The Concerted Action supports the implementation of the RES directive. In particular, the Concerted Action facilitates sharing experience and good practice of implementation, finding common approaches as well as cross-learning and cooperation. The work carried out within the CA-RES is designed to meet the needs of RES Directive implementing organisations. The action will provide added value compared with measures taken by each MS acting on its own. The Concerted Action will help make knowledge available to all participants through access to a network of national experts engaged in implementation of the Directive. The CA-RES4 will do this through a structured framework that will facilitate the exchange of information and experience through a series of meetings and other communication tools. It will provide participants with an opportunity to learn from others implementation process and policy approaches and build national policy capacity, but also to explore opportunities for bi-lateral or multi-lateral cooperation and identify areas for possible future convergence and harmonised approaches amongst participating countries. The CA-RES4 builds upon the success and structures of the previous phases of the CA. The CA-RES community has developed during the course of the previous phases into a unique network of experts and will be strengthened. The objective is to provide participating countries with the most pertinent information that may lead them on the most efficient path towards an effective implementation of the RES Directive 2018/2001/EC in the EU. The expected impact of the Action consists of a more harmonized approach and improved implementation of the RED II in participating countries, a strengthened network of experts as well as the transfer of good practices between countries.

The objective of the 3rd Concerted Action on the Energy Efficiency Directive (CA EED3) is to foster exchange of information and experience among Member States and other participating countries (Norway) with a view to facilitating the implementation of the Directive of 2018/2002 amending Directive 2012/27/EU of the European Parliament and of the Council on energy efficiency (EED), including the implementation of the foreseen recast of this Directive . The Action follows on from the CA ESD, CA EED and CA-EED 2 which has helped MS with the interpretation of the legislation, the implementation options and support via detailed information and access to experts on mature policies and practices. The specific objectives of the Action are: • To enhance and structure the sharing of information and experiences from national implementation whilst promoting good practice concepts in activities to improve and strengthen MS implementation of the EED. • To encourage dialogue between MS on common approaches for the effective implementation of particular parts of the EED and synergies with RED and EPBD. • To complement the work of the EED Committee assisting the European Commission. The expected impact of the Action consists of a more harmonized approach and improved implementation of the EED in MS, as well as the transfer of good practices between countries and strengthened cross fertilisation with CA EPBD and CA RES. The CA EED3 brings together a unique group of experts and policy makers, it is the only informal group with full representation of all Member States and Norway and by its very nature provides MS, DG Energy and CINEA with a unique opportunity to communicate in an informal way on a technical level with relevant experts. The Concerted Action community has developed during the course of the CA ESD, CA EED and CA-EED 2 making it easy to find entry points in MS where without the Action contacts would be difficult. In turn the road is paved for bilateral cooperation.
