Researchers suggest that air quality tests need simplifying to help reduce dangerous emissions

Green Car Congress

New methods of testing and simulating air quality should be considered in order to help policy makers have a more accurate understanding of how emissions affect air pollution levels, new research suggests. We consider this to be a “bottom-up” approach,” says Stockwell. Stockwell, Emily Saunders, Wendy S. Goliff & Rosa M.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

In general, biofuels made from organic waste are environmentally more benign than those from energy crops. Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions).
