Betting on Negative Emissions


Abstract

Bioenergy with carbon capture and storage could be used to remove carbon dioxide from the atmosphere. However, its credibility as a climate change mitigation option is unproven and its widespread deployment in climate stabilization scenarios might become a dangerous distraction.

Sharing a quota on cumulative carbon emissions

Any limit on future global warming is associated with a quota on cumulative global CO2 emissions. We translate this global carbon quota to regional and national scales, on a spectrum of sharing principles that extends from continuation of the present distribution of emissions to an equal per-capita distribution of cumulative emissions.Learn more »

Persistent growth of carbon emissions

Two thirds of the CO2 emission quota consistent with a 2°C temperature limit has already been used, and the total quota will likely be exhausted in a further 30 years at the 2014 emissions rates.Learn more »

Staying below 2°C

Global emissions are tracking the most pessimistic scenarios used by the IPCC. Glen Peters and colleagues present a comparison of emissions with all four sets of scenarios used by the IPCC since 1990, and argue that inertia in both human systems and the climate system make a 2°C goal harder with every day of inaction.Learn more »
