Is air conditioning compatible or incompatible with the green transition?

► President
I open this on a question put to the Commission by a journalist after the brutal heatwave Europe has just endured: is air conditioning compatible or incompatible with the green transition? The honest answer is that it depends on how we do it, but the College must give a coherent position, not a shrug. The tension is a microcosm of the whole adaptation-mitigation debate. On one side, extreme heat is now a recurring, lethal reality — thousands of excess deaths each summer, a public-health emergency and a climate-adaptation imperative. Cooling is not a luxury; for the elderly, the sick and workers it is increasingly survival. On the other side, air conditioning drives up electricity demand at exactly the peak moments when grids are most stressed, and conventional units use fluorinated gases with very high global-warming potential. Done badly, mass air conditioning is a vicious cycle. I reject the framing of AC versus the Green Deal. The right frame is how the EU makes cooling compatible with the green transition — efficient appliances, clean electricity, low-GWP refrigerants, and passive measures so we need less of it. The instruments already exist: Ecodesign and energy labelling, the F-gas Regulation, the Energy Performance of Buildings Directive, the renewable and efficiency directives, and the Climate Adaptation Strategy.

► EVP · Green Deal
This portfolio leads, with Energy and Environment. Let me give the honest, science-based answer, because this question is being used rhetorically to suggest the Green Deal is anti-comfort or anti-adaptation. It is neither. Air conditioning is compatible with the green transition, conditionally, and the EU already has the instruments for each condition. One, efficiency: a modern A-rated heat-pump air conditioner uses a fraction of the electricity of an old unit, and reversible heat pumps cool in summer and heat in winter, decarbonising heating and providing cooling from one efficient appliance. Two, clean electricity: AC on an increasingly renewable grid is far less carbon-intensive, and cooling demand peaks in summer daytime, which correlates well with solar generation. Three, low-GWP refrigerants: the real climate villain is not the electricity but the refrigerant leaking from badly maintained units, and the revised F-gas Regulation phases down high-GWP HFCs toward natural and low-GWP refrigerants — the single most important lever, already legislated. Four, passive measures first: the cheapest, greenest cooling is the cooling you never need — insulation, shading, urban green space, district cooling, under the Energy Efficiency First principle. My recommendation: say clearly that air conditioning is compatible with the green transition when it is efficient, clean-powered, uses low-GWP refrigerants, and is the last resort after passive cooling. Frame cooling as adaptation, which the Green Deal embraces — adaptation and mitigation are not opposites.

► Commissioner · Energy
Co-lead, with the grid reality front and centre. The honest concern is the peak: a heatwave drives a simultaneous, continent-wide AC demand spike that can stress grids to the point of brownouts — exactly when we are also losing hydro and thermal-plant efficiency to the heat. The answers: demand-response, with utilities managing peak load; storage, with batteries shifting solar into the evening; interconnection, with the EU grid sharing load across time zones and weather fronts; and efficiency, since every A-rated unit is grid relief. The Electricity Market Reform gives us the tools. But I want the record honest: a badly managed AC surge on an under-built grid is a real risk, and grid investment must keep pace. Cooling is compatible if we build the clean, flexible grid to power it.

► Commissioner · Environment
Co-lead, with the refrigerant point as my red line. The F-gas Regulation is the decisive instrument — HFC refrigerants can have global-warming potentials hundreds to thousands of times that of CO2, and leaking units are a major hidden emissions source. The phase-down to natural and low-GWP refrigerants — propane, CO2, ammonia, R-32 — must be enforced, and end-of-life recovery of refrigerant must be mandatory and policed. There is also an urban-heat-island and nature dimension: green roofs, urban trees and blue-green infrastructure cool cities passively and serve biodiversity, so the Nature Restoration Law and cooling adaptation align. My condition: no backsliding on the F-gas phase-down under demand pressure.

► Commissioner · Health
Strong support, from the adaptation and public-health side. Let me anchor the human stakes: the recent heatwave caused thousands of excess deaths, concentrated among the elderly, the chronically ill, infants and outdoor workers. Cooling is a public-health intervention — cooling centres, AC in care homes and hospitals, heat-health action plans. The framing must not be that AC is a guilty pleasure; for vulnerable people it is life-saving. The green answer is efficient, clean cooling delivered equitably, not less cooling. Public health is a supporting competence under Article 168, so I supply the evidence and coordinate with member states on heat-health plans. I align fully with the conditional-compatibility line.

► EVP · Economy
Support, with an affordability and competitiveness note. Two points. First, efficient heat-pump AC has a higher upfront cost — low-income households facing lethal heat cannot all afford A-rated reversible units. Policy must pair efficiency standards with support, via the Social Climate Fund and renovation grants, or we create a cooling divide where the poor get heat-stress and the rich get comfort. Second, the European heat-pump and cooling industry is a competitiveness opportunity — backing efficient European cooling tech is Draghi-compatible industrial policy. Aligned, with the social dimension flagged.

► Commissioner · Internal Market
Support. The Ecodesign framework and the single market for appliances are mine. Efficient, low-GWP air conditioners and reversible heat pumps are a single-market product story — harmonised standards, the energy label, and a European manufacturing opportunity. Avoid a patchwork of national efficiency rules. Back the European cooling-tech industry.

► Commissioner · Regional Development
Support. Southern and urban regions bear the heaviest cooling burden; cohesion and renovation funds should help finance efficient cooling and building retrofits where the heat and the energy poverty are worst. Fair rollout matters — protection from lethal heat must not be a privilege of the wealthy regions.

► President
I read the room. Unanimous. The College agrees air conditioning is compatible with the green transition under conditions, and that the framing of AC versus the Green Deal is false. The tensions: adaptation versus mitigation — Health insists cooling is a life-saving public-health adaptation; Green Deal and Environment insist it must be efficient, clean-powered and low-GWP. These reconcile: adaptation and mitigation are not opposites. The synthesis is efficient, clean, low-GWP cooling delivered equitably. Efficiency versus affordability — Economy and Regional Development: efficient heat-pump AC costs more upfront; without the Social Climate Fund and renovation grants we create a cooling divide. Demand surge versus grid — Energy is honest that a continent-wide AC peak on an under-built grid is a real risk, met by demand-response, storage, interconnection, efficiency and grid investment. F-gas phase-down versus demand pressure — Environment's red line: no backsliding on the refrigerant phase-down, the biggest hidden climate cost. No blocking objection. I record consensus on a clear line: air conditioning is compatible with the green transition when it is efficient, powered by clean electricity, uses low-GWP refrigerants, and follows passive cooling, and when it is rolled out fairly so protection from lethal heat is not a privilege. Adaptation and mitigation go together. No formal vote.
