Analyses by the University of Innsbruck show that traffic restrictions during the first lockdown last March led to a sharp drop in air pollutant emissions, significantly more than for carbon dioxide. The study confirms...
Based on the long-term Potsdam radiation time series, ETH researchers have shown that variations in the intensity of sunlight over decades are down to ultra-fine, man-made dirt particles in the atmosphere. In the late...
Climate change mitigation is about more than just CO2. So-called “short-lived climate-forcing pollutants” such as soot, methane, and tropospheric ozone all have harmful effects. It is common practice in climate policy to bundle the...
The proposed design could reduce nitrogen oxide emissions by 95 percent and thereby reduce the number of associated early deaths by 92 percent, a new MIT study finds. Nitrogen oxides, or NOx, are a...
Researchers identify a mechanism by which small particles in the atmosphere can generate more frequent thunderstorms. Observations of Earth’s atmosphere show that thunderstorms are often stronger in the presence of high concentrations of aerosols...
Particulate emissions from cooking stay in the atmosphere for longer than previously thought, making a prolonged contribution to poor air quality and human health, according to a new study from the University of Birmingham....
Particles that form in the valleys of the Himalayas and are injected into the upper atmosphere could help scientists better predict the future climate because there is little evidence of pollutants in their formation....
High concentrations of PM2.5s may amplify the coronavirus contamination, says new research. It found that increases in cases followed phases where the levels of fine particles in the air were higher. An interdisciplinary team...
The city of Barcelona has announced a 10-year plan to reduce car traffic and pollution by expanding its successful superblock model to the city center. Barcelona’s superblocks are a model of healthier, safer and...
Maritime transport has a direct impact on air quality in many coastal cities. Now, new research is helping track emissions from individual ships in an effort to better monitor air pollution. Commercial ships and...
Cities in California have the most marked activity across the United States when it comes to cutting emissions. San Diego, Los Angeles and San Francisco have reported the biggest emissions cuts since 2017, according...
Air pollution costs inhabitants of European cities more than 160 billion euros ($190 billion) each year due to long- and short-term health impacts, an analysis has found. The research looked at data from more...
When the air outside is polluted, office workers are more likely to order food delivery than go out for lunch, which in turn increases plastic waste from food packaging, according to a study by...
The authorities in India’s capital have introduced a campaign to cut air pollution in time for winter. Polluted air could make the coronavirus pandemic more virulent. Studies have suggested that high levels of air...
China’s efforts to combat aerosol pollution could be exacerbating warming throughout the northern latitudes, say experts. Their model showed that efforts to combat aerosol pollution between 2006 and 2017 resulted in widespread warming. But...
Routing apps routinely capture detailed information as motorists use the GPS technology to plan and navigate routes. Making use of the crowd-sourced data from such apps could provide a low-cost and highly effective alternative...
Drivers and passengers can inhale significantly lower levels of air pollution by setting their vehicle’s ventilation systems more effectively and taking a cleaner route to their destination, a new study reveals. Road transport emissions...
Researchers at Carnegie Mellon University are trialing a mobile sensing platform in the Chinese cities of Shenzhen and Tianjin that places sensors on taxis. Their goal is to improve smart urban services by encouraging...
A UCLA study has revealed that clean air could endure after the COVID-19 lockdown. Achieving net-zero emissions in California by 2050 can prevent thousands of deaths annually in every community, according to the researchers....
The City of Boston has set the goal of becoming carbon neutral by 2050, mainly by cutting emissions. But if the city cut emissions now, over 200 deaths could be avoided and 2.4 billion US dollars...
