Synthesizing the latest findings from the IPCC in partnership with cities and businesses across the globe

Building the Scientific Evidence Base to Accelerate Local Climate Action

The Intergovernmental Panel on Climate Change (IPCC) brings out periodic reports based on the latest and most comprehensive scientific assessment of climate science. 

The Summary for Urban Policymakers initiative develops a companion series to the official IPCC reports, distilling the latest climate change science for the urban context. 

The initial volume in the SUP series was released in November 2018 at COP23, and distilled the findings from the IPCC Special Report on 1.5°C.

The current focus for the SUP initiative is the IPCC AR6 Reports, and will deliver companion reports to the IPCC’s series of three Working Group Reports and one Synthesis Report.  

SUP reports are authored by the world’s leading climate scientists – a selection of the same individuals who have produced the IPCC reports – who have volunteered to support this effort in their individual capacities, working in consultation with city, local and regional governments; city networks and businesses in every global region.

The AR6 SUP series will draw upon regional and global convenings of scientists, city officials, and business representatives, to provide a bridge between science, policy and practice. These convenings will help translate relevant and recent climate science to foster urban action, and together they will:

  • Review the findings of AR6 reports, from 2018 to 2022.
  • Identify findings, options and delivery pathways of greatest resonance for urban action.
  • Explore avenues for collaborative action to strengthen implementation of sustainable development, climate adaptation and mitigation.

Further SUP derivative products may target specific regions, business sectors, and key issues crucial to address climate change, in support of immediate and longer-term local action.
