"Within the region, PM2.5 – fine particulate matter that is a key component of air pollution – come directly from sources like fossil fuel combustion and vehicle exhaust, or is formed from chemical reactions between gases in the air.

In 2019, 64 per cent of total PM2.5 pollution in the region originated from sources like burning of biomass like wood, residential activities and fossil fuel combustion, said Professor Steve Yim, who led the study."

"Cycle lanes, electric cars and other interventions have helped 19 global cities slash levels of pollutants by more than 20%.
The report found “substantial reductions” can be achieved within 15 years through deliberate action.
Beijing and Warsaw topped the ranking for cleaning up fine particulate pollution (PM2.5), reducing levels by more than 45%, while Amsterdam and Rotterdam saw the greatest improvement in nitrogen dioxide (NO2), with cuts of more than 40%."
