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

Green Car Congress

In a paper published in the journal Atmospheric Environment , they report on the findings from a suite of scenarios designed to quantify the effect of both the magnitude of EV market penetration and the source of electricity generation used to power them.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet.

HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols. In Asia, in particular, high temperatures, humidity, solar radiation and the frequency of storms play a major role.

Why Schools Should Electrify Their Bus Fleets

Blink Charging

Even with a flurry of activity and available funding, though, only about 1% of school buses in the country are currently electric ( matching the approximate percentage of cars and light duty trucks on the road that are electric ). Here are several reasons for school districts to switch to electric buses.

International study of role of soots impact on Arctic climate

Green Car Congress

Carbon is dark in color and absorbs solar radiation, much like wearing a black shirt on a sunny day. If you want to be cooler, you would wear a light-colored shirt that would reflect the sun’s warmth. Aboard each aircraft will be a package of instruments to measure aerosol size, number, light absorption and chemical composition.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Soot—black and brown particles that absorb solar radiation—comes from two types of sources: fossil fuels such as diesel, coal, gasoline, jet fuel; and solid biofuels such as wood, manure, dung, and other solid biomass used for home heating and cooking around the world. Jacobson is a senior fellow at the Woods Institute for the Environment.
