To address rising climate threats like extreme heat, Mumbai First and the Gates Foundation launched the CLAP initiative. In response, Mumbai First, with support from the Gates Foundation, launched the Community-Led Resilience and Adaptation Program (CLAP). Under CLAP, an expert discussion was co-hosted by JSW Centre for Climate Change and Health and Mumbai First at Masina Hospital, Mumbai on 19 November 2025 to initiate work on Mumbai’s first Health-Centric Heat Action Plan. Drawing lessons from Ahmedabad’s Heat Action Plan, Prof. Dileep Mavalankar highlighted strategies for protecting vulnerable communities, strengthening health system preparedness, and implementing effective heat-response measures. These learnings will be used to engage with the Government of Maharashtra to co-create Mumbai’s official Heat-Health Action Plan, marking a step towards a cooler, safer, and more climate-resilient city.
