The monitoring and reporting of greenhouse gas emissions must be robust, transparent, consistent and accurate for the EU emissions trading system (EU ETS) to operate effectively.
The annual procedure of monitoring, reporting and verification (MRV), together with all the associated processes, is known as the ETS compliance cycle.
Industrial installations and aircraft operators covered by the EU ETS are required to have an approved monitoring plan for monitoring and reporting annual emissions. This plan is also part of the permit to operate required for industrial installations.
Every year, operators must submit an emissions report. The data for a given year must be verified by an accredited verifier by 31 March of the following year. Once verified, operators must surrender the equivalent number of allowances by 30 April of that year.
The rules related to the compliance cycle are set out in two regulations:
To promote administrative efficiency and a harmonised approach across countries, the European Commission provides templates as the basis for
Guidance, exemplars and further tools are also published to support correct understanding of the requirements of the regulations as well as promote more harmonised and cost-effective application throughout all ETS countries.

Additional tools and guidance have been developed for aviation operators.
