Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

For example, states in the western US (WUS) generally produce a larger fraction of their electricity from renewable and/or “emission-free” sources (i.e., Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. coal, oil, natural gas, and biomass).

ARB posts discussion draft of new proposed mobile-source emissions reduction strategy through 2030; Advanced Clean Cars 2 regulation

Green Car Congress

ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 Projected statewide light duty vehicle technology mix. The electrical grid and hydrogen supply supporting these electric vehicles will need to represent 50% renewable energy generation.

Why Schools Should Electrify Their Bus Fleets

Blink Charging

Even with a flurry of activity and available funding, though, only about 1% of school buses in the country are currently electric ( matching the approximate percentage of cars and light duty trucks on the road that are electric ). Here are several reasons for school districts to switch to electric buses.

New Comprehensive Lifecycle Energy and Emissions Inventory Includes Non-Operational Components; Large Aircraft Can Perform Better than Light Rail

Green Car Congress

Ranges in passenger occupancy can easily change the relative performance of modes, with large aircraft performing better than light rail in some of the areas investigated. Samples of the findings include: Off-peak urban diesel buses has the largest energy consumption and GHG emissions per PKT, followed by the three light-duty vehicles.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

The report, “ Environmental Assessment of a Full Electric Transportation Portfolio ”, is based on a projection that by 2050 electricity replaces traditional fuels for approximately half of light- and medium-duty transportation and a significant portion of non-road equipment.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.

Report argues advanced HD natural gas vehicles foundational for California to hit air and climate goals; near zero-emission potential

Green Car Congress

These technologies include, but are not limited to, advanced aftertreatment and waste heat recovery; lean-burn plus lean-NO x emissions traps; integration of zero-emission miles technologies; further refinements in reducing friction and parasitic energy losses; and widespread utilization of renewable and natural gas and hydrogen blends.
