Renforth (2023): Remediating the sky: the role of geoenvironmental engineers and applied geoscientists in geochemical carbon dioxide removal

P. Renforth IN: Quarterly Journal of Engineering Geology and Hydrogeology, https://doi.org/10.1144/qjegh2023-053

This briefing introduces the field of geochemical CO₂ removal (gCDR), which proposes to accelerate the natural reaction of atmospheric CO₂ with rocks or anthropogenic materials. It also explores the critical role geoenvironmental engineers and geoscientists will have in researching and deploying these technologies. While currently at an early stage of development, it is possible that gCDR will operate at a global scale (billion tonnes of CO₂ per year) by mid/late-century, resulting in an industry that generates $100s billions to $1 trillion in annual revenue, equivalent in scale to the present day oil industry.
