Argonne researcher using hydrous ethanol as a dual fuel to lighten the carbon footprint of locomotives

Green Car Congress

El-Hannouny’s research is funded by two different DOE offices in the Office of Energy Efficiency and Renewable Energy (EERE). The first is the Vehicle Technologies Office (VTO), which aims to advance combustion engine technology and simultaneously reduce criteria emissions, such as carbon monoxide, nitrogen oxides and ozone.

UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said. Click to enlarge. °C (within a likely range of 0.2-0.7

WHO issues new, lower Global Air Quality Guidelines for classical pollutants

Green Car Congress

When action is taken on these classical pollutants—particulate matter (PM), ozone (O?), and carbon monoxide (CO)—it also has an impact on other damaging pollutants. PM is primarily generated by fuel combustion in different sectors, including transport, energy, households, industry, and from agriculture.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

These emissions are independent of the vehicle energy/propulsion system and therefore applicable to all road vehicle types including those with battery-electric powertrains. —Cliff et al. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

NASA’s Orbiting Carbon Observatory 2 reaches orbit

Green Car Congress

At 2:56 AM PST today, NASA’s Orbiting Carbon Observatory 2 (OCO-2) was successfully launched into orbit from Space Complex 2 West at California’s Vandenberg Air Force Base, riding on a two-stage Delta II 7320-10 launch vehicle. by Jack Rosebro. This measurement is unique like a fingerprint, and can be used for identification.

Study: 25% EV adoption would save US $17B annually from avoided climate change & pollution damages

Green Car Congress

replacing 75% of cars with electric vehicles and increasing renewable energy for every generation—savings could reach as much as $70 billion annually. Vehicle electrification in the United States could prevent hundreds to thousands of premature deaths annually while reducing carbon emissions by hundreds of millions of tons.

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels. Locations with clean energy sources, however, saw reductions. Jordan L.
