Research has found that speeding up the naturally occurring process of the weathering of rock to draw CO2 out of the atmosphere could help to significantly stabilise the climate and avert ocean acidification caused by humans burning fossil fuels. This is referred to as ‘enhanced rock weathering’.

The supply chain of the enhanced weathering process will require the mining, comminution, transportation and application of these silicate rocks in targeted areas to result in significant draw-down in CO2. My research looks into ensuring sustainability of the process by measuring the economic, environmental and social impacts.
