CMU county-level study shows plug-ins have larger or smaller lifecycle GHG than gasoline ICE depending on regional factors

Green Car Congress

A US-wide county-level study comparing lifecycle greenhouse gas (GHG) emissions from several light-duty passenger gasoline and plug-in electric vehicles (PEVs) has found that PEVs can have larger or smaller carbon footprints than gasoline vehicles depending on regional factors and the specific vehicle models being compared.

CMU study explores optimizing PHEV design and allocation to minimize life cycle cost, petroleum consumption, and GHG emissions

Green Car Congress

Jeremy Michalek and colleagues found that while a fleet with plug-in hybrid electric vehicles (PHEVs) with universal high electric range (i.e., 87 miles all electric) minimizes petroleum consumption, minimum lifecycle greenhouse gas (GHG) emissions are achieved with a mix of low-range (~25 miles) and mid-range (40-50 miles) PHEVs.

Third Phase of SDGE In-Use Study Shows PHEVs Excel on Fuel Economy and GHG Emissions Reductions Compared to Gasoline ICE and Hybrid-Electric Vehicles

Green Car Congress

One of SDG&E’s converted PHEVs. The third phase of a SDG&E multi-year in-use study on plug-in hybrid electric vehicles showed that plug-in hybrids offer significant improvements in gas mileage and reductions in emissions when compared with standard hybrid-electric and gasoline internal combustion engine (ICE) vehicles.

Lux Research: despite cheap oil, niche plug-in vehicle sales will be resilient; conventional hybrids to be hardest hit

Green Car Congress

In the likely case of only a gradual return to previous higher prices—which Lux calls the “cheap oil” scenario in its analysis—then electric vehicle (EV) sales will dip by 20% for a number of years, while plug-in hybrid (PHEV) sales will dip by about 14% during that same period, the research firm found.

Researchers suggest subsidies and policies targeting plug-ins with small battery packs would produce more benefits at lower cost

Green Car Congress

Their paper, to be published in the summer issue of the journal Issues in Science and Technology , is based on their earlier study that found that strategies to promote adoption of hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) with small battery packs offer more social benefits (i.e., Earlier post.).
