Carbon Greenroof Valentijnschool

Carbon Green Rooftop at Valentijnschool – A Living Lab for Carbon Removal

In this short video, we take you to the Valentijnschool in Rotterdam, where an innovative pilot project is transforming a traditional school roof into a climate-positive, CO₂-removing green infrastructure.

The Carbon Green Rooftop is the first rooftop in the Netherlands explicitly designed to remove CO₂ from the atmosphere, not just to reduce emissions or enhance biodiversity. It combines vegetation with enhanced weathering using finely milled Wo20 (soil improver). While the plants provide cooling and ecological value, the underlying substrate captures carbon through natural geochemical reactions.

This rooftop is produced and installed in accordance with the Dutch SNK methodology for carbon removal, ensuring traceability, scientific credibility, and eligibility for future crediting. It serves as a living lab for long-term monitoring, soil and porewater analysis, and MRV refinement.

🎥 Location: Valentijnschool, Rotterdam, The Netherlands
📐 Area: 500 m²
🌍 Technology: Enhanced Weathering (Wo20 soil improver, SNK-compliant)

This pilot is part of our broader mission to develop durable and verifiable carbon removal solutions that integrate seamlessly into urban landscapes.
