IAS officer Supriya Sahu has been honored as a 2025 UN Champions of the Earth laureate in the Inspiration and Action category. This award is a top international recognition for outstanding work in environmental protection.
The ceremony took place in Nairobi, organized by the UN Environment Programme (UNEP). This year, the laureates were celebrated for their innovative solutions tackling climate change, biodiversity loss, and pollution. Sahu stood out for her commitment to initiatives like plastic reduction, wildlife conservation, and sustainable cooling in India.
One of her notable projects in Tamil Nadu is the Cool Roof Project. It targets urban heat issues, especially in Chennai. By applying a special cool roof paint on residential buildings, indoor temperatures dropped by 5 to 8 degrees Celsius during summer. This technique, with a Solar Reflective Index of 102, not only makes homes cooler but also lowers energy consumption—an essential factor for vulnerable communities.
UNEP described this project as transformative, highlighting its affordability and efficiency. It’s a clear example of how local initiatives can yield significant benefits in the face of climate challenges.
Sahu’s acceptance speech resonated deeply, emphasizing the need for climate action as a collective movement. She shared personal experiences, like witnessing wildlife struggling with plastic pollution in the Nilgiris. These moments reinforced her belief that protecting nature ultimately protects communities.
Tamil Nadu Chief Minister MK Stalin expressed pride in Sahu’s achievements, noting how the award acknowledges her extensive work in wetland restoration and species protection. He hopes this recognition will further motivate her efforts and strengthen the state’s resolve against climate change.
Moreover, according to recent studies by the World Resources Institute, urban areas are key battlegrounds against rising temperatures. Cities like Chennai, facing heat stress, must adopt innovative solutions like Sahu’s. With more than 50% of the global population living in urban areas, impactful local projects can lead to broader climate resilience.
As communities worldwide confront environmental challenges, the stories of leaders like Supriya Sahu inspire action and hope. More voices advocating for the planet can lead to real, lasting changes.
