JNU Economics Professor Sangeeta Bansal proposed implementing emission taxes in India to combat air pollution, particularly in the Indo-Gangetic Plains. Speaking at Ahmedabad University, she highlighted the region's "valley effect" due to its topography, which traps pollutants. Bansal suggested differentiated taxes to incentivize firms to reduce emissions, adopt cleaner technologies, and relocate from pollution-vulnerable areas, advocating for policies that make operating in such regions more costly.
