Member states will have to collectively ensure a reduction in energy consumption of at least 11.7% at the EU level by 2030 (compared to the projections of the 2020 Reference Scenario). A robust monitoring and enforcement mechanism will accompany this objective to make sure member states deliver on their national contributions to this binding EU target.

The saving targets should be met through local, regional, and national measures, in different sectors - e.g. public administration, buildings, businesses, data centers, etc. MEPs insisted that the scheme should in particular cover the public sector, which will have to reduce its final energy consumption by 1.9% each year. Member states should also ensure that at least 3% of public buildings are renovated each year into nearly-zero energy buildings or zero-emission buildings. The directive also establishes new requirements for efficient district heating systems.

"The energy crisis is not over. There is no guarantee that the next winter will be as mild as the last one. In the next seven years, we have to deliver the needed structural changes. I am very happy that we succeeded in pushing member states towards far more ambitious energy efficiency targets. This is crucial so that we no longer depend on Russian energy in the future, and can meet our climate targets. Today's vote is a great victory; it is not only good for our climate, but bad for Putin", says rapporteur Niels Fuglsang (S&D, DK).

Parliament adopted the legislation by 471 votes to 147, with 17 abstentions. It will now also have to be endorsed by the Council of Ministers before it can enter into force.

On 14 July 2021, the European Commission adopted the 'Fit for 55' package, adapting existing climate and energy legislation to meet the new EU objective of a minimum 55% reduction in greenhouse gas (GHG) emissions by 2030.

The package included the recast of the existing Energy Efficiency Directive (EED), aligning its provisions with the new 55% GHG target.

By advancing this directive, Members of the European Parliament are responding to citizens' proposals from the conclusions of the Conference on the Future of Europe. The Energy efficiency directive addresses proposal 3(3), which aims to reduce dependencies on oil and gas imports through energy efficiency projects and expansion of clean and renewable energy provision.

The directive also aligns with Proposal 3(5) advocating for investments in renewable energy technologies, and Proposal 3(6) promoting the exploration of new eco-friendly energy sources and storage methods, supporting the EU's climate goals. Furthermore, it aligns with proposal 11(1) which promotes greener production processes by companies, supporting them to identify the best solutions.
