NOAA, partners find about 98% decline in VOCs concentrations in LA Basin over last 50 years despite 3x increase in use of gasoline and diesel

Green Car Congress

In California’s Los Angeles Basin, levels of volatile organic compounds (VOCs) pollutants have decreased by about 98% since the 1960s, even as area residents now burn approximately three times as much gasoline and diesel fuel. The reason is simple: cars are getting cleaner. The difference was amazing.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. As transportation gets cleaner, those other sources become more and more important. You don’t do this with gasoline.

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles.

Transient Plasma Systems says advances are bringing plasma ignition technology closer to commercialization

Green Car Congress

Advanced ignition technologies, such as those offered by TPS, have been widely recognized as enablers to achieving higher combustion efficiency and lower emissions for gasoline-powered engines. We feel confident that our technology is ready to usher in the benefits of lower emissions, and lead the industry’s push toward cleaner mobility.

Plug-in Hybrid Study: Electricity Better

Plugs and Cars

And the grid is getting cleaner and more renewable every year. Use of electricity reduces both gasoline consumption and emissions—starting emissions, refueling emissions, running emissions and even upstream refinery emissions. Cumulative GHG emissions reductions from 2010 to 2050 can range from 3.4 billion metric tons.

The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.

ARB releases proposed cap-and-trade regulation for comment; transportation fuels impacted in 2015

Green Car Congress

ARB staff reviewed four offset protocols and recommends that they be approved as part of this regulatory package: (1) the Urban Forest Projects Protocol; (2) the US Ozone Depleting Substances Projects Protocol; (3) the Livestock Manure (Digester) Projects Protocol; and (4) the US Forest Projects Protocol. Offset Protocols.
