Regulation (EU) 2018/1999 of the European Parliament and of the Council on the Governance of the Energy Union and Climate Action.

This Regulation establishes a governance mechanism to: (a) implement strategies and measures designed to meet the objectives and targets of the Energy Union and the longterm European Union greenhouse gas emissions commitments consistent with the Paris Agreement, and for the first ten-year period, from 2021 to 2030, in particular the Union's 2030 targets for energy and climate; (b) stimulate cooperation between Member States, including, where appropriate, at regional level, designed to achieve the objectives and targets of the Energy Union; (c) ensure the timeliness, transparency, accuracy, consistency, comparability and completeness of reporting by the Union and its Member States to the UNFCCC and Paris Agreement Secretariat.
The governance mechanism is based on long-term strategies, integrated national energy and climate plans covering ten year periods starting from 2021 to 2030, corresponding to integrated national energy and climate progress reports by the Member States and integrated monitoring arrangements by the Commission. The governance mechanism ensures effective opportunities for the public to participate in the preparation of those national plans and those long-term strategies. It comprises a structured, transparent, interactive process between the Commission and Member States for the purpose of the finalization of the integrated national energy and climate plans and their subsequent implementation, including with regard to regional cooperation, and corresponding Commission action. More specifically, the Regulation applies to the five dimensions of the Energy Union, which are closely related and mutually reinforcing: (a) energy security; (b) internal energy market; (c) energy efficiency; (d) decarbonization; and (e) research, innovation and competitiveness.
Therefore, each Member State shall set out in its integrated national energy and climate plan covering the following main objectives, targets and contributions: decarbonization (greenhouse gas emissions and removals, renewable energy); energy efficiency; energy security; internal energy market ; research, innovation and competitiveness.
