Port of Los Angeles surpasses 2023 pollution reduction targets five years ahead of schedule; NOx down 60% from 2005

Green Car Congress

Emissions of NO x , a key component of smog, at the Port of Los Angeles are down 60% compared to 2005 emissions levels. The newly released 2017 Inventory of Air Emissions shows the Port set new record lows for emissions reductions while its container volume reached an all-time high of 9.34

In-use measurements of NOx and particulates trends for heavy-duty vehicles in California

Green Car Congress

A team at the University of Denver has measured the emissions from two in-use California heavy-duty truck fleets—at the Port of Los Angeles and the Cottonwood weigh station in Northern California—using the On-Road Heavy-Duty Measurement System in 2013, 2015 and 2017. 87%), black carbon (?76%),

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

Green Car Congress

An aerial methane survey conducted by the California Air Resources Board (CARB), California Energy Commission (CEC) and NASA has found that just 10% of the point sources were responsible for 60% of the total methane emissions detected. Those 30, however, were responsible for 40% of the total point source emissions detected during the survey.

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.
