Average Carbon Intensity of crude to California refineries in 2012 down very slightly from 2010 baseline

Green Car Congress

Staff of the California Air Resources Board (ARB) has posted its calculation of the average 2012 annual carbon intensity of crudes supplied to California refineries. gCO 2/MJ, calculated by weighting the carbon intensity value for each crude by the volume supplied to California refineries during 2012.

Final EPA report shows total US GHG emissions up 3.2% in 2010, total CO2 up 3.5%, total transportation CO2 up 1%

Green Car Congress

The final report shows overall emissions in 2010 increased by 3.2% EPA attributes the trend to an increase in energy consumption across all economic sectors, due to increasing energy demand associated with an expanding economy, and increased demand for electricity for air conditioning due to warmer summer weather during 2010.

Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

The Ford team updated the SMP model with historical data for 2000, 2005, and 2010, and extended the model to calculate the total CO 2 emissions (tonnes) and the TTW (tank-to-wheel) emission rate (g CO 2 /km) for the new vehicle fleet. To achieve 450 ppm, WTW LDV CO 2 emissions decrease 25% from 2000 and 34% between 2010 and 2050.

California ARB staff considering including alternative jet fuel in Low Carbon Fuel Standard

Green Car Congress

The staff of the California Air Resources Board (ARB) staff is considering including alternative jet fuel (AJF) in the Low Carbon Fuel Standard (LCFS). In 2009, the ARB approved the LCFS regulation to reduce the carbon intensity (CI) of transportation fuel used in California by at least 10% by 2020 from a 2010 baseline.

ExxonMobil predicts peak in light-duty vehicle liquid fuels ~2030, but ongoing role for oil in the mix

Green Car Congress

While the mix shifts toward lower-carbon-intensive fuels, the world will need to pursue all economic energy sources, the report says. At the same time, total miles traveled per year by cars, sport utility vehicles (SUVs) and light trucks will increase about 60%, reaching about 14 trillion in 2040. l/100 km) in 2040.
