A large part of the worst pollution days in dehi is not from burning fossil fuels but from burning agricultural fields because farmers don't have a more effective way of preparing the fields for the next year. This means that in November the air is the worst, and it slowly starts getting better in December. Even if you just address this problem it will make a huge difference in the air quality.
