respecting the Paris agreement (and limiting global warming to 2°C, or even 1.5°C), requires the use of other ‘tools’ to get rid of difficult residual emissions. to be eliminated. Among these many levers, CDR consists of capturing the carbon dioxide already emitted into the atmosphere. The process ranges from simply planting trees, which naturally absorb carbon to grow, to much more expensive and energy-intensive technologies to directly suck CO2 from the air.
