Researchers use satellite data to show vehicles are an under-recognized source of urban ammonia pollution

Green Car Congress

Researchers now report in ACS’ Environmental Science & Technology Letters that satellite data from before and during the spring 2020 lockdown in Los Angeles shows that vehicles, rather than agriculture, are the main source of urban airborne ammonia (NH 3 ), which forms small particles that contribute to air pollution and harm human health.

China-based study concludes using political incentives to fight pollution is costly and inefficient

The study looked at water quality regulations and found that local officials more heavily enforced regulations on polluting firms that were monitored and tracked by the central government, while not enforcing regulations on firms not tracked. This caused tracked firms to be significantly less productive and firms not tracked to continue to pollute. The productivity loss was mainly driven by upstream polluters investing more in abatement equipment to meet tighter regulations.
