Feasible emission scenarios to limit temperature rise

A comprehensive re-analysis of GHG emission pathways finds that in scenarios that limit temperature change to below 2°C, emissions peak before 2020 then fall to 41-46 GtC and continue to fall. Global emissions are currently 48 GtC and rising.

The study, co-authored by IIASA’s Keywan Riahi and published in Nature Climate Change 23 Oct., aims to inform the identification of short-term emission targets compatible with the 2°C limit.
