Cities Unite to Combat Extreme Heat

Key Highlights on Cool Cities Accelerator Initiative

Climate Change and Urban Heat

• Indian cities facing record-breaking temperatures are joining a global coalition to tackle extreme heat, seen as a severe impact of climate change.
• The initiative, Cool Cities Accelerator, was announced during the C40 World Mayors Summit in Rio de Janeiro, Brazil.

Coalition Details

• Participants: 33 founding cities, including Bengaluru, Ahmedabad, and Mumbai, along with international cities like Austin, Boston, Buenos Aires, London, and Singapore.
• Population Coverage: The coalition represents over 145 million people globally.

Goals and Framework

• The initiative aims to protect urban residents and redesign cities to cope with higher temperatures by the year 2030.
• Implementing a science-based framework for immediate and long-term actions.

Expected Actions

1. Immediate Actions (2 years):

   • Establish clear heat leadership.
   • Strengthen early warning systems for extreme heat.
   • Ensure access to cooling and hydration during heat emergencies.

2. Long-term Actions (5 years):

   • Improvement of building standards to enhance thermal efficiency.
   • Expansion of urban tree cover and shade.
   • Future-proofing critical infrastructure against rising heat levels.

Funding and Support

• The Rockefeller Foundation has extended a grant of approximately $1 million to the project.
• The funding will facilitate the development of targets for heat adaptation and provide technical assistance to help cities implement solutions.

Public Health Implications

• Extreme heat is responsible for nearly 500,000 deaths per year, making it the deadliest weather-related hazard globally.
• Projections indicate that the number of people vulnerable to life-threatening heat could increase five-fold by 2050 if no action is taken.
• Most heat-related deaths are preventable through timely access to cooling and public health interventions.

Implementation Partners

• Support from various foundations including ClimateWorks Foundation, Robert Wood Johnson Foundation, Z Zurich Foundation, and Danish Ministry of Foreign Affairs.

Conclusion

• The Cool Cities Accelerator signifies a concerted global effort to adapt urban infrastructure and public health measures in response to worsening climate impacts, primarily extreme heat, with a focus on vulnerable populations.
