The Law Of Enhanced Weathering For Carbon Dioxide Removal: Volume 2 – Legal Issues Associated With Materials Sourcing, Romany M. Webb

Sabin Center for Climate Change Law

Achieving the Paris Agreement’s goal of limiting the increase in global average temperatures well below 2°C, and ideally to 1.5°C, above pre-industrial levels will likely require the removal of carbon dioxide from the atmosphere. This could be achieved in various ways, including by enhancing natural weathering processes in which carbon dioxide reacts with silicate-based rocks, eventually forming carbonate minerals (e.g., limestone). Research suggests that the amount of carbon dioxide sequestered through this natural process can be increased by grinding silicate-rich minerals (e.g., olivine) or rocks (e.g., dunite) to increase their surface area and then spreading the powder over land or …
