Taking another look at methanol as an alternative transportation fuel for the US

Green Car Congress

A recent white paper by Leslie Bromberg of MIT’s Plasma Science and Fusion Center and Wai K. It is a high octane fuel with combustion characteristics that allow engines specifically designed for methanol fuel to match the best efficiencies of diesels while meeting current pollutant emission regulations. It is a safe fuel.

Study finds GHG emissions associated with palm oil production have been significantly underestimated; implications for carbon intensity of biofuels as well as biofuel policies in Europe

Green Car Congress

The study led by a team from the University of Leicester (UK) suggested that 86 Mg CO 2 -eq ha -1 yr -1 (over 50 years) or 100 Mg CO 2 -eq ha -1 yr -1 (over 25 years) represent the best available estimates of typical emissions from peat decomposition in palm plantations.
