The Institut de la Finance Durable has published its report ‘France at +4°C: Financing the Economy’s Adaptation to Climate Change’

Based on more than 80 interviews and the work of over 150 stakeholders (businesses, manufacturers, financial institutions, experts and public authorities) who have been working together within the IFD for the past year, this report provides an overview of the funding mechanisms for climate change adaptation in France and sets out practical recommendations to accelerate their roll-out.

Faced with a scenario of global warming of up to +4°C in France by 2100, adaptation is an economic, financial and social imperative. Every euro invested in adaptation prevents up to €10.50 in damage. Adaptation also represents a market opportunity (estimated at $80 billion in turnover in France by 2024), a matter of industrial sovereignty and the resilience of the entire national economy. Investment needs are estimated at €10.6 billion per year until 2050 (European Commission, 2026), with €1.7 billion in public funding mobilised in 2025: the conditions for mobilising private funding are therefore a key issue.
