Science to Action

Resilience Rising is working with a range of actors including mayors, civil society organizations, businesses and world-leading scientists, to bridge the gap between science and action, and to catalyze informed, focused and inclusive action around the world. The Summary for Urban Policymakers initiative is one such output of these collaborative efforts.


The Summary for Urban Policymakers

The opportunity for effective, efficient and rapid action in cities depends on accessible, actionable science at the city scale. The Summary for Urban Policymakers (SUP) initiative responds to this need – bringing together the world’s leading scientists with local government policymakers and businesses to co-generate and advance a scientific evidence base to propel implementation and deepen climate action in cities around the world. The Summary for Urban Policymakers series includes three Reports and a derivative Action Agenda that were launched at COP 27 on 11 November 2022.

The SUP reports are a result of collaborative knowledge co-creation over one year and through a series of regional and global convenings held across the world.

Cities are hotspots of global climate emissions and risk, but they are also hubs for innovation, action and resilience.

  • Cities are home to over half the world’s population, generate two-thirds of its economic output, and emit three-fourths of global greenhouse gas (GHG) emissions.
  • Urban areas in low- and middle-income countries are expanding and driving the world economy and job creation. 
  • Cities are a pivotal opportunity for a rapid transition into a sustainable, low-energy intensity development. 
  • Low-carbon, climate-resilient urbanization can limit unsustainable and inequitable development trajectories.
  • Cities can accelerate and deepen climate action towards climate-resilient development in the next few decades.

The opportunity for effective, efficient and rapid action in cities depends on accessible, actionable science at the city scale. 

About SUP

The Intergovernmental Panel on Climate Change (IPCC) brings out periodic reports based on the latest and most comprehensive scientific assessment of climate change. The initial volume of the Summary for Urban Policymakers (SUP) series was released in November 2018 at COP 23, and distilled the findings from the IPCC Special Report on 1.5°C.

The focus for the SUP initiative is the IPCC AR6 Reports and delivering companion reports to the IPCC’s series of three Working Group Reports. The SUP initiative is a series of three summary reports: 

SUP Volume I: What the Latest Physical Science of Climate Change Means for Cities and Urban Areas,
distilled from the IPCC Working Group I report; 

SUP Volume II: What the Latest Science on Impacts, Adaptation and Vulnerability means for Cities and Urban Areas,
distilled from the IPCC Working Group II report; 

SUP Volume III: What the Latest Science on Climate Change Mitigation Means For Cities and Urban Areas,
distilled from the IPCC Working Group III 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; cities and city networks; and businesses in every global region.

The SUP series draws upon regional and global convenings of scientists, city officials, and business representatives, providing a bridge between science, policy and practice. These convenings helped translate relevant and recent climate science to foster urban action, and together they have:

  • Reviewed the findings of IPCC AR6 Reports, from 2018 to 2022.
  • Identified findings, options and delivery pathways of greatest resonance for urban action.
  • Explored 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.

Core Institutional Partners

The Summary for Urban Policymakers (SUP) series is supported by a partnership of the Global Covenant of Mayors for Climate & Energy’s alliance for city climate leadership, the Resilience First business network, the Indian Institute for Human Settlements, the German Federal Ministry for Economic Affairs and Climate Action in collaboration with the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), and led by Resilience Rising.
