Turning the tide on climate change with green sand beaches
Project Vesta was created after a sweeping review of existing and proposed carbon dioxide removal technologies and techniques. While evaluating the potential for the various methods, the enhanced coastal olivine weathering stood out as having the greatest potential for global scale carbon dioxide removal. It makes sense, as it is a nature-based solution, which the Earth has used on geological time scales to balance CO2 emissions. The process is known as the “global thermostat” and the weathering of silicates and carbonate rocks itself is the process by which 99.9% of carbon on Earth has become stored in rock and sediment.
