Carbon Dioxide Removal Primer

The interest in CDR is growing. Why is this? Because it is becoming apparent that we are not going to reduce our CO2 emissions fast enough to avoid surpassing the 2°C goal. As a result, if we exceed the carbon budget associated with 2°C warming, CDR technologies could remove CO2 from the atmosphere to bring the carbon budget back into balance.

Carbon dioxide removal offers a way to change the math. Extract large amounts of CO2 from the atmosphere and “negative emissions” could, conceivably, balance out the positive variety. It might even be feasible to cross the threshold of catastrophe and then suck enough carbon out of the…
