2015 Diesel Ozone Pollution 
Green Car Congress
DECEMBER 27, 2020
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 problem is being created by the change in chemistry between NO x and O 3.

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment.

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London. —Dunmore et al. Dunmore et al.

A new international study has found that laboratory tests of nitrogen oxide emissions from diesel vehicles significantly underestimate the real-world emissions by as much as 50%. For light-duty vehicles, such as passenger cars, trucks, and vans, the European Union produced nearly 70% of the excess diesel nitrogen oxide emissions.

The At-Berth Regulation is a critical tool for CARB to cut harmful toxic diesel emissions from ships docked in California ports, and we hope this penalty will send a message that violators will pay a hefty price if they fail to comply. The goal of CARB’s At-Berth Regulation is to reduce diesel emissions from ocean-going vessels (OGVs).

NO x emissions have not been decreasing as expected in recent years (2011–2015) when comparing top-down estimates from satellites and surface NO 2 measurements to the trends predicted from the US Environmental Protection Agency’s emission inventory data, according to a new study by an international team of researchers.
