Chan School of Public Health.
In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.

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.
Members of the European Parliament’s Environment, Public Health and Food Safety Committee approved a draft law setting out rules for achieving a 147 g CO 2 /km (235 g/mile) target for new light commercial vehicles by 2020, down from 203 g/km (325 g/mile) today—i.e., The vote was 53 to 4 with 1 abstention. Earlier post.).

Yale researchers found that common road and roofing asphalts produced complex mixtures of organic compounds, including hazardous pollutants, in a range of typical temperature and solar conditions.
The reasons were two-fold: (i) increased air pollution led to households staying indoors more to mitigate the pollution impact; and (ii) PM 2.5 pollution led to the closing of windows, and running of air-conditioners and air purifiers more intensively either to reduce indoor particle levels or provide relief from indoor heat.

Sharma and Kumar (2020). 2020) “Quantification of air pollution exposure to in-pram babies and mitigation strategies.”
finds that private jets are 10 times more carbon-intensive than airliners on average, and 50 times more polluting than trains in terms of CO 2 emitted per passenger-km. By August 2020, while most Europeans were still grounded and commercial flights were down 60% year-on-year, private jet traffic had returned to pre-COVID levels.
Researchers at the University of California, Davis, have found a link between traffic-related air pollution and an increased risk for changes in brain development relevant to neurodevelopmental disorders. The researchers compared the brains of rat pups exposed to traffic-related air pollution with those exposed to ?ltered ltered air.
California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then.
A new study finds that automated pollution monitors in China led to more accurate readings and that citizens used this information to protect themselves better against the harms of air pollution. The central government knew it needed to improve air quality, but that it would be impossible without knowing true pollution levels.
The California Air Resources Board will consider the proposed Heavy-Duty Low NO x Omnibus Regulation on 27 August 2020. The proposed regulation is intended to ensure reductions in smog-forming NO x and protect communities most impacted by air pollution. On-road heavy-duty vehicles are an essential part of the state’s economy.
Spain, Italy, Greece, France and Norway are the most exposed countries to cruise ship air pollution in Europe. Among the major cruise ports, Barcelona, Palma Mallorca and Venice are the most polluted. In Denmark, for example, whose coasts are entirely within SECAs, cruise ships emitted 18 times more SO x in 2017 than all 2.5

In efforts to scale EV charging infrastructure to support the expected rise of electric vehicles on the road, the UK government is set to increase the number of high-powered rapid chargepoints in England from 809 (as of 1 January 2020) to 6,000 by 2035. This growth will require high megawatt capacities across England’s road networks.
Meeting standards for fine particle pollution, or PM 2.5 , is the San Joaquin Valley’s most critical air quality challenge. The San Joaquin Valley has the worst particulate matter pollution in California—and the worst in the nation for annual federal standards. The 2020 deadline is for both 1997 standards.).
EPA’s TAG program aims to reduce air pollution in areas of the nation with the highest levels of ambient ozone and fine particulate matter (PM 2.5 ) pollution. Under the TAG program, eligible state and local air pollution control agencies must directly apply to EPA, but can select partners for a project consortium.

The Mayor of London, Boris Johnson, has renewed calls for scrapping the most polluting diesel cars and giving drivers cash incentives to switch to cleaner vehicles as part of the evidence he gave to the Environmental Audit Committee today. They now feel very hacked off now they’re told they are more polluting.
Large improvements of air quality in China during the lockdown have been widely reported, but new research shows that two pollutants harmful to human health—fine particulate matter (PM 2.5 ) and ozone—were only slightly reduced. Much smaller reductions were observed for other pollutants.
This brief study analyzes, for each individual state, the changes from 2018 to 2020 in the use of coal (one of the two most polluting energy sources) to generate electricity. In 2020, only two states used oil to generate more than 3% of the electricity: 66% in Hawaii and 16% in Alaska.) from coal. West Virginia. West Virginia.
The use of electric buses on urban routes reduced the emissions of pollutants into the air of Moscow by 40 thousand tons in 2020. Moscow is already a leader among European capitals in having an eco-friendly surface transport fleet. By the end of 2021 there will be 1000 electric buses on duty. tons per year.

Moreover, to comply with IMO’s 2020 global sulfur limit, ships must either switch from HFO to more expensive very low sulfur fuel oil (VLSFO) or use HFO with a scrubber, if they have one installed. Nikita Pavlenko, Bryan Comer, Yuanrong Zhou, Nigel Clark, Dan Rutherford (2020) “ The climate implications of using LNG as a marine fuel ”.
This version of the vehicle we started in 2020, so to have passed all certification tests in this short time frame is a truly monumental achievement by the whole team. The rapid growth of e-commerce has led to an increase in demand for light commercial transport in cities, increasing both congestion and pollution.
Car users from the world’s least affluent cities are exposed to a disproportionate amount of in-car air pollution because they rely heavily on opening their windows for ventilation, according to a new global study led by researchers at the University of Surrey. This is yet a distant dream in many ODA countries. El-Gendy, A., Mamuya, S.H.,
Under its pollution prevention treaty (MARPOL), the International Maritime Organization (IMO) adopted mandatory measures to reduce greenhouse gas emissions from international shipping: the Energy Efficiency Design Index (EEDI) and the Ship Energy Efficiency Management Plan (SEEMP).
