Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. New research led by the University of Washington (UW) is the first to measure this phenomenon’s effect over years and at a regional scale. Michael Diamond/University of Washington.

Satellite study suggests California clean air regulations working to reduce PM2.5 emissions in state

Green Car Congress

Scientists from Emory University, NASA’s Jet Propulsion Laboratory and the California Air Resources Board teamed to analyze satellite data to determine the 15-year trend of PM 2.5 pollution in the state. is especially burdensome in California and accounts for the greatest percentage of health impacts attributable to air pollution.

Study estimates California’s GHG reductions since 2003 could be wiped out by 2020 wildfires

Green Car Congress

In an open-access report in the journal Environmental Pollution , researchers from UCLA and the University of Chicago estimate that California’s wildfire carbon dioxide equivalent (CO 2 e) emissions from 2020 (~127 mmt CO 2 e ) are approximately two times higher than California’s total greenhouse gas (GHG) emission reductions since 2003.

Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7

Congestion charge and electric vehicles: Everything you need to know

Drive Electric

Faced with the rising threat of climate change, one of the government’s first major steps to combat dangerous levels of carbon dioxide emissions in the country was introduce the Congestion Charge. The London Congestion Charge was first introduced in 2003. You only have to look to the London Congestion Charge for proof of that.

Study of lead isotopes provides insight into aerosols transport from Asia to US

Green Car Congress

About a third of the airborne lead particles collected at two sites in the San Francisco Bay Area came from Asia, a finding that underscores the far-flung impacts of air pollution and heralds a new way to learn more about its journey across vast distances. They found that a median value of 29% of the lead particles were of Asian origin.
