The EMRT is a web-based tool hosted by the EEA to facilitate quality checks and reviews of national emission inventories reported by EU Member States under the Monitoring Mechanism Regulation (MMR). Rules and procedures for reporting of greenhouse gas emission inventories and conducting a Union expert review are laid down in the MMR Implementing Regulation.

The EMRT was developed in 2014 under a service contract commissioned by DG Climate Action in order to streamline the procedure of recording review findings and communicating questions to Member States and replies back to the review team. From 2015 onwards the tool is used in the annual review process under the Effort Sharing Decision (ESD) and the ‘initial QA/QC checks’ under the EU GHG inventory compilation (EU QA/QC programme).
