Researchers present new explanation for the long-range transport of PAH pollutants

Green Car Congress

When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).

EPA issues updated air pollution standards for oil and natural gas production; first federal rules for fracked natural gas wells

Green Car Congress

In response to a court deadline, the US Environmental Protection Agency (EPA) has finalized standards to reduce air pollution associated with oil and natural gas production. When natural gas is produced, some of the gas escapes the well and may not be captured by the producing company. Methane 1.0 equivalent (CO 2 e)].

How much do electric cars really pollute, even without tailpipes?

Green Car Reports

But there's no escaping that manufacturing these vehicles, driving them for 10 years or more, and then disposing of them creates pollution that has a wide range of negative impacts. Personal automobiles have given hundreds of millions of people the great luxury of a convenient and comfortable mode of transportation.

UC Davis Begins $2.8M Studies on Impacts of Escaped Nitrogen

Green Car Congress

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The burning of coal releases more carbon dioxide than other fossil fuels, as well as comparatively high levels of other pollutants, including sulfur dioxide, nitrogen oxides, and particles such as ash.

DOE awards $35M to 12 ARPA-E projects to reduce methane emissions; 5 on natural gas engines

Green Car Congress

Marquette University will enable an innovative combustion technology for lean-burn (high air-fuel ratio) natural gas engines to potentially reduce the amount of methane slip—or methane in the inlet fuel stream that escapes to the atmosphere—to 0.25% of the inlet fuel stream.

We Don’t Need a Jetsons Future, Just a Sustainable One

Cars That Think

Where we could manage and then reduce the amount of carbon in our atmosphere? Much of the motivation behind building new rockets or developing colonies on Mars is wrapped up in the rhetoric of our warming planet being something to escape from. What about reducing pollution in urban and poor communities?
