EU Methane Regulation compliance: MRV, LDAR and the data system behind OGMP 2.0 Level 5

Regulation (EU) 2024/1787 turns methane reporting from an estimate into a measured, verified and reconciled figure. Operators must quantify emissions source by source, add site-level measurements, run leak detection and repair surveys and end routine venting and flaring; importers must show their suppliers do equivalent work. Here is who must do what, which dates may still move, and how to build the data system that OGMP 2.0 Level 5 implies.

Who Regulation (EU) 2024/1787 applies to in oil and gas

The EU Methane Regulation entered into force in August 2024 and covers upstream exploration and production, gathering and processing, gas transmission, underground storage and LNG terminals1. It also reaches coal mining and gas distribution, which this page leaves aside; distribution networks are covered on our electric power and natural gas page.

Two groups carry obligations. Operators of EU assets must measure, report and verify methane emissions, find and repair leaks, and stop routine venting and flaring. Importers of crude oil, natural gas and coal must report on their suppliers and show that what they buy was produced under monitoring, reporting and verification (MRV) equivalent to the EU's1. The reporting logic comes from OGMP 2.0, the measurement-based framework run by the UN Environment Programme's International Methane Emissions Observatory3.

Methane obligations by role and article, with the dates that apply

Regulation (EU) 2024/1787, Article 12 (monitoring and reporting)

European Union

Applies whenYou operate, or hold interests in, upstream, transmission, storage or LNG assets in the EU.

  • Report source-level emissions quantified with at least generic emission factors by 5 August 20251.
  • For operated assets, report source-level measurement by 5 February 2026, then source-level quantification combined with site-level measurement by 5 February 2027 and every 31 May after that; non-operated assets follow later1.
  • Where source-level and site-level results differ significantly, notify the authority and reconcile them; an accredited verifier assesses every report1.

Regulation (EU) 2024/1787, Article 14 (leak detection and repair)

European Union

Applies whenAny operated site in scope, onshore or offshore.

  • Submit an LDAR programme for existing sites by 5 May 2025 and complete the first Type 2 survey by 5 August 20251.
  • Survey at the minimum frequencies in Annex I, with equipment meeting the Type 1 or Type 2 detection thresholds1.
  • Repair leaks immediately where possible, otherwise attempt repair within 5 days and complete it within 30 days, with notified exceptions where a shutdown is needed1.

Regulation (EU) 2024/1787, Article 15 (venting and flaring)

European Union

Applies whenAny operated site that vents or flares, including during start-ups and upsets.

  • Venting is prohibited except in emergencies, malfunctions and listed unavoidable cases, and routine flaring is prohibited1.
  • Flares need an auto-igniter or continuous pilot and a destruction and removal efficiency of at least 99% by design under Article 171.
  • Under Article 16, notify the authority within 48 hours of venting or flaring caused by an emergency or malfunction, or lasting 8 hours or more1.

Regulation (EU) 2024/1787, Article 27 and Article 28 (importer requirements)

European Union, reaching non-EU producers through supply contracts

Applies whenYou place crude oil, natural gas or coal produced outside the EU on the EU market.

  • Provide the supplier information in Annex IX each year by 31 May1.
  • From 1 January 2027, show that contracts concluded or renewed on or after 4 August 2024 cover only supply produced under equivalent MRV, for example OGMP 2.0 Level 5 reporting2.
  • Report the methane intensity of production from 5 August 2028, with maximum intensity values to follow by delegated act under Article 291.

US EPA NSPS OOOOb and Emission Guidelines OOOOc

United States (federal standards, with state plans for existing sources)

Applies whenNew or modified sources (OOOOb) and existing sources under state plans (OOOOc).

  • Fugitive monitoring and repair, equipment standards and venting and flaring limits were set by rules published in March 20244.
  • Deadlines were extended in 20255 and flare provisions loosened in 2026, with more reconsideration under way, so confirm dates in the Federal Register4.

