Negative Emission and the Carbon Cycle

In collaboration with the Global Carbon Project (GCP), IIASA will host this workshop focusing on what are the biophysical, economical and technological constraints and opportunities to the supply of negative emissions.

In order to meet the 2°C climate target adopted by the global community, anthropogenic GHG emissions need to peak in the next decade or so, and decline rapidly thereafter, reaching 50–70% of 1990 levels by 2050. In many scenarios, in order to meet the target, there is a requirement for net anthropogenic emissions to be negative by mid-century.

Negative emissions are achieved when human activities lead to a net removal of CO2 from the atmosphere. A delay in peaking or a reduction in the rate of decline after peak further increases the need for negative emissions, as is also the case when there are more stringent climate targets (e.g., 1.5°C). Even with higher temperature targets, eventually emissions need to become zero, and negative emissions may still be necessary to offset the most likely inevitable emissions from the production of food and bioenergy.
