Those who flew in 2020 had twice the environmental impact of those in 2019

Green Car Congress

The energy intensity of a transportation mode is calculated by dividing the amount of fuel used by the number of passenger miles traveled and converting the result into a common measure—Btu (British thermal units) per passenger mile traveled. Energy intensities of flying and driving, in Btu per passenger mile. Certificated air carriers.

Study finds light-duty gasoline vehicles responsible for about about half of PM2.5 mass, 14% of PM10 in road tunnel

Green Car Congress

Researchers led by a team from the University of Houston have characterized the platinum group elemental composition of PM 2.5 and PM 10 emissions—mainly from gasoline-fueled light-duty vehicles (LDVs)—in the Washburn Tunnel in Houston Texas as a mechanism for better determining the contribution of LDVs to particulate emissions.

Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

In 2013, the Cummins-led team demonstrated a Tier 2 Bin 5 version of the engine on the dyno, and then on a vehicle, while development of the Tier 2 Bin 2 engine started. The HC/NO x release temperature in a cold start catalyst is high enough that the released HC/NO x can be further converted by the downstream catalytic components.

Researchers use LCLS to get real-time view of chemical reaction; important insight into how catalysts work

Green Car Congress

Catalytic converters in cars, for example, reduce emissions by converting exhaust to less toxic compounds. Located in Menlo Park, California, SLAC is operated by Stanford University for the US Department of Energy Office of Science.
