Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

Green Car Congress

However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. An open-access paper on their work is published in Nature Communications.

Ninth annual Green Innovation Index finds California light-duty vehicle emissions spike; major challenge to 2030 climate goals

Green Car Congress

However, although the state has made considerable progress decoupling economic growth from greenhouse gas (GHG) emissions, the rate of emissions decline appears to be slowing, due in part to a spike in transportation emissions attributed to an increase from light-duty vehicles. But the effects of these efforts seem to be reaching a plateau.

Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Now, a study by researchers at the US Department of Energy (DOE) Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has found that energy sorghum ( Sorghum bicolor ) behaves more like miscanthus in the way it efficiently captures light and uses water to produce abundant biomass.
