Harnessing rock weathering for climate and soils
ClimeRock is a French company developing enhanced rock weathering for carbon removal and healthier soils.
Why carbon removal matters
- Rapid and deep emissions reductions are essential to limit global warming. They must remain the priority.
- Reaching net zero also requires carbon dioxide removal to counterbalance residual emissions that are difficult to eliminate. Developing credible solutions today is part of that effort.
- Our mission is to turn the potential of rock weathering into practical solutions for carbon removal and healthier soils.
Our solution - Enhanced rock weathering
- Enhanced rock weathering (ERW) accelerates a natural process: finely ground silicate rocks are applied to soils, where weathering reactions can remove carbon dioxide from the atmosphere.
- ERW offers a pathway to long-term carbon storage, notably as dissolved bicarbonate. It can also help reduce soil acidity and supply nutrients that support crop growth.
- Performance depends on the rock, soil, climate and farming practices. Field trials are essential to quantify carbon removal, assess agronomic effects and identify suitable application conditions.

Our approach
- Our approach starts with farmers’ needs and local conditions. Through field trials, we assess which silicate materials are suitable and how they perform in practice.
- We evaluate locally available silicate rocks and suitable by-products based on their composition, weathering potential, and agronomic suitability.
- Our research and field trials focus on quantifying carbon removal and agronomic effects, while improving monitoring, reporting and verification (MRV). We are also exploring the potential for local ERW hubs that match agricultural needs with suitable nearby rock sources, in France and other regions with favorable conditions.
