The Guardian | Research shows that diesel vehicles remain the dominant source of traffic-related air pollution, with exhaust design influencing roadside exposure and diesel cars accounting for the majority of nitrogen oxides, black carbon, and fine particles measured in busy urban streets.

Science | Frequent tunnel cleaning, real-time air quality monitoring, and adoption of next-generation air management technologies can reduce dust resuspension and improve air quality control in enclosed transport environments.

Electrek | Beijing achieved its cleanest air on record in 2025, with a dramatic drop in PM2.5 pollution and a record number of clear-air days driven by strict emissions controls, industrial limits, and the rapid adoption of electric vehicles.

Planet Detroit | Detroit experienced its highest air pollution levels of the year as winter weather conditions trapped PM2.5 near the surface, briefly pushing the AQI into the unhealthy range for sensitive groups before improving later in the week as winds increased.

Association of Health Care Journalists | Air pollution is a global public health emergency responsible for about seven million premature deaths each year, harming nearly every organ system and remains dangerously underrecognized in medical training and public awareness.

Yale Climate Connections | Climate Trace uses satellite data to track greenhouse gases and harmful air pollutants from industrial facilities worldwide, highlighting how sources of climate emissions like CO₂ and methane also contribute to deadly air pollutants such as PM2.5, SO₂, and NOx.

ProPublica | The EPA’s authority to tighten air pollution rules based on new science is being questioned amid a legal reconsideration that could limit its ability to regulate hazardous pollutants like ethylene oxide, despite evidence of far greater cancer risks than previously understood.
