Mon Mar 30 07:17:57 UTC 2026: ### Headline: Mumbai to Combat Urban Heat with Solar Reflective Paint Pilot Project

The Story:
The Brihanmumbai Municipal Corporation (BMC) is launching a pilot project to implement ‘Solar Reflective Paint’ on municipal buildings in Mumbai, aiming to mitigate urban heat stress. The project, slated to begin this summer in the G/South ward, involves applying a white, heat-reflective paint to building rooftops to reduce internal temperatures. This initiative follows recommendations from a 2025 BMC report in consultation with C40 Cities and mirrors similar strategies already in place in cities like Ahmedabad and states like Telangana.

Key Points:

  • The BMC is initiating a pilot project using ‘Solar Reflective Paint’ on municipal buildings in G/South ward to combat urban heat stress.
  • The paint contains additives like titanium dioxide to reflect infrared rays and prevent heat absorption.
  • The project aims to reduce internal building temperatures by approximately five percent.
  • The initiative is aligned with the recommendations of a 2025 BMC report prepared in consultation with C40 Cities.
  • The pilot project’s scope is limited initially to gauge its impact, with potential expansion across the city if successful.

Key Takeaways:

  • Mumbai is actively addressing urban heat island effects through innovative solutions like solar reflective paint.
  • The BMC is prioritizing heat resilience, particularly in vulnerable areas like schools and staff quarters.
  • The success of the pilot project will determine the broader implementation of cool roof technologies across Mumbai.
  • The timing of the project coincides with growing concerns about heat stress in Mumbai, highlighting the urgency of the situation.
  • The BMC’s initiative aligns with broader national efforts to mitigate heat risks, as seen in Telangana’s ‘Cool Roof Policy’.
