Urban planners should plant hedges—or a combination of trees with hedges—rather than just relying on roadside trees if they are most effectively to reduce pollution exposure from cars in near-road environments, according to a new study from the University of Surrey. The best way to tackle pollution is to control it at the source.
Less traffic on the roads during the first COVID-19 lockdown in the UK led to a reduction in air pollution but may have caused potentially damaging surface ozone levels to rise, according to a new study led by researchers at the University of York. The 25–75% range is shown by the shaded area. —Professor Lee.
in 2030 even if India were to comply with its existing pollution control policies and regulations. In 2015, more than half the Indian population—about 670 million citizens—were exposed to PM 2.5 The program focuses on 102 polluted Indian cities and aims to reduce PM 2.5 levels by 20-30% over the next five years.

The low-emission vehicle (LEV) standard requires vehicle manufacturers to deliver passenger cars, trucks, and SUVs that produce lower greenhouse gas emissions and other pollutants for sale in Minnesota. The policy will implement two clean cars standards to reduce vehicle emissions.
New York City Clean Air Taxi rules are successful in cutting emissions and reducing air pollution, [link] to a new study by researchers at the Columbia University Mailman School of Public Health and Drexel University. They also found these emission reductions were associated with decreases in concentrations of pollutants in the city’s air.
From 2011 to 2015, California experienced its worst drought on record, with a parching combination of high temperatures and low precipitation. Although ozone in the stratosphere protects the earth from ultraviolet radiation, at ground level the molecule is a harmful air pollutant to humans, animals and plants. Geddes, Xi Yang, Emily Y.
A recently released total fuel cycle analysis for maritime case studies shows that natural gas fuels reduce some air quality pollutants substantially, and reduce major greenhouse gas (GHG) emissions slightly, when compared to conventional petroleum-based marine fuels (low-sulfur and high-sulfur). This is an important consideration.
Despite an increase in vehicle miles traveled (VMT) of 13% from 2002 to 2015 (the latest year for which data are available), the total amount of airborne pollutants emitted from highway vehicles has declined considerably, according to the US Department of Energy (DOE).

It’s critical that governments adopt and enforce WHO guidelines for air pollution immediately.
Results of new analysis conducted by German and Swiss researchers suggests that air pollution directly affects cognition and is not mediated by lung function; put another way, the two are independent risk factors for cognitive decline. 2015) “ The Roles of Lung Function and Air Pollution on Cognitive Decline: Predictor and Mediator? ”
A Sandia National Laboratories project team, including a number of industry partners, is designing and building a cold-ironing fuel cell system that will be deployed in the Port of Honolulu in 2015. Ports have been a major source of water and air pollution in the US, but remained relatively unregulated until recent years.
They monitored indoor and outdoor ozone levels, along with other pollutants. In 2015, 108 million Americans—one third of the population—lived in counties with ozone levels that exceeded standards set by the EPA. In contrast, only 31 million Americans live in counties where other pollutants exceed EPA standards.
Air pollution varies widely over the course of a day and by location, even within the same city. Now scientists, reporting in the ACS journal Environmental Science & Technology , have used smartphone and sensing technology better to pinpoint where and when pollution is at its worst. Nieuwenhuijsen et al. Nieuwenhuijsen et al.
We need to understand this multiphase chemistry in the atmosphere to design an efficient strategy to manage air pollution and accurately predict future air pollution and climate change impacts. The oxygen trapped in this ice provided evidence of sulfate composition from 1959 to 2015, without contamination from local pollution.
At an event in Sacramento, California, Volvo Trucks announced that it will commercialize dimethyl ether (DME)-powered heavy-duty commercial vehicles in North America, with limited production beginning in 2015.

Air pollution from sources such as transport and agriculture is still being emitted above legal limits in 10 European Union (EU) Member States according to new data published by the European Environment Agency (EEA). The EU-28 as a whole did not exceed its aggregated emission ceilings for any of the four air pollutants in 2014.
A study by researchers from the US, Mexico and Canada has found that children’s urban air pollution exposures result in systemic and brain inflammation and the early hallmarks of Alzheimer’s disease (AD). The study found that clinically healthy children who live in a polluted environment and who also carry a gene—the apolipoprotein ?
In a paper published in the American Journal of Respiratory and Critical Care , researchers report that children exposed to higher levels of air pollution—even if relatively low—including fine particulate matter (PM 2.5 ) and soot (black carbon), had worse lung function than those living in less polluted areas. mL; -43.9,
The California Air Resources Board (ARB) has released , for public review, a concept paper to initiate discussion on the development of a Short-Lived Climate Pollutant Reduction Strategy. Short-lived climate pollutants (SLCPs) include methane, tropospheric ozone, black carbon, and fluorinated gases.
An international team of researchers has used satellite images to map urban growth between 1985 and 2015. Urban area dynamics during 1985–2015 at the global and continent scales. They then extracted cells from the two fusion maps that changed from non-urban in 1985 to urban in 2015.
They also contribute to air pollution that harms the health of billions of people worldwide and reduces agricultural yields. Maintaining separate reporting methods for each pollutant would provide a clearer understanding of the benefits associated with SLCPs’ reduction. Lead author Drew T. Resources. Shindell, N. Borgford-Parnell, M.
This project was initiated in 2015 and was funded by the European Union through the Horizon 2020 and Innovation Program. This project demonstrates that today we can replace fossil fuel thermal drives with clean energy, and thus contribute to the fight against global warming and pollution for the well-being of our communities.
In April, the committee had approved a draft law setting out a new CO 2 target for cars of 95 g CO 2 /km (153 g/mile) by 2020, down from 130 g CO 2 /km (209 g/mile) in 2015—a reduction of 27% from the 2015 target. Earlier post.). Super credits assign a favorable weighting to vans that emit less than 50 g/km of CO 2.

The mode of travel you take on your daily work commute can make a big difference in your exposure to air pollution, according to a new study by researchers at the California Air Resources Board (ARB). The study took place from April 2014 to November 2015 and encompassed 161 individual commutes.
The primary regulated air pollutants (criteria pollutants) are particulate matter (PM), nitrogen oxides (NO x ), carbon monoxide (CO) and volatile organic compounds (VOCs). Hydrocarbons are key precursors to two priority air pollutants, ozone and particulate matter. 15, 9983-9996, doi: 10.5194/acp-15-9983-2015.
The effect of near roadway air pollution on human health is especially significant in major cities, and respiratory and cardiovascular diseases are mostly implicated in response to continued/repeated exposure to air pollution. The paper appears in the ACS journal Environmental Science & Technology. —Pardo et al. 5b01449.
While the study finds an association between air pollution and atherosclerosis, researchers aren’t clear on why. For policy in the US, the focus should be on how to effectively control ozone concentration, which may be harder because it’s a secondary pollutant. —Meng Wang. —Meng Wang. Meng Wang, Paul D. Sampson, Lianne E.
