Adaptation to climate change: Single climate adaptation fund of €2bn a year (Barnier fund and Fonds vert)

Direction of change: increase, compared with current law.

The lever. Public resources to cope with the effects of global warming (heatwaves, droughts, fires, floods, coastal submersion): national adaptation plan, risk prevention fund, civil protection. Excludes emissions reduction. Direction rule: ↑ more public resources for adaptation.

« Créer un fonds unique d'adaptation au changement climatique, réunissant le fonds Barnier et le Fonds vert, doté de 2 milliards d'euros par an pour des investissements à impact mesurable. »1

Costing

Announced by the candidate

−€2bn

per year, cost to the public accounts. « doté de 2 milliards d'euros par an » [“endowed with 2 billion euros a year”]; « Deux milliards, c'est une somme importante. Mais rapportée aux 5 milliards d'euros que coûtent chaque année les catastrophes naturelles, c'est de l'argent bien investi » [“Two billion is a large sum. But compared with the 5 billion euros that natural disasters cost every year, it is money well invested”] (Les Ponts-de-Cé speech, 17 September 2026, reported by AFP).

Our calculation

−€0.8bn

per year for the public accounts, new spending. Candidate’s amount, taken as is.

The calculation

  • Additional public resources for climate change adaptation: (0.78 − 0) ÷ 1 = 0.78 times “+€1bn a year of public spending on climate change adaptation”, each a cost of €1bn (1 to 1).

Assumption by the editors. Reading adopted: the single fund of €2bn a year brings together existing appropriations; the new spending is the difference from those of the PLF 2027, in payment appropriations: Barnier fund €238.8m and Fonds vert €981.4m, i.e. 2 − 1.22 = €0.78bn a year (candidate's amount used). Other reading: in commitment authorisations (€300m and €1bn), €0.7bn.

Current law, sources and limits of the cost schedule

Current law. Third national climate change adaptation plan (PNACC-3), announced on 10 March 2025, which adopts a reference warming trajectory of +4 °C by 2100. Fonds de prévention des risques naturels majeurs (major natural hazards prevention fund, « fonds Barnier », programme 181): €300m in commitment authorisations and €228.8m in payment appropriations in the LFI 2026; €300m and €238.8m in the PLF 2027. Fonds vert (green fund): €1bn in commitment authorisations and €981.4m in payment appropriations in the PLF 2027, including a dedicated adaptation envelope of €500m in commitment authorisations.

Horizon. Spending in a full year, static: €1 announced = €1 of deficit, compared with current policies.

Limits. Envelope parameter, like public investment or rail: it applies only to an amount announced on top of current resources. A fund announced as a total amount that brings together existing appropriations is counted by the gap with those appropriations, in payment appropriations of the PLF 2027 (Barnier fund €238.8m, Fonds vert €981.4m), the reading in commitment appropriations (€300m and €1bn) being cited in the note. Adaptation spending is scattered (Barnier fund, Fonds vert, civil protection, agriculture, health, local authorities) and has no official total: the Cour des comptes (2024) notes « l'absence de chiffrages exhaustifs et cohérents pour l'ensemble des acteurs publics » [“the absence of exhaustive and consistent costings for all public actors”], and I4CE (2025) identifies €1.7bn explicitly dedicated to adaptation in 2025. Benchmarks, not counted: the National Assembly's flash fact-finding mission on summer 2026 (rapporteur Éric Coquerel) estimates the cost of that summer at about €16bn and puts the public spending needed from summer 2027 at between €10bn and €13.6bn; these are estimates, not coefficients. A plan that funds investment works may overlap a public investment envelope (overlap declared); a plan that strengthens hospitals or care homes (EHPAD) is not also counted on the hospital or old-age levers.

How to read these amounts. These are static costs and revenues, with no feedback effect, over a full year: nothing on growth, employment or the revenue that economic activity would gain or lose. A higher net cost does not on its own make a worse policy, nor net savings a better one: each programme rests on an economic model (demand-led stimulus, lower compulsory levies, consolidation of the public accounts…) that the cost schedule does not settle. GDP itself measures a volume of activity, not well-being or the usefulness of what is produced. Economic models and feedback effects.
