Error bars for bus and rail emissions represent variability among cities. Source: UCS.
The company’s new Advanced Air Cleaner technology comes with a sensor that measures PM 2.5 Available on all 90 and 60 Series Volvo models based on the Scalable Product Architecture (SPA) since this spring, the Advanced Air Cleaner cleans out fine particulate matters from the cabin. In China, where PM 2.5
The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions.

This is important for policymakers when forecasting and influencing future emissions paths in the context of climate change.
For travelers who visit cities with high levels of air pollution, even a short stay leads to breathing problems that can take at least a week from which to recove, a new study led by researchers at NYU School of Medicine finds. Researchers then compared the health data against levels of air pollution collected from local government agencies.
in 2030 even if India were to comply with its existing pollution control policies and regulations. However, aligning sustainable development policies to the implementation of advanced emission control technologies could provide NAAQS-compliant air quality to about 85% of the Indian population. levels by 20-30% over the next five years.
Heavy-duty trucks can emit drastically higher levels of pollution when not equipped with required emissions controls. Transport companies must comply with California’s rule to improve air quality and protect adjacent schools and communities from breathing these toxic pollutants. The company, headquartered in Thomasville, N.C.,

Diesel generators release greenhouse gases, particulate matter (PM), volatile organic compounds (VOCs), nitrous oxides (NO x ) and sulfur dioxide (SO 2 ), harmful pollutants that create smog and exacerbate respiratory conditions. Emissions from these backup generators can harm local residents, regional air quality and the global climate.
The Mayor confirmed his plan at Transport for London’s (TfL’s) “New Taxis for London” event, at which he met five manufacturers developing zero emission capable taxis—Frazer-Nash, Nissan, Karsan, London Taxi Company and Mercedes-Benz. Last year the Mayor pledged to introduce an Ultra Low Emission Zone in central London by 2020.
The air in the United States and Western Europe is much cleaner than even a decade ago. Despite these successes, sulfate levels in the atmosphere have declined more slowly than sulfur dioxide emissions, especially in wintertime. This does not mean that the emissions reductions aren't working.
Consumer products such as shampoo, cleaning products and paint now contribute as much to emitted volatile organic compounds (VOCs) in cities as tailpipe emissions from vehicles, according to a new study led by NOAA. Total VOC emission factors for end uses of petrochemical sources in the study. —McDonald et al.
That insight could also help the car industry make cleaner combustion engines. The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. Zhao et al. This work was supported by the DOE Office of Science.
EPA has implemented standards that require diesel engines to be more than 90% cleaner, but many older diesel school buses remain in operation and predate these standards. Older diesel engines emit large amounts of pollutants, such as nitrogen oxides and particulate matter.
It is the only diesel engine operating on the road capable of meeting CARB’s 2027 regulation, which requires a 90% reduction in emissions of NO x compared to current standards. This mode is used when the aftertreatment system is not yet active to make sure the tailpipe emissions remains very low. Achates Power announced that the 10.6-liter,

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions.
AB 1346 would require new sales of SORE to be zero-emission by 2024 or whenever the California Air Resources Board (CARB) determines is feasible, whichever is later. Today, operating the best-selling gas-powered commercial leaf blower for one hour emits air pollutants comparable to driving a 2017 Toyota Camry from Los Angeles to Denver.
