BEATING THE HEAT

On September 2, 2025, Bhubaneswar became the first Indian city to release an Integrated Heat and Cooling Action Plan (IHCAP) to comprehensively tackle two growing crises—rising heat stress and the explosion in air conditioning demand.

Heat stress is not new to India. Over the past two decades, the country has experienced increasingly frequent and intense heatwaves that have claimed thousands of lives, reduced worker productivity, and strained health systems. But the crisis has changed. Cities are now caught in a vicious cycle of heat and cooling: higher temperatures and humidity drive-up air-conditioning use, which worsens the Urban Heat Island (UHI) effect and greenhouse gas emissions. This, in turn, makes cities even hotter—and more dependent on cooling.

It is precisely this cycle that Bhubaneswar’s IHCAP seeks to break. It is India’s first city-level plan that integrates urban planning, green buildings, sustainable cooling, and heat adaptation measures under one umbrella.

A city on the frontline of heat

Bhubaneswar has long been one of India’s most heat-affected cities. Over the last four decades, average temperatures and humidity levels have risen steadily across the year. Even more worrying is the rise in nighttime temperatures, which robs people of relief and increases health risks. Today, heat stress stretches from February to October. As per the IMD’s “Feels Like” index, which uses temperature and humidity to measure heat stress, the city endured nearly 230 days of Yellow or Orange heat alerts in 2024.
