LEAVE NO STONE UNTURNED: THE IMPORTANCE OF ROCK CHOICE FOR SCALING ENHANCED WEATHERING FOR CARBON DIOXIDE REMOVAL

Maurice Bryson

SUMMARY:

The devastating effects of breaching climatic tipping points and our current greenhouse gas emissions trajectory mean that society
must rapidly decarbonize and durably and safely remove and store carbon dioxide (CO2) at an unprecedented scale. To reduce
atmospheric CO2 concentrations to pre-industrial levels, the carbon dioxide removal (CDR) industry will have to remove
approximately 1,000 billion tonnes of CO2 from the atmosphere.
What options do we have to tackle this seemingly intractable problem and reach climate-relevant scales of CDR? One promising
solution uses rocks and rain to durably remove and store atmospheric CO2 in a process known as enhanced weathering. To
understand this process, it is helpful first to review what happens during the natural weathering process.
