JUNE 8, 2023

A fleet average nonfuel nonexhaust VOC emission factor of 58 ± 39 mg veh –1 km –1 was calculated for the missing source, which is greater than the total of all VOCs emitted from vehicle exhausts and their associated evaporative fuel losses. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

AUGUST 21, 2009

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming. Jacobson found that the combination of the two types of soot is the second-leading cause of global warming after carbon dioxide. Particle traps filter out soot particles from exhaust fumes.

NO 2 is just one component of air pollution, which is made up of many pollutants (including particulate matter, ozone, carbon monoxide), which are known to have numerous adverse effects on health. The researchers estimate that most children lived in areas below the current WHO guideline of 21 parts per billion for annual average NO 2.
