Climatetech directory
Early-Stage Climatetech Startups in Europe
Climatetech covers the technologies that cut greenhouse gas emissions and help societies adapt to a warming planet, spanning clean energy, carbon removal, heavy industry, and resilient infrastructure. Europe is a strong base for the sector thanks to ambitious decarbonization policy, deep engineering talent, and a dense network of research institutions and industrial partners. The result is a wave of companies turning climate science into commercial products at scale.

Why climatetech now
Regulation across the region is pushing industries and households off fossil fuels on firm timelines, creating durable demand for cleaner alternatives. At the same time the physical effects of climate change, from wildfires to flooding, are driving urgent investment in detection and resilience. That combination of policy pull and real world need makes climatetech one of the most active areas in European technology today.
How we choose these companies
A public directory of early-stage European climatetech startups. We aim to list every company that fits, not a hand-picked few. Here is exactly what that means, and why:
- European: headquartered in Europe (EU, EEA, UK, Switzerland and nearby). We go by where a company is based, not just where it sells, because this is a map of the European ecosystem.
- Early-stage: founded in the last 5 years. That is where the new ideas and the most active part of the ecosystem are; established household-name scaleups are a different list.
- A real product company: builds a scalable technology product or platform. We leave out agencies, consultancies and local service businesses, which do not follow the same path.
- Independent: a standalone company, not a subsidiary or brand of a larger corporation.
- Active: currently operating, with a live website. We re-check regularly and remove companies that shut down, get acquired, or move out of scope.
We list only public information about what each company does. We deliberately do not track or show fundraising: who is raising, who is investing, or how much. This is a directory of companies, not a deal database.
