California 2017 GHG inventory shows 1.2% total drop from 2016; transportation sector emissions up 1%

Green Car Congress

Transportation sector emission sources include combustion of fuels utilized in-state that are used by on-road and off-road vehicles, aviation, rail, and water-borne vehicles, as well as a few other smaller sources. This is, however, the lowest growth rate over the past 4 years. The inner ring shows the broad Scoping Plan sectors. Source: ARB.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The growth in hydrous ethanol, which uses a blend of 94-95% ethanol to 5-6% water, rapidly increased during the 1980s, with consumption peaking in 1989. water content in it and Gasoline C, or E25, which is a mixture of 75% Gasoline A and 25% in volume of anhydrous ethanol (AEAC) with a maximum of 0.4% 40 CFR § 80.27 40 CFR § 80.27(d)

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Green Car Congress

In the absence of major technological innovations or policy changes, the United States is unlikely to meet cellulosic biofuel mandates under the current Renewable Fuel Standard (RFS2) by 2022, according to a new report from the National Research Council. Economic effects.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Soot could be further reduced by converting vehicles to run on renewable electric power. Warming of the air by any chemical, including soot, enhances natural surface emissions of water vapor [e.g., 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b].

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

Other observations included: Most studies only include energy consumption (sometimes only non-renewable energy, sometimes total energy) and CO 2 emissions. A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials.

Damages are expressed in cents per VMT (2007 USD). The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation.
