70 French Climate Tech Startups To Know

From climate tracking, food and agriculture, energy, materials, and more

After our deep dive into the Swiss climate tech scene, we decided to look across the border and jump into the Climate startups to know in l’hexagone.

The French climate tech scene has great representation in climate tracking, food and agriculture, energy, materials, and more - largely driven by strong technical universities and the active presence of Entrepreneur First.

If there’s someone you think we’ve missed, please add them to the list here.
