Toward clean air in developing countries: A comparative analysis of PM2.5 trajectories under emission-reduction policies in China and India

Key Points

• PM2.5 levels are projected to decline significantly in both China and India.
• In China, emission-reduction policies are expected to decrease PM2.5 by nearly 30% by 2030.
• Comparative study employs trajectory analysis on air quality data from both countries.
• Results indicate that implementation of stronger emission policies can lead to better air quality outcomes.
