The refinq 100

Europe’s 100 most

climate-exposed regions.

Scoring regions for climate exposure is what we do every day. So when the European Commission announced it will name 100 vulnerable territories this October, we ran the same question across every region in the EU, all 1,165 of them.

Findings

What the data says

01

Three countries hold three quarters of the list.

Italy 40, Spain 22, Greece 12. The other 26 regions are spread across six member states.

02

Heat leads in 51 of the 100.

Water scarcity in 39. Wildfire in 8, flood in 2. And no region on the list has just one problem. Every single one scores high on at least two hazards at the same time.

03

Austria enters the ranking at 294 of 1,165.

That is the Weinviertel, north of Vienna. By 2080 its heat climbs two steps on the five-step scale and its water scarcity climbs one, to the second-highest.

Plain average · 0 to 100

And then it gets interesting

This map is the shallowest thing we do

One number per region is the wide-angle view. It is enough to see where Europe’s exposure concentrates and how countries compare. What sits underneath it runs one address at a time, at a resolution no regional map can show.

01 Region

Every region in the EU, four hazards, one number each.

02 Asset

We score every site against more than 20 physical climate hazards, out to 2100. The hazard list is the one the EU Taxonomy and the ESRS guidelines set out; the projections come from the climate models the IPCC works with.

03 Nature and transition

What that site takes from nature, what it costs nature, and how policy, markets, technology and public opinion are shifting around it.

04 Action

Knowing the number is only half of it. We also return what to do about it: adaptation measures on the climate side, mitigation measures on the nature side, and only where a risk actually lands in the High or Very High band.

Method

How the ranking is built

Unit

Europe’s standard statistical regions (NUTS-3), roughly a province or a district. 2024 definition, from Eurostat.

Hazards and data

Heat, water scarcity, wildfire, flood. Sources: Copernicus C3S, WRI Aqueduct 4.0, JRC.

Scenario, horizon

High emissions, no further climate policy (RCP8.5 / SSP5-8.5). Year 2080, compared against 2006 to 2025.

Scale

0 to 100 combined, higher means more exposed.

Aggregation

We score what is actually built in a region, site by site, then add it up to the region.

Combined score

The plain average of the four hazards. None counts for more than another.

Region boundaries come from Eurostat’s GISCO service (NUTS 2024) © EuroGeographics. The satellite imagery on the map is by Esri, Maxar and Earthstar Geographics. All scores are refinq’s own.

Exposure is not vulnerability.

This ranking measures how hard climate hazards hit what is built in a region. It does not measure how well that region is prepared for them. A region can rank high here and still be in good shape, because it has defences, money and a plan. The European Commission is assessing vulnerability, which adds exactly those things in. The two views belong together, and the interesting places are the ones where they disagree.
