Methane Emissions Reduction and Intensity Tiers
A verified methane intensity for behind-the-meter datacenters
MERIT certifies on-site gas generation across the whole chain: basin-traced supply, combustion slip and steady state, and continuous leak detection across the plant.
The scale
End-to-end total methane intensity per MWh
- Diamond<0.2%
- Gold0.2–0.7%
- Silver0.7–1.5%
- Improved1.5–3.5%
- Business As Usual>3.5%
Thresholds are set and regularly reviewed by a technical committee
Why now
Data center developers have announced over 100 GW of behind-the-meter power plants
This is over two times California’s entire gas-fired fleet of 39 GW. Design decisions today will determine decades of future methane emissions.
7.4%
of the methane escaped to the atmosphere in one datacenter design analysis
2x
Those methane leaks doubled the datacenter's GHG footprint, using the 100 year time horizon (GWP100).
3x
Per GWP20 (20-year time horizon) for GHG accounting, the methane leaks more than tripled the datacenter's GHG footprint
These emissions are avoidable for less than 1% of the cost of the datacenter
Fixing these will not delay when the compute comes online. MERIT was created because datacenter builders can make these design changes now and should get credit for doing so.
Multipliers compare combustion CO2 plus escaped methane with combustion CO2 alone, using IPCC AR6 global warming potentials for fossil methane (29.8 over 100 years, 82.5 over 20).

Scope
End-to-end analysis from wellhead to GPU
Most reporting stops at the fence line of the generating plant or uses a national average for all upstream sources. In contrast, MERIT is a complete measurement.
01 · Upstream
Wellhead
Leakage traced to specific gas wellheads
Typical loss
0.1% to >4.5%
02 · Midstream
Gathering & processing
Leaks in transport from wellhead to processing plant
Typical loss
Up to 3%
03
Transmission
Not traced: actual loss is negligible
04
Engine Methane Slip
Gas that passes through the engines without burning and leaves through the exhaust
Typical loss
0.1% to 3%
of fuel burned: turbines at the low end, lean-burn engines at the high end.
05
Plant leaks
Loss via valves, flanges, seals and/or tanks at the generation facility
Typical loss
Not well studied
Existing numbers from utility-scale plants differ significantly from new datacenter plants
Delivered Power Score:
Net MWh delivered, inclusive of parasitic load and curtailment (rather than nameplate output)
Loss ranges: Alvarez et al. 2018, Science (US averages); Omara et al. 2018, Environmental Science & Technology (well sites by basin); Omara et al. 2022, Nature Communications (US well-site average and low-output wells); Sherwin et al. 2024, Nature (aerial survey of US oil and gas regions); Mitchell et al. 2015, Environmental Science & Technology (gathering and processing sites); Hajny et al. 2019, Environmental Science & Technology (gas-fired power plants); US EPA AP-42 §3.2 (reciprocating engines).
Recognition
MERIT recognizes existing certifications
MERIT rules are designed for new behind-the-meter datacenter usage scenarios, as upstream methane accounting has taken years of contested work and is already in the field. For the highest tiers, MERIT adds direct measurement where requirements do not exist by current recognized standards.
Areas of verification
Annual audits generally cover six areas:
1 • Traced supply
Certificates or contracts establishing gas origination sources, compared volumetrically vs what the plant burned.
2 • Combustion slip, including ramps
Slip tested across the load range weighted by real operating hours - reciprocating fleets are measured across real load ranges.
3 • Plant leak detection
Continuous monitoring or regular camera surveys of the plant.
4 • Energy balance
Gas consumed against power generated for real efficiency metrics
5 • Annual certification
Certificate covers one reporting year and lapses without a new audit.
6 • Offsets
Residual emissions may be offset and can improve a tier. Measured intensity and offset volume are included in the certification for full transparency.
Independence
MERIT does not sell gas, equipment, or offsets
The Coalition
Rules are drafted by a coalition of operators, power developers, gas suppliers, academic experts, and measurement specialists.
MERIT
Reviews evidence against the standard; grants, suspends and withdraws certification.
MERIT's audit team
Carries out site audits and measurement review in the first cycle.
Verification
Direct verification by MERIT
Initial verifications will be done directly by MERIT's auditing team. Later versions of this standard may opening verification to accredited third parties.
For operators
Run the numbers before the plant is built
Design review can optimize final intensity before unit selection, supply contracting, and monitoring layout are locked in.
