Why Schools Should Electrify Their Bus Fleets

Blink Charging

In addition, other studies have shown that increases in PM 2.5 , NO 2 , and ozone were associated with lower test scores that were “equivalent to the effects of short-term reductions of thousands of dollars in district median household income.” View the Case Study How much funding is available for EV charging at school districts?

Argonne researcher using hydrous ethanol as a dual fuel to lighten the carbon footprint of locomotives

Green Car Congress

The first is the Vehicle Technologies Office (VTO), which aims to advance combustion engine technology and simultaneously reduce criteria emissions, such as carbon monoxide, nitrogen oxides and ozone. Adapting existing fleets is a compelling issue for rail. Locomotives have extremely long service lives.

EPA proposes new heavy-duty truck emissions rules

Green Car Congress

The proposed multi-pollutant rule would further reduce air pollution from heavy-duty engines and vehicles across the United States, including ozone and particulate matter (PM). In 2045, the proposed Option 1 would result in total annual monetized ozone- and PM 2.5

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

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. —Cliff et al. the products used for “car care,” such as windshield washer fluid.

Texas study finds PHEV use could increase ozone at night, decrease ozone during the day

Green Car Congress

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours.

CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The twenty light-duty gasoline vehicles included a mixture of technologies, such as gasoline direct injection (GDI), port fuel injection (PFI) as well as PFI+GDI fuel systems that are representative of the current California gasoline fleet. The test fleet showed statistically significant effects for some pollutants, but not for others.

Study: 25% EV adoption would save US $17B annually from avoided climate change & pollution damages

Green Car Congress

Vehicle electrification in the United States could prevent hundreds to thousands of premature deaths annually while reducing carbon emissions by hundreds of millions of tons. In the new study, Horton, Peters and their team looked at vehicle fleet and emissions data from 2014. Results show that in more aggressive scenarios—i.e.,
