UC Davis Study Finds That Near-Term Marginal Electricity Mix in California for Plug-in and Fuel Cell Vehicles Will Result in Fuel With Carbon Levels More Than 60% Higher Than Estimated in the LCFS

Green Car Congress

The marginal electricity emissions rate will be higher than the average rate from all generation—likely to exceed 600 gCO 2 equiv.kWh -1 during most hours of the day and months of the year—and will likely be more than 60% higher than the value estimated in the Low Carbon Fuel Standard.

California ARB considering four new low-carbon fuel pathways; Neste renewable diesel and sugarcane molasses ethanol

Green Car Congress

Others are sugarcane molasses ethanol from Guatemala; mixed feedstock to biodiesel from Texas; and a new ARB-staff-developed pathway for North American landfill gas. The CI of a fuel is determined by the sum of all greenhouse gas emissions associated with the production, transportation, processing and consumption of a fuel (its pathway).

Two Studies on Regional Options for Reducing GHG Highlight Need for Reduction in Travel Intensity

Green Car Congress

2009) Click to enlarge. Achieving targeted regional reduction in greenhouse gas (GHG) emissions from the transportation sector will require concentrated efforts to change travel behavior and reduce vehicle miles travelled in addition to advances in vehicle technology and fuels, according to two recent studies.

UN report finds world needs incremental $1.9 trillion invested in green technologies to avert planetary catastrophe; global per capita cap on primary energy consumption of 70 GJ/yr may be required

Green Car Congress

The past decade was the first in two centuries with increasing CO2 emissions intensities, owing to a “coal revival”, in contrast with the rapid conversion to natural gas in the 1990s. These trends, which are diametrically opposed to declared greenhouse gas mitigation goals and targets, are by no means limited to emerging economies.
