EIA: US energy-related CO2 emissions down 2.4% in 2011 while GDP rose

Green Car Congress

The US Energy Information Administration (EIA) reported that after an increase in 2010 of 3.3%, energy-related carbon dioxide emissions in the US in 2011 decreased by 2.4% (136 million metric tons), while GDP grew by 1.8%. Energy-related carbon dioxide emissions have declined in the United States in four out of the last six years.

US EIA Reports Record-setting 7% Overall Decline in US Carbon Dioxide Emissions in 2009; Transport Emissions Down 4.1%, Lowest Percentage Reduction of the End-UseSectors

Green Car Congress

Factors contributing to the 7% drop in emissions in 2009. While emissions have declined in three out of the last four years, EIA noted, 2009 was “ exceptional ”. Carbon intensity changes in the electric power and industrial end use sectors. The average decline in energy intensity from 2000 to 2008 was 2.0%. Source: EIA.

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

Green Car Congress

The SMP model calculates 2000?2050 2050 well-to-wheels (WTW) transportation sector CO 2 emissions in 11 world regions for a number of vehicle types. The researchers used a four-step process in their study: Determining the relative change in global, all-sector CO 2 emissions required for CO 2 stabilization at 450 ppm.

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. Several recent highly cited LCAs that have incorporated vehicle efficiency differences between gasoline and ethanol/gasoline blends could potentially be misleading. Click to enlarge.
