The Shenzhen e6 Taxi fleet has now accumulated ~1,730,000 all-electric miles (2.77
I recently read a brilliant book, Malcolm Gladwells, Revenge of the Tipping Point that alerted me to the fact that just five per cent of the passenger vehicles on the road produce more than half of all the pollution in the air. Pollution would drop by the same amount as the 10 per cent shift.
The green symbol and dashed arrow illustrate the large reductions in tailpipe VOC emission factors as precatalyst on-road gasoline vehicles were replaced by present-day vehicle fleets. Even so, lotions, paints and other products contribute about as much to air pollution as does the transportation sector. McDonald et al.
What isn’t often discussed is the potential for EVs to reduce noise pollution. With that in mind, here’s a closer look at EVs and their impact on noise pollution. How Are Automakers Reducing Noise Pollution? Reducing pollution starts with EV production. Reduced noise and air pollution are excellent public health outcomes.

The dual-fuel diesel-biomethane powered bus is expected to reduce pollutant emissions and greenhouse gas emissions by around a half. Dual-fuel use is a very attractive option.
The primary regulated air pollutants (criteria pollutants) are particulate matter (PM), nitrogen oxides (NO x ), carbon monoxide (CO) and volatile organic compounds (VOCs). Hydrocarbons are key precursors to two priority air pollutants, ozone and particulate matter. —Dunmore et al.
A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. The magnitude of the drop in VOC levels was surprising, even to researchers who expected some kind of decrease resulting from California’s longtime efforts to control vehicle pollution. ppbv/ppmv to 10.7
Obama was delivering a speech on energy policy at Georgetown University. We have to discover and produce cleaner, renewable sources of energy with less of the carbon pollution that threatens our climate. The fleet of cars and trucks we use in the federal government is one of the largest in the country. —President Obama.
FXI) announced the addition of 11 new ultra-low emission natural gas trucks to the FXI fleet. Funding was received from the Prop 1B program administered by the San Joaquin Valley Air Pollution Control District and the California Hybrid and Zero-Emission Truck and Bus Voucher Incentive Program (HVIP). Southern California Gas Co.

Pollutant concentrations were measured at high time resolution in the exhaust plumes of more than a thousand drayage trucks as they drove toward the Port on a major access road.
A study by a team from the University of British Columbia and Metro Vancouver suggests that optimized operational control strategies for transit bus fleets ultimately offer transit agencies a way to maximize the benefits of their capital investments in new, cleaner technologies. the contact of pollutants and people in space and time).
Using biodiesel in construction vehicles offers promising environmental benefits in terms of reduced tailpipe emissions as well as reductions in fuel cycle emissions of selected pollutants, according to a new study by researchers at North Carolina State University. Seven scenarios were used in the LCI analysis.
Electric vehicles are pretty much inevitable at this point, with carmakers, led by all-EV disruptors such as Tesla, transitioning their respective fleets to electric. This disparity highlights an opportunity to address environmental justice in communities that are disproportionately impacted by pollution and its associated health issues.
