Ep.23: Doubling nature to restore the climate with Sven Jense and Eelco Leemans
Sven Jense is the founder of Climate Cleanup an entrepreneurial non-profit organization with the mission of restoring the global carbon balance by removing 1500 gigaton of CO2 out of the atmosphere using natural climate solutions (NCS). One of the most promising and scalable solutions is seaweed. Eelco Leemans joined Climate Cleanup to work on marine solutions and how the oceans can help to sequester carbon. Together they are investigating if Sargassum can help.
