The Summary for Urban Policymakers (SUP)
August 2021
report series will distill the findings of the IPCC
6th Assessment Report for an urban context.
This unprecedented effort brings together the
IPCC scientists with cities and city networks, the
business community and other key stakeholders
to ensure the most up-to-date science is translated
in the most meaningful way to support immediate
and informed action at the local level.

Summary for Urban Policymakers
6th Assessment Report of the IPCC
Opportunities for engagement include:
• Review and respond to the reports while they are being drafted.
The reports will be authored exclusively by the IPCC scientists and
coordinating lead authors, but business leaders will have the
opportunity to review and highlight key points.
• Endorse the AR6 SUP reports, alongside other business leaders,
urban and national policymakers and other key stakeholders.
• Participate in deeper consultation, regional dialogues and/or
workshops with other private sector leaders, cities and NGOs to
represent the business perspective, connect the private and public
sectors, and inform the SUPM effort.
• Participate in potential spin-off documents and statements that
draw on the AR6 SUP material but that particularly targets business
sectors, regions, or discrete issues of priority to private sector leaders.
Findings through
an Urban Lens
Ian Klaus
Series Editor
Chicago Council on Global Affairs;
Co-lead SR1.5 Summary for Urban
Policymakers
Headline: Climate Change has been influenced by Human Activity
"It is unequivocal that human influence has warmed the atmosphere, ocean and
land. Widespread and rapid changes in the atmosphere, ocean, cryosphere and
biosphere have occurred." (SPM, A.1)
• “Observed increases in well-mixed greenhouse gas (GHG) concentrations
since around 1750 are unequivocally caused by human activities. Since 2011
(measurements reported in AR5), concentrations have continued to increase in
the atmosphere, reaching annual averages of 410 ppm for carbon dioxide
(CO2)...” (SPM, A.1.1)
• "Each of the last four decades has been successively warmer than any decade
that preceded it since 1850. Global surface temperature in the first two
decades of the 21st century (2001-2020) was 0.99 [0.84- 1.10] °C higher than
1850-1900…” (SPM A.1.2)
Translation: Climate Change is Human-induced, unprecedented and long-term • Cities and urban areas are significant contributors to anthropogenic warming. Many climate changes may already be irreversible for centuries to millennia especially in oceans, ice sheets and sea level. • Urgent & systemic responses are needed in the next decade: Global surface temperature will continue to rise until at least mid- century under all emissions scenarios. Global warming of 1.5°C and 2°C will be exceeded during the 21st century unless deep GHG emissions reductions occur in the coming decades.
Headline: Climate Change Impacts are Everywhere, but are Differentiated by Region • “Climate change is affecting every inhabited region across the globe. There is no place, no person and no ecosystem left unimpacted.” (SPM Figure 3) • “The IPCC AR6 WGI inhabited regions are displayed as hexagons with identical size in their approximate geographical location (see legend for regional acronyms). All assessments are made for each region as a whole and for the 1950s to the present. Assessments made on different time scales or more local spatial scales might differ from what is shown in the figure. The colours in each panel represent the four outcomes of the assessment on observed changes. White and light grey striped hexagons are used where there is low agreement in the type of change for the region as a whole, and grey hexagons are used when there is limited data and/or literature that prevents an assessment of the region as a whole...” (SPM Figure 3)
Translation: There is no place, no person and no ecosystem
left unimpactedHeadline: Urban areas are significant contributors to climate
change.
• “Cities intensify human-induced warming locally, and further urbanization together with more frequent
hot extremes will increase the severity of heatwaves (very high confidence). Urbanization also increases
mean and heavy precipitation over and/or downwind of cities (medium confidence) and resulting runoff
intensity (high confidence).” (SPM.C.2.6)
•
There is medium evidence but high agreement (Parker, 2010; Zhang et al., 2013; Chen et al., 2016b)
that the global annual mean surface air temperature response to urbanization is negligible. There is very
high confidence that the different observed warming trend in cities as compared to their surroundings
can partly be attributed to urbanization (Box 10.3, Figure 1; Park et al., 2017).” (Box 10.3)
•
There is very high confidence (robust evidence and high agreement) that the annual-mean minimum
temperature is more affected by urbanization than the maximum temperature … There is medium
confidence (medium evidence and medium agreement) (Schlünzen et al., 2010; Ganeshan et al., 2013;
Ganeshan and Murtugudde, 2015; Haberlie et al., 2015; Daniels et al., 2016; Liang and Ding, 2017;
McLeod 37 et al., 2017; Li et al., 2020c) that cities induce increases in mean and extreme precipitation
over and downwind of the city especially in the afternoon and early evening.” (Box 10.3)Translation: Urban areas part of the problem…and the solution.
“The battle for Climate change
will be largely won or lost in the
cities” (of the global South)

Seth Schultz
Director
Resilience FirstPotential Areas for Business Engagement
• Global Dialogues organized with businesses, authors and city officials for each report (total of 2-3
Global Dialogues).
• Proposed: 10 businesses appointed by RF to represent specific urban-relevant sectors
• GCoM to appoint 10 city representatives to bring perspectives from each region
• IIHS to appoint 10-20 authors to bring regional and WG perspectives
• Regional Dialogues organized by GCoM in 6 regions globally with possibility of business
participation.
• Proposed: 2-3 businesses participating in the global dialogues, nominate individuals to
participate in each of 6 regional dialogues and “report back” into the broader global dialogue
• Note: Anticipated 10 cities per region and 2-3 authors per region.
• Anticipated commitment as 6 hours per month.Potential Areas for Business Engagement Resilience First will be appointing businesses to engage in the SUP based on: - Sector coverage - Regional representation - Ability to meet time commitment We invite expressions of interest now and in the coming month.
