Major activities affecting India’s air pollution are transportation, biomass burning, electricity generation, industry, construction, etc. The transportation sector is one of the major causes of India’s pollution. It is the leading PM2.5 emission source across cities.
Giving a contextual global report, Avinash Chanchal (climate campaigner) said, many cities including Delhi have recorded a marginal improvement. In air quality due to lockdown. Though, the health and economic cost of air pollution remain severe. The government should prioritize sustainable and clean energy sources. The cities need to encourage low-cost, choices like walking, cycling, and accessible public transport.
