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

Green Car Congress

These factors included a decline in the carbon intensity of the energy supply (CO 2 /British thermal units [Btu]) of 1.8%; and a 3.4% 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.

Annual Increase in Global CO2 Emissions Halved in 2008; Decrease in Fossil Oil Consumption, Increase in Renewables Share

Green Car Congress

In addition to high oil prices and the financial crisis, the increased use of new renewable energy sources, such as biofuels for road transport and wind energy for electricity generation, had a noticeable and mitigating impact on CO 2 emissions. Global CO2 emissions increased from 15.3 Click to enlarge. billion tonnes in 1970, to 22.5

GM Quantifies CO2 and Fuel Consumption Reductions Via E-REVs And PHEVs, As Compared To Conventional Hybrids

Green Car Congress

General Motors has released a white paper that evaluates the CO 2 reduction potential of extended-range electric vehicles (E-REVs) as well as plug-in hybrids (PHEVs), in combination with multiple vehicle charging scenarios, as compared to conventional hybrids. The vehicles are defined as follows: Hybrid Electric Vehicle (HEV) : A 2.4L

Study finds removing corn residue for biofuel production can decrease soil organic carbon and increase CO2 emissions; may miss mandated 60% GHG reduction

Green Car Congress

Using corn crop residue to make ethanol and other biofuels reduces soil carbon and under some conditions can generate more greenhouse gases than gasoline, according to a major, multi-year study by a University of Nebraska-Lincoln team of researchers published in the journal Nature Climate Change.
