According to the Commission's own estimate, making Europe heatwave proof would cost €70 billion per year.

Omissions

• The €70 billion/year figure is the Commission's estimate for total climate ADAPTATION investment needs (EU + Member States + private sector) through 2050, covering all climate hazards (heatwaves, floods, droughts, sea-level rise, etc.), not exclusively heatwave-proofing measures.
• The estimate is based on the 'Assessment of EU and Member States' Adaptation Investment Needs' published by the Commission in January 2026; the Commission itself states the figure is an approximation ('about €70 billion').
• The source was published on 23 January 2026, before the session date (8 July 2026), so the MEP could legitimately have known it.
