Reversing Climate Change Doubling Nature


Our mission is to solve climate change by removing 1500 gigatons of CO2 from the air. Climate positive entrepreneurs capture carbon with their businesses, ensure healthy work and regenerate the planet. To really move towards scalable concepts, the valuation of carbon is essential. With Climate Cleanup we ensure that carbon valuation becomes part of the business model of entrepreneurs who comply with the donut economy.
