Trends in life cycle greenhouse gas emissions of future light duty electric vehicles [PDF]

, 2020
The majority of previous studies examining life cycle greenhouse gas (LCGHG) emissions of battery electric vehicles (BEVs) have focused on efficiency-oriented vehicle designs with limited battery capacities.

Long-term U.S transportation electricity use considering the effect of autonomous-vehicles: Estimates & policy observations [PDF]

, 2018
In this paper, we model three layers of transportation disruption – first electrification, then autonomy, and finally sharing and pooling – in order to project transportation electricity demand and greenhouse gas emissions in the United States to 2050 ...

Current vehicle emission standards will not mitigate climate change or improve air quality

Scientific Reports, 2023
The vehicle emissions testing programme was conducted by the UK Department of Transport in 2016 in response to emissions tampering exposed in the Volkswagen (VW) emissions scandal. The programme identified large emissions discrepancies between real-world

High-resolution mapping of vehicle emissions of atmospheric pollutants based on large-scale, real-world traffic datasets

Atmospheric Chemistry and Physics, 2019
. On-road vehicle emissions are a major contributor to elevated air pollution levels in populous metropolitan areas. We developed a link-level emissions inventory of vehicular pollutants, called EMBEV-Link (Link-level Emission factor Model for the ...

On-road vehicle emissions and their control in China: A review and outlook.

Science of the Total Environment, 2017
The large (26-fold over the past 25years) increase in the on-road vehicle fleet in China has raised sustainability concerns regarding air pollution prevention, energy conservation, and climate change mitigation.

Measurement of vehicle particulate emissions. [PDF]

Environmental Health Perspectives, 1975
A constant volume sampler (CVS) compatible auto exhaust particulate sampling system has been built which samples exhaust isokinetically at constant temperature. This system yields internally consistent results and is capable of frequent and convenient operation.

Fortifying casein phosphopeptides and Ca in wheat reduces the As, Cd, and Pb bioavailability based on a mouse model: Calcium and phosphate transporters and gut microbiota

Soil & Environmental Health
Reducing the oral bioavailability of metal contaminants including As, Cd, and Pb in foods can protect human health. Studies showed reduced metal bioavailability with elevated Ca and Fe intake; however, the effectiveness of enhancing food Ca and Fe ...

PM2.5 exposure disparities persist despite strict vehicle emissions controls in California

Science Advances
As policymakers increasingly focus on environmental justice, a key question is whether emissions reductions aimed at addressing air quality or climate change can also ameliorate persistent air pollution exposure disparities.

The greenhouse gas emissions of an electrified vehicle combined with renewable fuels: Life cycle assessment and policy implications

, 2021
A life cycle assessment is presented for a current vehicle’s greenhouse gas impact when using a combination of electrification and renewable fuels. Three degrees of electrification are considered: a hybrid electric vehicle, a plug-in hybrid electric ...
