The energy policy of the European Union focuses on energy security, sustainability, and integrating the energy markets of member states. An increasingly important part of it is climate policy. A key energy policy adopted in 2009 is the 20/20/20 objectives, binding for all EU Member States. The target involved increasing the share of renewable energy in its final energy use to 20%, reduce greenhouse gases by 20% and increase energy efficiency by 20%. After this target was met, new targets for 2030 were set at a 55% reduction of greenhouse gas emissions by 2030 as part of the European Green Deal. After the Russian invasion of Ukraine, the EU's energy policy turned more towards energy security in their REPowerEU policy package, which boosts both renewable deployment and fossil fuel infrastructure for alternative suppliers.

The European Green Deal, approved in 2020, is a set of policy initiatives by the European Commission with the overarching aim of making the European Union (EU) climate neutral in 2050. The plan is to review each existing law on its climate merits, and also introduce new legislation on the circular economy, building renovation, biodiversity, farming and innovation.
