Researchers map CO2 emissions for entire Los Angeles Megacity to help improve environmental policymaking

Green Car Congress

For example, about 60 percent of roadway emissions come from 10 percent of the roads. We can identify the ones with the highest emissions and track how well efforts to reduce those emissions are working. Other cities Gurney has mapped to this degree are Indianapolis, Salt Lake City and Baltimore. million people.

Study finds GHG methane offsets its warming ~30% and precipitation increase ~60% by short-wave absorption

Green Car Congress

A new study by researchers from the University of California, Riverside and colleagues in the US and Europe has now found that methane short-wave absorption counteracts ~30% of the surface warming associated with its long-wave radiative effects. However, greenhouse gases also absorb short-wave radiation incoming from the sun. Randles, C.A.

Researchers find bio-inspired high-tech surfaces on hulls could greatly reduce drag and CO2 emissions of ships; up to 1% of global CO2

Green Car Congress

If ship hulls were coated with special bo-inspired high-tech air trapping materials, up to 1% of global CO 2 emissions could be avoided according to a new study by researchers from the University of Bonn together with colleagues from St. This corresponds to almost one percent of global CO 2 emissions.

UB study finds link between ambient ozone exposure, artery wall thickness

Green Car Congress

Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. The longitudinal study followed nearly 7,000 people aged 45 to 84 from six US regions: Winston-Salem, North Carolina; New York City; Baltimore; St.
