body. See our carbon and sustainability reporting services, and our oil and gas practice.

Frequently asked questions
Why does methane matter so much if there is far less of it than CO2?
Because of its potency and its timing. Methane traps roughly eighty times more heat than carbon dioxide over a twenty-year period, though it breaks down in the atmosphere much faster. That means reducing methane delivers a temperature benefit sooner than almost any other available action, which is why it attracts separate targets, separate frameworks and now separate regulation.
What is OGMP 2.0?
The Oil and Gas Methane Partnership 2.0, run by the United Nations Environment Programme through its International Methane Emissions Observatory. It is the only measurement-based international methane reporting framework for the oil and gas sector. Membership is voluntary, but the European Commission points to it as the practical route to demonstrating the equivalence its import regime requires, so it increasingly functions as market infrastructure.
Is OGMP 2.0 mandatory?
No. It is a voluntary framework and no one is obliged to join. What has changed is the consequence of not being in it. Because the EU import regime names OGMP 2.0 Level 5 with verification as a route to equivalence, a producer selling into Europe on new or renewed contracts needs either that or a jurisdiction-level equivalence arrangement.
Does OGMP 2.0 require particular equipment?
No. OGMP 2.0 reporting is technology neutral. It specifies the standard of evidence required at each level, not the instrument used to produce it. That leaves an operator free to choose the measurement approach that suits its assets, and prevents the framework from locking members into a single vendor or technique.
