Climate-proofing the agriculture, energy and transport sectors would help avoid billions of euros in losses from the accelerating extreme weather events related to climate change. At the same time, it would increase Europe’s competitiveness, according to a briefing published today by the European Environment Agency (EEA).
The three economic sectors are highly vulnerable to climate change, shows the EEA briefing “Making agriculture, energy and transport climate resilient: how much money is required and what will it deliver?”.
As Europe is the fastest-warming continent, the effects of climate change are already here with accelerating extreme weather events such as floods, droughts, heatwaves and wildfires costing Europe EUR 40-50 billion per year.
Investment gap of more than EUR 100 billion per year
The investments required range between EUR 53bn and 137bn annually by 2050 and a further EUR 59-173bn annually by 2100 depending on whether the temperature will rise by 1.5°C to 2°C, or by 3°C compared to pre-industrial temperatures. Current committed funding levels are estimated at just EUR 15-16bn per year for these sectors. The funding comes mostly from the public sector, at EU, national and regional level.
To put things into perspective, the EU experienced annual economic losses of around EUR 40-50 bn per year between 2021 and 2024 due to extreme weather events, totalling EUR 822 bn over the period 1980–2024. The costs are increasing, the years between 2021 and 2024 accounting for the biggest annual losses. As those figures account for direct losses only, the sum of total costs will be higher.
Return on investment for climate-proofing
Investing in climate adaptation delivers benefits beyond just avoiding losses from extreme events: adapting to rising coastal flood risks in the EU would deliver EUR 6 for every euro invested, according to a study by the Joint Research Centre of the European Commission.
Another study, on a global level, by the World Resources Institute, concluded that every US dollar invested in adaptation may bring over USD 10.50 in benefits over a 10-year period and yield average returns of 27% per project.
Double and triple dividend of adaptation investments
When discussing benefits of climate adaptation, two concepts are relevant:
- The double dividend concept: reducing climate risks not only protects people, infrastructure and economies from the damages created by climate impacts (adaptation dividend) but also helps cutting greenhouse gas emissions or boosts sustainability (mitigation dividend). For example, in the case of nature-based solutions, restoring wetlands both protects against floods and stores CO2.
- The triple dividend concept: not only avoiding losses but also unlocking economic potential and generating development co-benefits, as illustrated in Figure 1 and 2.

The case is clear: investing now in making agriculture, energy and transport climate resilient would contribute to Europe’s competitiveness and would help with other challenges, such as food security.
This briefing is part of an ongoing series of EEA products that explore the costs and benefits of climate adaptation. Together, these products provide insight into the economics of climate resilience.
