“Negative emissions no longer a choice, but a necessity” - study
Potsdam Institute for Climate Impact Research (PIK)
If the Paris Agreement’s targets are to be met, future CO₂ emissions must be kept within a finite budget, and the more this budget is overrun, the more relevant carbon dioxide removal technologies will become – and those come with great uncertainties,” writes the Potsdam Institute for Climate Impact Research (PIK) in a press release. “Negative emissions are no longer a choice but rather a necessity,” said PIK’s Gunnar Luderer, author of a study on residual fossil CO₂ emissions in 1.5-2°Celsius pathways. Around 640–950 gigatonnes of CO₂ removal is required for a chance to limit end-of-century warming to 1.5°C, write the authors.
