NEWS

  • Bengaluru, Ahmedabad, and Mumbai have joined a global coalition of 33 cities to tackle rising urban temperatures.
  • The initiative, named the Cool Cities Accelerator, was announced at the C40 World Mayors Summit in Rio de Janeiro.
  • These cities will redesign urban spaces and protect citizens from the impacts of extreme heat.

HIGHLIGHTS

About the Cool Cities Accelerator

  • The programme brings together 33 founding cities representing 145 million people worldwide.
  • Global members include Austin, Boston, Buenos Aires, Freetown, London, Nairobi, Phoenix, Paris, and Singapore.
  • The goal: to safeguard residents and transform cities for a hotter climate by 2030.

Supporting Organisations

  • Major support comes from:
    • The Rockefeller Foundation
    • ClimateWorks Foundation
    • Robert Wood Johnson Foundation
    • Z Zurich Foundation
    • Danish Ministry of Foreign Affairs

 Why It Matters

  • Extreme heat is now the deadliest weather-related hazard, causing nearly 500,000 deaths annually.
  • Without action, urban heat exposure could increase fivefold by 2050.
  • Most deaths are preventable through better cooling access, health interventions, and resilient infrastructure.

Key Actions and Targets

  • Short-term (2 years):
    • Establish heat leadership in cities.
    • Strengthen early warning systems.
    • Ensure emergency cooling access for vulnerable populations.
  • Long-term (5 years):
    • Redesign cities through improved building standards.
    • Expand urban tree cover and shaded spaces.
    • Future-proof critical infrastructure against rising temperatures.

Financial Support

  • The Rockefeller Foundation has committed $1 million to:
    • Develop heat adaptation targets.
    • Provide technical assistance for implementing cooling solutions.
