The Effort Sharing Decision (ESD) sets national emission targets for Member States for each year between 2013 and 2020 in the sectors of the economy not covered by the EU Emissions Trading System. To ensure that compliance with these targets is assessed in a credible, consistent, transparent and timely manner, a Union review of Member States' greenhouse gas inventories takes place every year. The review is carried out by the technical expert review team contracted by the Commission, and coordinated by a secretariat at the European Environment Agency. The final review reports can be found in the Documentation section.
The Documentation section also contains for each year a Commission Implementing Decision, in which the final ESD emissions per Member State are determined, after taking into consideration the technical corrections and revised estimates calculated during the review. After the publication of this Decision in the Official Journal, Member States have four months for applying flexibilities under Articles 3 and 5 of the ESD (borrowing or buying allocations/international project credits) to ensure annual compliance with their ESD targets.
Under the ESD Member States can decide which national policies and measures they implement to limit emissions from the Effort Sharing sectors. The Commission enforces Member States' compliance with the ESD. So far the Commission has checked compliance with ESD targets for the years 2013-2015 with the conclusion that all 28 Member States complied with their ESD targets: Each year, 27 Member States managed to limit their emissions domestically, while one Member State covered its surplus emissions by purchasing allocations from another Member State that had overachieved its emission targets for the years 2013-2015 (see details). So far, no Clean Development Mechanism or Joint Implementation credits have been used for compliance with the ESD. Information on compliance and the use of flexibilities by Member States is updated daily at the EUTL public website.
The Commission also assesses progress made by the Member States toward their ESD targets, in the annual progress report published every autumn. Moreover, in 2014 the Commission organized a series of workshops for regional clusters of Member States to develop capacity and to share best practice and ideas on approaches to reducing greenhouse gas emissions under the Effort Sharing Decision. While the workshop in Sofia covered the sectors buildings and transport, the workshops in Tallinn, Warsaw and Madrid covered the sectors transport and agriculture (see presentations at the Documentation section).
In July 2016, the Commission presented an evaluation of the implementation of the legislation up to 2015. The evaluation concluded that:
The results of the evaluation were used when preparing the proposal for continuing effort sharing legislation from 2021 to 2030.
