CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). The study used two fuels—an E10 and E15. SULEV30, ULEV50, ULEV70, and ULEV125).

BP Energy Outlook 2030 sees emerging economies leading energy growth to 2030; global CO2 emissions from energy well above IEA 450 scenario

Green Car Congress

In both the base-case and a scenario with more aggressive environmental policies, CO 2 emissions from energy use remain well above the IEA 450 scenario. However, both cases result in global CO 2 emissions well above the IEA 450 scenario—a back-cast which illustrates what is required to stabilize greenhouse gas concentrations at 450 ppm.
