The environmental controls on efficiency of enhanced rock weathering in soils [PDF]
Scientific Reports, 2023 Enhanced rock weathering (ERW) in soils is a promising carbon removal technology, but the realistically achievable efficiency, controlled primarily by in situ weathering rates of the applied rocks, is highly uncertain.

Larger rock extraction sites could improve the efficiency of enhanced rock weathering in the United Kingdom [PDF]
Communications Earth & EnvironmentLarge-scale removal of carbon dioxide from the atmosphere is required to meet net-zero targets. Enhanced rock weathering, in which crushed silicate minerals are spread on cropland soils, is a promising approach, but the logistics of its supply chain are ...
