Spreading rock dust across the UK’s farmland could provide almost half of the amount of carbon dioxide removal the country needs to meet its binding net-zero target for 2050, according to a new analysis. According to The recent report by the Intergovernmental Panel, the need to remove vast amounts of carbon dioxide from the atmosphere is “unavoidable” if the world’s climate goals are to be met. Enhanced rock weathering, a process in which rocks such as basalt are ground up to increase their surface area and accelerate the natural reactions through which they absorb carbon from the air, has already been found to be a potential large-scale option for those removals.
