New lifecycle analysis of WTW GHG emissions of diesel and gasoline refined in US from Canadian oil sands crude

Green Car Congress

In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oil sands. g CO 2 e/MJ for US conventional crude oil recovery. This range can be compared to ∼4.4

Argonne analysis shows greenhouse gas emissions similar for shale, conventional oil

Green Car Congress

Shale oil production generates greenhouse gas emissions at levels similar to conventional crude oil production, according to a pair of new studies released by the US Department of Energy’s Argonne National Laboratory. These are shale formations with low permeability and must be hydraulically fractured to produce oil and gas.

Latest status report finds California fuel providers continue pacing ahead of requirements of Low Carbon Fuel Standard; sufficient credits to meet full 2013 obligation

Green Car Congress

According to the latest status report on the progress of California’s Low Carbon Fuel Standard (CA-LCFS) ( earlier post ), regulated parties in the LCFS—oil producers, importers and other fuel providers—continued to exceed the required reductions in carbon intensity specified by the standard. for the first two months of 2013.

First status review of California LCFS finds regulated parties exceeding the standard; compliance production cost about 0.1 cents/gallon

Green Car Congress

A status review of California’s Low Carbon Fuel Standard (LCFS) ( earlier post ) for the period of 2011 and the first quarter of 2012 by Dr. Sonia Yeh at the Institute of Transportation Studies, UC Davis and Julie Witcover found that regulated parties in the LCFS—i.e., gCO 2 e/MJ for gasoline. million), for a net surplus of 0.80

Team from GM, Ford, FCA reviews how to calculate engine efficiency benefits of high octane fuels

Green Car Congress

Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value. Most regular-grade gasoline in the US is sold with a minimum octane rating of 87 AKI, corresponding to approximately 91−92 RON. Premium-grade gasoline is listed as 91−93 AKI minimum, corresponding to 96−98 RON. Leone, James E.

California ARB mods to ZEV regulations for IVMs would result in ~1.9% drop in total ZEV/TZEV units 2018-2025; no impact on air quality requirements

Green Car Congress

The ZEV Regulation has been amended multiple times since its inception (most recently in January 2012 and October 2013) to reflect the pace of ZEV development, the emergence of new ZEV and near-ZEV technologies, and the need to provide clarifying language in an increasingly complex regulatory system.
