Floods, droughts, heatwaves and wildfires already drain tens of billions of euros from the European economy every year.
A new press conference from the European Environment Agency (EEA) makes a clear case that accelerating investment in climate adaptation across agriculture, energy and transport is no longer an option, but is essential to safeguard Europe’s prosperity and competitiveness.
What climate adaptation actually means
Climate adaptation refers to adjusting systems, infrastructure, and practices to reduce vulnerability to the impacts of climate change and cope with its inevitable consequences.
Unlike mitigation, which focuses on reducing greenhouse gas emissions, climate adaptation accepts that some degree of climate change is already present and aims to limit its damage.
Adaptation in agriculture includes moving to more drought-tolerant crops, improving soil health to retain water, and modernizing irrigation systems to use water more efficiently.
In the energy sector, these include strengthening the power grid against heat and storms, diversifying renewable energy sources, and protecting coastal energy infrastructure from rising sea levels.
In the case of transport, climate adaptation may mean redesigning roads and railways to withstand higher temperatures, strengthening infrastructure in flood-prone areas, and strengthening ports against storm surges.
These measures are not just defensive measures. When designed properly, systems can modernize, improve efficiency, and support long-term economic resilience.
It is becoming the norm that extreme weather events incur high costs.
Between 2021 and 2024 alone, extreme weather events are costing Europe an estimated €40-50 billion a year. Over the long period from 1980 to 2024, direct economic losses amounted to approximately 822 billion euros, the highest annual losses in recent years.
These numbers only capture direct losses, such as destroyed infrastructure, damaged crops, and disrupted transportation networks. Wider economic impacts, such as supply chain disruptions and long-term productivity losses, will further increase real costs.
The EEA’s explanation emphasizes that agriculture, energy and transport are at the forefront of climate impacts.
Crops are increasingly exposed to drought and heat stress, and power systems face higher cooling demands and risks to power generation and the grid.
At the same time, transportation infrastructure is vulnerable to flooding, heat damage, and coastal erosion. As extreme weather events intensify, so do the financial risks for these critical sectors.
Investment gap in climate adaptation
According to the EEA, spending will need to increase significantly to make these sectors climate resilient.
By 2050, investments of between €53 billion and €137 billion per year will be required, depending on whether global warming remains at 1.5-2°C or rises to 3°C above pre-industrial levels. By 2100, these annual figures could rise from €59 billion to €173 billion.
However, it is estimated that currently only €15-16 billion a year is being spent on climate change adaptation in agriculture, energy and transport. Most of this comes from public funds at EU, national and regional levels, highlighting the challenge of mobilizing sufficient private capital.
Without closing this gap, Europe risks increasing future losses that far exceed the costs of acting now.
Why climate change adaptation is economically beneficial
One of the strongest arguments for climate adaptation is return on investment. Research by the European Commission’s Joint Research Center shows that adapting to the growing risk of coastal flooding in the EU can yield benefits of around €6 for every €1 spent.
The World Resources Institute found that at a global level, every dollar invested in adaptation generates a return of more than $10.50 over 10 years, with an average project return of 27%.
The EEA also points to a broader economic framework that helps explain these benefits. Adaptation often delivers a “double dividend” by mitigating climate risks while supporting sustainability and emissions reductions.
Nature-based solutions such as wetland restoration are a prime example, as they protect against flooding while storing carbon. In some cases, adaptation not only avoids losses, but also stimulates economic growth and provides a “triple dividend” with social and environmental co-benefits.
Competitiveness test for Europe
The message from the EEA is clear. Delaying climate adaptation will cost Europe far more than acting decisively now.
Investing in climate-resilient agriculture, energy and transport will not only reduce rising losses from extreme weather events, but also strengthen food security, protect energy systems and improve the reliability of transport networks.
As climate risks increase, Europe’s adaptive capacity will increasingly determine its economic performance. Once considered a secondary policy objective, climate adaptation is rapidly becoming the basis of Europe’s future competitiveness.
