2 Billion Tonnes of CO2 Could be Absorbed From the Atmosphere Each Year by Applying Rock Dust to Farmland

Adding crushed rock dust to farmland could draw down up to two billion tonnes of carbon dioxide (CO2) from the air per year and help meet key global climate targets, according to a major new study led by the University of Sheffield.

  • Major new study shows adding rock dust to farmland could remove carbon dioxide (CO2) equivalent to more than the current total emissions from global aviation and shipping combined — or around half of Europe’s current total emissions
  • Research identifies the nation-by-nation potential for CO2 drawdown, as well as the costs and the engineering challenges involved
  • Findings reveal the world’s highest emitters (China, India and the US) also have the greatest potential to remove CO2 from…
