Methane reporting is moving from "detection-only" toward "regulatory-defensible," meaning operators need to prove their numbers, not just estimate them. OGMP 2.0 is the framework driving that shift.
Launched by UNEP and the Climate and Clean Air Coalition, OGMP 2.0 is the flagship measurement-based methane reporting standard for oil and gas. It's growing more relevant to US operators as measurement-based reporting expectations spread.
This article breaks down the framework's five reporting levels, the path to Gold Standard, common implementation hurdles, and how continuous monitoring technology closes the measurement gap.
Key Takeaways
- OGMP 2.0 is the only comprehensive, measurement-based methane framework for oil and gas, built by UNEP and CCAC
- Level 4/5 reporting requires source- and site-level direct measurement, not generic emission factors
- Gold Standard requires Level 4/5 within 3 years for operated assets and 5 years for non-operated assets
- More than 150 companies covering roughly 45% of global oil and gas production now report under the framework
- Continuous multi-sensor monitoring is a practical path to Level 4/5 without relying on costly quarterly-only LDAR programs
What Is OGMP 2.0 and Why It Matters for US Operators
OGMP 2.0 launched in November 2020 through a partnership between UNEP, CCAC, the European Commission, and 62 founding oil and gas companies. It sits alongside the UN's International Methane Emissions Observatory (IMEO), which uses OGMP company data as one of its core inputs for empirically verified emissions tracking.
The framework has also shaped the EU Methane Regulation's measurement-reporting-verification (MRV) requirements and now serves as a template for emerging global methane rules.
Scope covers all Scope 1 methane sources, not only the original nine core categories. Common source types include:
- Venting
- Fugitive emissions
- Incomplete combustion
Reporting also extends across operated and non-operated ventures, so equity partners share the same measurement expectations as operators.
OGMP 2.0 is a voluntary reporting framework and is formally separate from US federal regulation. More than 150 companies with assets in over 90 countries now participate, representing close to half of global production.
An exact count of US-headquartered members is not broken out publicly, but participation is rising among producers building measurement-based reporting capability ahead of investor and customer expectations.
Understanding the Five OGMP 2.0 Reporting Levels
The framework's structure is straightforward on paper, brutal in practice. Each level demands more granular, defensible data than the last.
Levels 1-3: Starting Points, Not End States
- Level 1-2: Country or asset-level estimates using generic factors. Fine for a first report. Useless for defensibility.
- Level 3: Detailed source-type reporting using generic emission factors, similar in spirit to EPA Subpart W methodology. More granular than Levels 1-2, but generic factors still tend to underestimate actual field emissions.
Levels 4-5: Where Measurement Becomes Real
Level 4 requires source-level, asset-specific measurement: direct measurement, engineering calculations, or simulation, rather than a plug-in emission factor.
Level 5 adds independent site-level measurement and reconciles it against the Level 4 inventory. This isn't a one-time sanity check. It's an ongoing reconciliation process that keeps refining the source-level numbers as new site data comes in.
Counterintuitive result: methane intensity often rises when operators move from Level 3 to Level 4/5 reporting. Measurement-based reporting programs have documented this "u-curve" pattern: reported intensity falls from Level 2 through Level 3, then climbs again at Level 4 and Level 5 as previously invisible sources get uncovered.
Operations didn't get worse. Measurement got better.
That distinction matters for anyone presenting Level 4/5 numbers internally or to investors: an increase in reported emissions can signal improved accuracy, not declining performance.
The Path to Gold Standard: Timelines and Implementation Plans
Gold Standard status is OGMP 2.0's top designation, and it's awarded annually, not once and done.
The core requirement: reach Level 4/5 reporting for material assets (those making up the top 95% of total operator emissions) within:
- 3 years for operated assets
- 5 years for non-operated assets
At the asset level, Level 4 reporting must cover sources responsible for at least 70% of methane emissions, with justification required if coverage falls below 90%.
Meeting those deadlines starts with a formal Implementation Plan.
What the Implementation Plan Needs
UNEP's Implementation Plan Template requires operators to document:
- A complete operated and non-operated asset list, with exclusions justified
- Baseline year and Gold Standard target date
- Per-asset materiality, current reporting level, and Level 4 approach
- Technology, methods, and uncertainty for measurement
- Level 4/5 reconciliation timeframe and findings
- Emissions reduction targets and mitigation plans
A Realistic Phased Approach
For operated assets on the three-year clock, a practical sequence looks like this:
- Year 1: Identify sources, build the inventory, pilot measurement technology on high-priority assets
- Year 2: Expand deployment, formalize data pipelines, begin reconciling Level 4 and Level 5 data
- Year 3: Full reconciliation, audit-ready reporting, Gold Standard submission
The Non-Operated Asset Problem
Joint ventures create the hardest reporting gaps. When a non-operating partner will not modify systems or share data, OGMP 2.0 applies a "reasonable and demonstrable effort" standard. Gold Standard is not automatically lost if the reporting company documents genuine attempts to obtain the data and reports what it has.
