UK ETS technical guidance: Monitoring and Reporting Regulation (MRR) 2018

DESNZ·guidance·LOW·5 May 2026·source document

Summary

DESNZ published updated technical guidance for UK ETS installation operators on monitoring and reporting obligations under the 2018 MRR. Covers uncertainty assessments, biomass reporting, data flow controls, and sampling requirements. No rule changes; this is compliance documentation for an existing scheme.

Why it matters

Routine compliance guidance. UK ETS is a carbon pricing mechanism that affects generator dispatch costs, but MRR technical guidance changes nothing about the price signal or allowance supply.

Key facts

  • Covers UKETS01-07 guidance documents plus VMRVP01 for waste installations
  • Relates to Monitoring and Reporting Regulation 2018
  • Includes new voluntary MRV period guidance for waste installations
