33 businesses, industry associations, NGOs, and think tanks joined forces to urge the European Commission to prioritise available efficient and sustainable solutions to decarbonise Europe’s building stock, and avoid the direct use of hydrogen.
Addressing EU Commission Executive Vice-President Frans Timmermans in an open letter, the co-signatories underline that to achieve a higher 2030 EU climate target, massive emissions reductions in the building sector will be needed (<60% compared to 2015). This requires applying the energy efficiency first principle and boost the integration of renewables, as envisaged by the Renovation Wave strategy.
While it is true that renewable hydrogen can play a role in decarbonising hard-to-abate sectors, its direct use for heating on a large scale is problematic because it comes with many uncertainties linked to the scalability, costs of its production and inefficiencies, the letter says.
To optimise the process of heat decarbonisation in the medium and long-term, the EU should favour energy efficiency options as they can immediately deliver real carbon savings, while accommodating a growing share of renewable sources.
The co-signatories call on the Commission not to overestimate the potential of “zero-emission gas”, which would be mostly imported from abroad. Doing that would constrain EU taxpayers to fund unnecessary infrastructures, such as gas pipelines (or their upgrade), diverting financial resources from immediately applicable and more sustainable heat decarbonisation solutions.
Monica Frassoni, President of the European Alliance to Save Energy (EU-ASE), said:
“To achieve higher emission reductions by 2030, the EU must act fast to decarbonise buildings as one of the most energy consuming and polluting sectors. To make this happen, we need to prioritise energy efficiency and renewables, while using hydrogen to decarbonise harder-to-abate sectors, like chemicals and steel.”
The European Alliance to Save Energy (EU-ASE) aims to ensure that the voice of energy efficiency is heard across the European Union. EU-ASE members have operations across the 27 Member States of the European Union, employ over 340.000 people in Europe and have an aggregated annual turnover of €115 billion.

In a fast-changing political and economic environment, 2025 was a year of continued efforts to strengthen security, stability, and competitiveness for European businesses.
Throughout the year, our work demonstrated that energy efficiency is not only essential to achieving climate goals, but also a key driver of innovation, energy independence and sustainable long-term growth across Europe.
Strong engagement with policymakers, combined with the successful organisation of the 4th European Energy Efficiency Day, highlighted the importance of collaboration and dialogue in advancing shared objectives. Partnerships across sectors and institutions remained central to delivering impact and shaping effective energy policies.
Looking ahead to 2026, we will intensify our efforts to secure the regulatory certainty that can accelerate the energy transition, while providing businesses with the investment confidence they need and strengthening Europe’s competitiveness.
