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

Green Car Congress

The levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. These emissions are independent of the vehicle energy/propulsion system and therefore applicable to all road vehicle types including those with battery-electric powertrains. Cliff et al.

San José International deploys 10 Proterra electric buses in airport fleet

Green Car Congress

Mineta San José International Airport’s (SJC) has deployed a fleet of 10 Proterra battery-electric buses that will transport passengers and their luggage between SJC’s parking lots, rental car center, and terminals. The electric bus fleet is anticipated to reduce ozone emissions by 1.1

MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. We quantify the effects of these trade-offs in terms of emissions reduction and fuel burn increase using representative engine cycle models provided by a major aero-gas turbine manufacturer.

PSI team develops web tool for consumers to compare environmental impact of passenger cars in detail

Green Car Congress

Deterioration of the ozone layer [kg CFC-11-eq.]. A recent PSI study led by environmental scientist Christian Bauer found that a battery electric car is already the most environmentally friendly option in Switzerland and many other countries, even when the manufacture of the battery is figured in.

Eaton introduces set of products to reduce vapor emissions during refueling; LEV III regulations

Green Car Congress

This problem is even more pronounced in hybrid-electric vehicles, which require special measures to address evaporative emissions as the gas engine only operates intermittently, creating the need to store pressurized fuel vapor. A Fuel Tank Isolation Valve is offered for use in hybrid electric vehicles.

USDOT FTA announces $182M in Low-No grants for transit vehicles & facilities nationwide

Green Car Congress

The project selections were approved as part of the Low- or No-Emission (Low-No) Grant program, which funds the deployment of zero-emission and low-emission transit buses and supporting equipment and facilities. By retrofitting the garage to service electric buses, the agency will also lower pollution in the surrounding community.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. These programs cover transportation fuels, industrial emissions, vehicle emissions and emissions from electricity generation.
