Air pollution is one of the leading environmental health risks globally, responsible for over 9 million premature deaths each year. In India, where many urban areas regularly exceed safe air quality limits, the need for timely and precise action is critical.
CSTEP’s research empowers policymakers with robust, real-time data using tools like low-cost sensors and satellite monitoring. By building institutional capacity and enabling data-driven strategies, this work helps lay the foundation for a healthier, more equitable, and environmentally secure future.
CSTEP adopts a science-driven, technology-enabled approach to address the challenge of air pollution. We work closely with state and central pollution control boards to identify pollution sources through advanced emissions inventory modelling and source apportionment studies. By leveraging cutting-edge tools—such as low-cost sensor networks, mobile monitoring units, and satellite-based observations—we generate granular, real-time air quality data. Our efforts also focus on strengthening institutional capacity through training and knowledge-sharing, ensuring that agencies can independently assess air quality and implement effective, location-specific interventions. This integrated approach bridges scientific research and policy action to create a lasting impact.
