  • ECOS newsletter – July 2025

    The European Standardisation Regulation holds strategic importance for ECOS and is now under revision. Watch this space, as the public consultation is expected in the coming weeks. In other news, we have a new European standard for testing the durability of washing machines and we also discuss ‘the big question’ - what kinds of hydrogen now qualify as ‘low-carbon’ in the EU?

  • Defining low-carbon hydrogen: How to do it right

    The European Commission is about to set new rules on how to calculate greenhouse gas emissions from hydrogen production, defining what can be classified as ‘low-carbon’. What methods and definitions are the most accurate, and how can they be integrated into EU law? Find out in our blog.

  • Joint letter on the Low-Carbon Hydrogen Delegated Act

    Alongside five other NGOs, ECOS calls on the European Commission to strengthen the Low-Carbon Hydrogen Delegated Act by revising the proposed methane default value, updating the global warming potential factor for methane, and using the best available independent methane emissions data.

  • From arithmetic to ambition: How to use hydrogen emissions data to reduce its environmental impact

    With hydrogen high on the political agenda, hydrogen producers are under pressure to measure and report on their environmental impacts. How can they do so effectively? And more importantly: how can they use this knowledge to reduce emissions? Calculators have limits — ambition must be added separately for the numbers to have any use.

  • Home gas leaks double when hydrogen added – lab tests

    Plans to fuel European homes with hydrogen suffered a further blow today as the first published lab tests reveal that leaks rise sharply when hydrogen is added to regular household fossil gas.

  • Leaks, pollution, and emissions: New lab tests shatter claims of hydrogen benefits for homes

    Home gas leaks more than doubled, on average, when best-selling models of cooking hobs were supplied with hydrogen blended with fossil gas under normal household conditions, compared to tests using fossil gas only. The same test on household boilers saw leaks rise by an average of 20%. Have we finally reached the end of the road for the hype of hydrogen in our homes? Read on to find out why hydrogen for domestic use is a dead end.

  • Joint letter – Only a robust low-carbon hydrogen definition will reduce emissions and increase security in Europe

    Joint letter, signed by ECOS, to European Commission Executive Vice-President Maroš Šefčovič and Energy Commissioner Kadri Simson. Industry, environmental NGOs and think tanks come together to call on policymakers to adopt a robust definition for low-carbon hydrogen in the upcoming delegated act (DA) pursuant to article 8 of the Hydrogen and Decarbonised Gas Market Directive.

  • Fossil or Fair: Will EU’s Heating Policy Delay or Accelerate Sustainable Energy Justice?

    Phasing out archaic fossil heating systems in favour of cleaner options is a must in Europe’s quest to cut energy consumption and greenhouse gas emissions. But only one year on from REPowerEU, European lawmakers risk backpedalling on their commitments to a fossil-free future in the Energy Performance of Buildings Directive (EPBD) and ecodesign rules for space and water heaters.

  • Report – Burning question: why hydrogen boilers are not the answer

    The research is crystal clear: hydrogen should not be used to heat homes. It is time for us to leave behind the hype of hydrogen and focus on other more realistic – and immediately available – solutions that are both climate- and consumer-friendly. Find out more in our new report!
