Pollution plumes in Paris air are richer in gaseous aromatic compounds than in LA; gasoline engines main source of VOCs

Green Car Congress

The study also shows that the proportion of gaseous aromatic compounds—apart from benzene—in hydrocarbon emissions is two to three times greater in pollution plumes in Paris than in Los Angeles, even though the total quantity of hydrocarbons emitted in Los Angeles remains considerably greater than in Paris.

Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

Green Car Congress

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.

Aerial methane survey finds a fraction of point sources responsible for more than a third of California’s methane emissions

Green Car Congress

Los Angeles and Ventura Counties were next on the list. In response to methane’s significant contribution to the state's emissions and the requirements of Senate Bill 1383, California is taking a number of other steps to reduce methane emissions from various sources as part of the Short-lived Climate Pollutant strategy.

CARB approves $423M plan to mitigate harm from Volkswagen defeat devices; significant investments in heavy-duty vehicles and equipment sectors

Green Car Congress

The California Air Resources Board (CARB) approved a plan to mitigate statewide harm from more than 10,000 tons of smog-causing pollutants released in the state due to Volkswagen’s (VW) use of illegal “defeat devices” in diesel passenger cars. As designed, the plan approved today invests about 50% of the available funds in those communities.

ICCT-sponsored study of in-use testing of 3 Tier2-Bin5, CA LEV-II light-duty diesels finds wide variation of emissions against the limits

Green Car Congress

The International Council on Clean Transportation (ICCT) contracted with the Center for Alternative Fuels, Engines and Emissions at West Virginia University to conduct in-use testing of three light-duty diesel vehicles (two 2.0L diesels and one 3.0L diesel) over pre-defined test routes exhibiting diverse driving conditions.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities.
