Integrated assessment model for the 1.5° scenario

Collaborators: Ashwin Seshadri (Divecha Centre for Climate Change, Indian Institute of Science, Bangalore)

The Paris Agreement aims to keep “global temperature rise this century well below 2$^\circ$ Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5$^\circ$ Celsius”. We use a stylized integrated assessment model to analyse the feasibility of the 1.5$^\circ$ target. Most integrated assessment and global circulation models that achieve the 1.5$^\circ$ targets use direct air capture, carbon sequestration and other negative emissions technologies. We model the role of these negative emissions technologies. The 1.5$^\circ$ target might be difficult for probable or infeasible depending on the availability and quantum of these technologies.
