Supriya Sahu IAS Current Posting

On 15 July 2026, the Tamil Nadu government reshuffled 17 IAS officers. Sahu moved out of the Environment department. She was appointed Additional Chief Secretary and Commissioner of the Entrepreneurship Development and Innovation Institute, known as EDII-TN.
EDII-TN is based in Guindy, Chennai. It trains and supports new business owners, including small enterprises that want to sell online.
ThePrint reported that the move was not widely expected, and that some activists were upset. A government officer told the outlet that transfers are a routine part of administration.

Supriya Sahu Cool Roof Technology and Key Initiatives

The cool roof idea is simple. A roof painted with white, reflective coating bounces sunlight away instead of soaking it up. The rooms below stay cooler without extra electricity.
Tamil Nadu applied this idea to public schools. UNEP reports that the project covers 200 public “green schools.”
Why does this matter? Chennai residents joke that the weather has three modes: “hot, hotter and hottest.” Sahu says temperatures in government classrooms without air conditioning can rise above 40°C in summer. That makes studying hard and hurts health.
White roofs alone bring the classroom temperature down sharply. UNEP says that when they are combined with shading, natural ventilation and plants, indoor temperatures can fall by 5 to 8°C.
The green schools also use solar power, energy-efficient fans, shade, rainwater harvesting and vegetable gardens. UNEP says Sahu holds this school project especially close to her heart.
The same low-cost ideas are now being extended to social housing. UNEP says families who cannot afford air conditioning could gain about 40 per cent more usable time at home. Those who later buy an air conditioner could cut cooling bills by up to 50 per cent. The measures are also expected to enter the state’s building rules.
| Initiative | What It Does | Reported Result |
|---|---|---|
| Cool Roof Project | Reflective white roofs on school buildings | Implemented in 200 public green schools |
| Tamil Nadu Green Climate Company | State climate vehicle that runs four missions: Green Tamil Nadu, Climate Change, Wetlands and Coastal Restoration | India’s first not-for-profit state climate vehicle |
| Meendum Manjappai (2022) | Brings back the yellow cloth bag to fight single-use plastic | Launched by Chief Minister M K Stalin |
| Heat as a state disaster | Tamil Nadu formally declared heat a state-specific disaster | First state in India to do so, per UNEP |
| Forest and wetland recovery | Tree planting, new reserve forests, mangrove and wetland protection | Over 100 million trees, 65 new reserve forests, mangrove cover doubled, wetland sites up from one to twenty (UN India) |
