India has some of the most polluted cities in the world. Rising air pollution is taking a heavy toll on the health and productivity of citizens. With recent studies pegging the death toll due to air pollution at 9 million, we need urgent, effective solutions.
At CSTEP, we are working with state pollution control agencies and the Central Pollution Control Board to scientifically identify the sources of pollution for effective and targeted interventions. With the use of emerging technologies such as low-cost sensors, mobile monitoring, and satellite-based monitoring of air pollution, CSTEP is looking at ways to make data on air pollution comprehensive, robust, and accessible.
The capacity-building measures initiated by CSTEP ensure that state agencies can scientifically assess, interpret, and formulate effective strategies to check rising air pollution.
