Countries urged to start bargaining over negative emissions

Countries need to start negotiating who will take responsibility for removing carbon dioxide from the atmosphere, two scientists argued in Nature Climate Change on Monday.

To hold global warming “well below 2C”, as agreed by world leaders in Paris, models assume “negative emissions” will be deployed on a massive scale.

Yet there has been little discussion of how to ramp up the necessary technologies, or who should lead that effort, observed Glen Peters and Oliver Geden.

“Negotiators know that there is a need for negative emissions, but I have never seen anyone take it further,” said Peters, a researcher at Oslo-based research institute Cicero. “It all remains very abstract.”
