The debilitating smog that sets in every year at this season in northern India this time includes a whiff of irony after India helped lead the charge on watering down the COP26's final statement on phasing out coal. From cars and heavy industry to crop stubble burning by farmers, François Picard's panel looks at the root causes of air pollution in and around New Delhi. How can air quality be drastically improved, fast?
