In the next 40 years, the world will witness the construction of double the amount of infrastructure as there is in the world today. Steel and cement are integral to this construction, yet they contribute 15% of global emissions. Cocoon is committed to addressing the climate emergency by decarbonizing these crucial industries, paving the way for a better future for all.

We are a small and formidable team, backed by world-class and global investors in climate, hardware, and industrial decarbonization.
