Methane Regulation (EU) 2024/1787
LDAR surveys, repair deadlines, measurement & reporting

Methane leaks are no longer an estimate. Regulation (EU) 2024/1787 fixes survey frequencies, detection thresholds and repair deadlines — and requires source- and site-level measurement in the reports.

What the rule requires

Article references are to the text in the Official Journal; summaries are informational, not legal advice.

LDAR programme — Art. 14(1)Written programme with survey types, timelines and methods; updated when changed.
Survey frequencies — Annex I Part 1Type 1 surveys: compressor stations, underground storage, LNG facilities, regulating & metering stations every 4 months; valve stations every 9 months. Type 2: 8 and 18 months. Distribution/transmission networks: by material — e.g. grey cast iron / bitumen sheet every 3 months (type 1), protected steel / PE / PVC every 15–24 months.
Detection thresholds — Art. 14(8)Type 1: 7 000 ppmv CH₄ or 17 g/h. Type 2: 500 ppmv or 1 g/h for aboveground components (1 000 ppmv / 5 g/h for the second step on underground components; 7 000 ppmv / 17 g/h offshore below sea level).
Repair deadlines — Art. 14(9)Repair or replacement immediately after detection; if not possible, first attempt no later than 5 days and completion within 30 days after detection. Delays must be notified with evidence and a repair & monitoring schedule (Annex II) within 12 days.
Measurement & reporting — Art. 12Source-level quantification, then site-level measurements to reconcile the source-level estimates; reports verified by an independent verifier (Art. 8).
Venting & flaring — Art. 15–17Venting and routine flaring prohibited except in defined situations; events above thresholds reported.
What you have to measure
  • CH₄ concentration at components (ppm) against the 500 / 1 000 / 7 000 ppmv thresholds — handheld or continuous
  • CH₄ mass rate (g/h) for quantification and the repair decision
  • Continuous CH₄ at compressor and metering stations for site-level reconciliation
  • CH₄ + CO₂ of biomethane at the grid injection point (composition, not just leaks)
// Missed survey frequencies or repair deadlines are infringements under national penalty regimes (Art. 33); unverified reports are rejected by the verifier; from 2027 importers must document producers' measurement practice (Annex IX).
What we are building for this rule

Continuous, self-locating methane detection — the gap between a scheduled handheld survey and what the rule will demand.

Between surveys, a leak stays invisible. We are building a plant-wide mesh of chip-scale laser nodes that watches every component continuously and names the leaking joint — hands-free, with a continuous record for MRV/LDAR reporting. The laser chip is in development; we do not sell this system yet.

Questions engineers ask
Does the Regulation prescribe the detection technology?
No. It sets thresholds in ppmv or g/h and refers to standards to be established under Art. 32; until then 'state-of-the-art industry practices and the best technologies that are commercially available' apply (Art. 14(1)).
Where does continuous, self-locating detection fit?
The rule fixes survey frequencies and thresholds — but between scheduled surveys, a leak stays invisible. A continuous, plant-wide mesh that locates and names the leaking component is what closes that gap, and it is exactly what we are building. It is R&D in development; we do not sell this system yet.
Is this only for big operators?
It applies to all operators of assets in scope (production, gathering, processing, transmission, distribution, storage, LNG) regardless of size; only frequencies differ by component and material.
