Study projects emission impacts of inexpensive, efficient EVs: 36% further reduction in LDV GHG by 2050, or 9% economy-wide

Green Car Congress

A new study by researchers at the University of Colorado at Boulder projects the emission impacts of the widespread introduction of inexpensive and efficient electric vehicles into the US light duty vehicle (LDV) sector. The database includes joint Corporate Average Fuel Economy (CAFE) and GHG emission standards for LDVs.

U Toronto LCA suggests that with CNG as primary vehicle energy source, EVs best targeted at non-attainment areas

Green Car Congress

This distinction can have important policy implications for regions that rely on non-petroleum sources of electricity, which is increasingly natural gas in much of the US. They then estimated the NPVs of climate change and human health impacts from the GHG and CAC emissions, respectively.

CMU study finds small battery PHEVs and gasoline hybrids the least-cost policy solution to reducing gasoline consumption

Green Car Congress

The federal subsidy significantly favors larger battery packs to a stronger degree than their potential for additional gasoline savings. air emissions and oil displacement benefits) in the near term per dollar spent than PHEVs and battery-electric vehicles (BEVs) with large battery packs providing longer electric range.

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. Earlier post.)

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

Green Car Congress

The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand. The researchers also considered intermediate (20% electric-powered miles) electrification—halfway between the high and low.

UC report to CalEPA outlines policy options to decarbonize California transportation by 2045

Green Car Congress

A team of transportation and policy experts from the University of California released a report to the California Environmental Protection Agency (CalEPA) outlining policy options to significantly reduce transportation-related fossil fuel demand and emissions. A second study led by UC Santa Barbara was released simultaneously.

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University.
