Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon. —Mark Jacobson.

Study: plant roadside hedges rather than trees to combat near-road pollution

Green Car Congress

Urban planners should plant hedges—or a combination of trees with hedges—rather than just relying on roadside trees if they are most effectively to reduce pollution exposure from cars in near-road environments, according to a new study from the University of Surrey. The best way to tackle pollution is to control it at the source.

Two-year study in Canada finds large trucks disproportionately contribute to higher levels of black carbon pollution

Green Car Congress

A two-year study led by researchers at the University of Toronto has found large trucks to be the greatest contributors to black carbon emissions close to major roadways. This was in part due to differences in wind and proximity to the road but, surprisingly, the number of vehicles didn’t make that much of a difference. Jonathan M.

Study links PM2.5 pollution with millions of preterm births globally

Green Car Congress

Recent research has suggested that exposure to air pollution could also be a risk factor. exposures, inclusion of provider-initiated preterm births, and exposure to indoor air pollution. There are many known risk factors for preterm birth—from the mother’s age, to illness, to poverty and other social factors. Malley et al.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. and China account for more than half of all carbon dioxide emissions globally.

Study first to quantify amount of US pollution resulting from Chinese manufacturing for exports

Green Car Congress

Average annual percentage of black carbon pollution related to Chinese exports. Dust, ozone and carbon can accumulate in valleys and basins in California and other Western states. We’ve outsourced our manufacturing and much of our pollution, but some of it is blowing back across the Pacific to haunt us. Credit: Lin et al.
