decline in energy-related CO2, according to the latest report from the US Energy Information Administration (EIA). Emissions have declined in 6 out of the past 10 years, and energy‐related CO 2 emissions in 2016 were 823 MMmt (14%) below 2005 levels, according to the EIA. Transportation increase led by gasoline consumption.

EIA: US energy-related CO2 dropped 2.7% in 2015; of end-use sectors, only transportation increased

Green Car Congress

Energy-related CO 2 emissions in 2015 were about 12% below 2005 levels. Specific circumstances, such as the very warm fourth quarter of 2015 and relatively low natural gas prices, put downward pressure on emissions as natural gas was substituted for coal in electricity generation.

EPA trends report sees record levels of average new vehicle fuel economy and CO2 emissions for MY 2012; role of new gasoline vehicle technologies

Green Car Congress

EPA projects advanced transmissions (6+ speeds and CVTs), gasoline direct injection (GDI) systems, and turbocharged engines will be installed on at least 15% of all MY 2013 vehicles. The majority of the emissions and fuel savings from current vehicles, EPA noted, is due to new gasoline vehicle technologies. Click to enlarge.

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

Green Car Congress

The Ford team updated the SMP model with historical data for 2000, 2005, and 2010, and extended the model to calculate the total CO 2 emissions (tonnes) and the TTW (tank-to-wheel) emission rate (g CO 2 /km) for the new vehicle fleet. Biofuel plays a large role in North America, enabling the relaxation of the near-term (2015?2025)
