The SUP initiative has developed a companion series to the official IPCC reports, distilling the latest climate change science for the urban context.

Following the launch of the first three SUP reports (Volumes I-III), the SUP initiative has also released a stand-alone Action Agenda, which captures the key findings from the SUP volumes, but goes beyond the SUP series and the foundational IPCC reports, to include inputs from city and business leaders gathered through a series of regional convenings. Distinct from the official SUP series, which is authored by the scientific community with input from practitioners, the Action Agenda is written from the perspective of city and business leaders and organizations that represent them. It is informed by and grounded in the knowledge derived from the findings of the SUP process, and with the goal of establishing a long-term platform to co-create and scale urban solutions based in science. 

The Action Agenda is now available for download, following its launch at COP 27 in Sharm-El-Shaikh, Egypt on 16 November 2022.