Common Challenges Operators Face and How to Navigate Them
Getting to Level 4/5 sounds simple. Building the underlying infrastructure isn't.
Building a complete source inventory. Most operators start with P&IDs, flow diagrams, and equipment lists — but these documents often lag behind actual field configurations, especially at older sites. A field study covering 39 sites in the Marcellus, Haynesville, and Permian found that bottom-up inventories consistently missed emissions sources that top-down measurement caught. Ground-truth desktop inventories with site-level measurement before you freeze Level 4 source lists.
Technology deployment across remote, multi-site operations. Onshore portfolios spread across hundreds of wellsites face:
- Intermittent connectivity limiting real-time data transmission
- Inconsistent power availability at remote pad sites
- Difficulty standardizing measurement across varied equipment ages and configurations
Navigate this with edge-capable monitoring that stores and processes data onsite, so gaps in backhaul do not create gaps in the record. Standardize on a common data model across pads even when equipment vintages differ.
Reconciling data across measurement modalities. Drones, satellites, and continuous ground sensors all measure differently, at different scales and cadences. The same field study combined continuous monitoring systems, drone mass-balance readings, aerial LiDAR, and optical gas imaging, the cross-modality work Level 5 requires.
Use continuous site-level data as the reconciliation anchor, then layer aerial and satellite reads for spatial coverage. Validated technology matched to each source type is what keeps Level 5 figures defensible under audit.
How Continuous Multi-Sensor Monitoring Closes the Level 4/5 Gap
Quarterly LDAR inspections produce a snapshot. A leak that starts on day two of a 90-day cycle runs undetected for weeks, and there is no way to reconstruct how much methane escaped or for how long. That is the gap Level 4/5 reporting is built to eliminate.
Well Checked's Zensory.ai™ platform is built for that gap. It combines high-resolution video, Long-Wave Infrared optical gas imaging, and acoustic AI in one continuous monitoring system that feeds measurement-based reporting instead of periodic spot checks.
A Three-Tier Structure That Mirrors OGMP 2.0's Logic
The platform's architecture maps closely to what Level 4/5 actually demands: validated quantification, not raw alerting.
- Zentinal Ops™ — Baseline visual and acoustic site intelligence
- Zentinal Core™ — Fuses video, LWIR OGI, and acoustic data; learns a site baseline in about two days and alerts only on true fugitive anomalies
- Zentinal IQ™ — Quantifies validated events by volume, duration, and rate after Core confirms a true event
That validation-first sequence matters. Reporting bodies and regulators alike want confidence that a number represents a real measured event, not statistical noise.
One Platform, Multiple Reporting Uses
Zentinal IQ output is structured for EPA's OOOOb alternative-monitoring pathway, OGMP 2.0 Level 4/5 formats, and SASB/TCFD disclosure needs. Operators do not need separate systems for each framework. The same quantified event data (volume, duration, rate) can support multiple compliance and disclosure obligations.
Well Checked currently monitors remote US onshore sites, including a confirmed continuous monitoring in the Appalachian Basin for a large Appalachian operator.
Continuous data also sharpens repair-and-maintenance ROI. Duration and volume figures show which leak to fix first and why, so operators can put a $1M-plus annual route-based inspection budget against prioritized work instead of fixed routes alone.
Frequently Asked Questions
Is OGMP 2.0 mandatory for US oil and gas operators?
No. It's a voluntary UN-led initiative. Growing regulatory alignment, including its influence on the EU Methane Regulation and emerging MMRV standards, still makes early participation strategically valuable for operators.
What is the difference between OGMP 2.0 Level 4 and Level 5 reporting?
Level 4 is source-level measurement-based inventory using direct measurement or engineering methods. Level 5 adds independent site-level measurement and reconciles it against that Level 4 inventory on an ongoing basis.
How long does it take to reach OGMP 2.0 Gold Standard?
Three years for operated assets, five years for non-operated assets, measured from formal membership. Most companies use a phased implementation plan to get there.
Can a company lose Gold Standard status if joint venture partners won't share data?
Not automatically. OGMP 2.0's "reasonable and demonstrable effort" provision protects Gold Standard status if the company documents genuine attempts to obtain non-operated asset data.
What technologies are used for OGMP 2.0 Level 4/5 measurement?
OGMP 2.0 is technology-agnostic. Common options include optical gas imaging, continuous sensors, drones, satellites, and acoustic detection. All require validation for accuracy.
Does OGMP 2.0 reporting help with EPA methane rule compliance?
Yes, indirectly. Measurement-based OGMP 2.0 data structures align well with the alternative-monitoring provisions under EPA's 40 CFR Part 60 Subpart OOOOb, though the two frameworks remain formally separate.
