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.

New Comprehensive Lifecycle Energy and Emissions Inventory Includes Non-Operational Components; Large Aircraft Can Perform Better than Light Rail

Green Car Congress

Inventorying criteria air pollutants showed that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 Of the non-road modes (rail and air), light aircraft showed the worst performance per PKT. Chester and Horvath (2009). Click to enlarge.

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

Jacobson used a computer model of global climate, air pollution and weather that he developed over the last 20 years and updated to include additional atmospheric processes to analyze how soot can heat clouds, snow and ice. Black carbon can also absorb light reflecting from the surface, which helps make it such a potent warming agent.

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. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. —Drew Shindell.
