Coastal, Ocean, and Engineered Sinks

Protect and restore ecosystems. Shift agriculture practices. Remove and store carbon.

Ours is a water world. Though Earth has a land-centric name, oceans cover 71% of its surface and make land livable. Some of the planet’s most critical processes happen where sea and air meet, as oceans absorb and redistribute heat and carbon—both rising due to the glut of emissions in the atmosphere. But the sheer quantity of excess greenhouse gases means natural processes can’t do it all when it comes to carbon sequestration. Select nascent technologies show some promise to supplement terrestrial, coastal, and ocean sinks.