Importer dates that may still move

Terms used in methane MRV and OGMP 2.0 reporting

Source-level quantification (OGMP 2.0 Level 4)
An inventory built from individual sources such as compressor seals, pneumatic controllers, tanks and fugitive components, using measurement or source-specific emission factors3.
Site-level measurement
Total emissions from a whole facility, measured from a drone, an aircraft, a vehicle or perimeter sensors, to check what the inventory may have missed.
Reconciliation (OGMP 2.0 Level 5)
Comparing source-level inventories with independent site-level measurements and investigating the differences, as an ongoing year-over-year process rather than a single comparison3.
Type 1 and Type 2 LDAR surveys
The two survey classes in Article 14, distinguished by the minimum detection threshold of the equipment; Type 2 is the more sensitive class1.

Methane measurement technologies compared for MRV and LDAR

TechnologyScaleBest used forWatch out for
Optical gas imaging camerasComponentLDAR surveys and pinpointing a leakDepends on technician skill, wind and background; rates need another method
Continuous fixed sensorsEquipment or perimeterCatching intermittent events between surveysPlacement and wind decide what they see; locating sources needs modelling
DronesSiteSite-level measurement and reaching awkward equipmentFlight permissions, weather and short endurance offshore
AircraftMany sitesScreening a portfolio for large emittersA snapshot in time with a higher detection threshold than ground methods
SatellitesBasin to large siteSpotting very large events across regionsOGMP 2.0 does not accept satellites alone as site-level technology for Level 53

Detection limits vary with instrument, altitude, wind and terrain; ask vendors for controlled-release test results.

The data pipeline behind Level 5 reconciliation

Level 5 is mostly data engineering: inventory, measurements and investigations must share the same assets and time windows.

    Every emitting component, linked to the asset hierarchy in the maintenance system.

  2. Bottom-up quantification

    Rates per source from measurements, engineering calculations and operating hours.

  3. Site-level measurement

    Facility-wide measurements stored with their uncertainty, conditions and method.

  4. Reconciliation model

    Aligns both views to one period and boundary and flags gaps beyond combined uncertainty.

  5. Root-cause investigation

    Field teams find missing sources or measurement artefacts and correct the inventory.

  6. Verified annual report

    Figures, evidence and method handed to the verifier and competent authority.

Conceptual data flow for Level 5 style reconciliation. Real systems vary by operator, asset type and measurement contractor.

Where machine learning helps in methane programmes, and where it should not decide

Three tasks suit machine learning. Plume detection models screen optical gas imaging video, aerial imagery or satellite scenes and pass candidates to an analyst. Survey prioritisation models use equipment type, age, maintenance history and past findings to suggest which components to visit first, inside the frequencies the regulation sets. Anomaly detection flags a site whose measured emissions are drifting away from its inventory.

A model should not produce the reported figure on its own. Article 12 reports are assessed by an accredited verifier1, so every figure needs a method someone can retrace: keep a named reviewer on each inventory change, and version both the model and the data it saw.

Questions and answers

What is OGMP 2.0 Level 5?

Level 5 is the highest reporting level in OGMP 2.0. It reconciles a source-level inventory, built from measured or source-specific emission rates, with independent site-level measurements of the same facilities. Differences are investigated and fed back into the inventory year after year, so it describes a continuing process rather than one survey. The Commission names Level 5 reporting as one way for producers outside the EU to show equivalent MRV2.

Does the EU Methane Regulation apply to producers outside the EU?

Not directly, because its operator duties cover assets inside the EU. Producers elsewhere feel it through their customers: importers must report supplier information every year and, for contracts concluded or renewed since August 2024, show that supply comes from producers with equivalent monitoring, reporting and verification1. In practice, EU buyers are writing requests for OGMP 2.0 Level 5 reporting or verified equivalent data into contracts.

How often are LDAR surveys required under the EU rules?

Annex I sets minimum survey frequencies that differ by component type, by location such as onshore, offshore or underground, and by survey type. Operators with consistently low leak findings can ask the competent authority to approve reduced frequencies. Build the schedule from the annex for each component class rather than one site-wide interval, and keep the evidence behind any derogation request.

What should an EU importer ask its suppliers for now?

Ask for each producer's current OGMP 2.0 reporting level by asset, the date it expects to reach Level 5, the name of its independent verifier and the methodology behind any methane intensity figure. Map every supply contract to its conclusion or renewal date, because that date decides whether full equivalence applies or only the reasonable-efforts duty for older contracts. Keep the answers in a structured supplier register.
