California “gasoline superuser” bill advances; focusing ZEV incentives on reducing gasoline use

Green Car Congress

By shifting the biggest gasoline users into ZEVs first, AB 2816 also reduces the total number of ZEVs that would be needed to reach the state’s near-term target of cutting light-duty vehicle emissions in half by 2030. California’s biggest gasoline users currently are on track to be the last people to switch to ZEVs.

T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

Green Car Congress

E-fuels are made by combining green hydrogen with CO 2 to produce liquid fuel that can be similar to gasoline or diesel used in conventional engines (as well as kerosene used in aviation). The emissions were compared to the standard E10 EU gasoline. However, said T&E, particle pollution was far from eliminated.

MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. Ethanol or methanol would be employed to increase knock resistance. —Cohn and Bromberg (2019).

Study explores impact of changing gasoline and diesel taxes in Europe

Green Car Congress

Diesel is currently taxed at a lower level than gasoline in Europe; however, since 2011 the EC has been considering reversing that situation by making energy taxes systematically reflect the CO 2 performance of the energy product. A scheme including a decreased gasoline tax could bring about an increase in CO 2 emissions.

New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

Tailpipe emissions are falling over time, as exhaust filters become more efficient and with the prospect of extending the measurement of particulates under the potential future Euro 7 regulation, while tire wear emissions are rising as vehicles become heavier and added power and torque is placed at the driver’s disposal.

NIH study links air pollution to increase in newborn intensive care admissions

Green Car Congress

Infants born to women exposed to high levels of air pollution in the week before delivery are more likely to be admitted to a newborn intensive care unit (NICU), suggests an analysis by researchers at the US National Institutes of Health (NIH). Short-term exposure to most types of air pollutants may increase the risk for NICU admission.
