EU ETS MRV guidance updated for stationary installations
What the August and September 2026 EU ETS monitoring guidance updates mean for stationary industrial installations.

Commission guidance updated
What changed
The Commission added revised sampling guidance on 28 August 2026 and a quick guide for stationary installations on 1 September 2026.
Measure exposed hot surfaces
Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.
- Design target: surface temperature at or below 45 °C, subject to the application and design review
- Claimed heat-loss reduction: up to 96%, subject to the measured boundary and insulation specification
- Removable construction for inspection and maintenance access
- Calculation record available for the selected equipment and operating conditions
Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.

Dates and sequence
The chart separates publication dates, effective dates and actions. It does not treat a proposal as law.
- Revised sampling guidance published
- Stationary-installation quick guide published
- Apply the current approved monitoring plan and retain evidence
Risks and potential
These are implementation consequences from the cited rule. Any financial result still needs measured inputs.
Risk
An outdated monitoring or sampling method can create a data gap, require correction or increase verifier queries. Heat loss is not a separate EU ETS line item; it affects reported emissions through extra fuel use.
Potential
Calculate the emissions effect of an efficiency measure as verified fuel saved × the approved fuel emission factor. Keep the equipment survey as supporting evidence, not as a substitute for the monitoring plan.
What you need to do
- Check the current monitoring-plan version against the new stationary-installation guide.
- Review sampling plans where laboratory analysis supports activity data or factors.
- Record the source, date and uncertainty of every input used in the annual report.
