Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

Full-fuel-cycle GHG emissions estimates for reformulated gasoline pathways by LCA study. He found that the variation in oil sands GHG estimates is due to a variety of causes. These include oil sands, enhanced oil recovery, coal-to-liquids and gas-to-liquids synthetic fuels, and oil shale.

National Low Carbon Fuel Standard study releases major Technical Analysis and Policy Design reports; providing a scientific basis for policy decisions

Green Car Congress

Very broadly, they found that an LCFS would buffer the economy against global oil price spikes, trim demand for petroleum, and lessen upward pressure on gas prices. Set a target of reducing the carbon intensity of gasoline and diesel by 10 to 15 percent by 2030. Create separate fuel pools for gasoline and diesel.

National Academies Report Examines Hidden Cost of Energy Production and Use in US; Estimates $120B in 2005

Green Car Congress

A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.

Road Test: 2024 Lincoln Corsair PHEV Grand Touring III

Clean Fleet Report

The Corsair was first only available with a gasoline engine, but in 2022 the efficient plug-in-hybrid (PHEV) was introduced. The perfect bridge between a gasoline-propelled vehicle and one that runs purely on batteries is making more sense to people. There is a sixth mode of Preserve, which saves the battery charge for later use.
