Green roofs in Chennai: A climate solution to tackle rising heatwaves in Tamil Nadu

The rising heat in Tamil Nadu and across India is beginning to worsen the environment. In 2025, The Hindu reported that mercury levels peaked at 39.2°C and 39.7°C in Nungambakkam and Meenambakkam, respectively. The series of summer forecasts issued by the India Meteorological Department indicates a surge in heatwaves across the country in April.

Similar conditions are expected to follow in subsequent months, calling for a broader programme of tree planting, lake rejuvenation, park and open space design, and green roofs.
