Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states).

Up close and personal with Volkswagen’s e-Golf carbon offset project: Garcia River Forest

Green Car Congress

In 2014, Volkswagen of America announced that starting with the launch of the zero-tailpipe emissions battery-electric 2015 e-Golf ( earlier post ), it would invest in projects to offset the carbon emissions created from the e-Golf on a full lifecycle basis: production, distribution and up to approximately 36,000 miles (57,936 km) of driving.

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

Green Car Congress

while the carbon intensity of its economy declined by 4.5%. Changes in emissions by Scoping Plan sector between 2000 and 2017. Emissions from gasoline used in on-road vehicles are the main driver of that increase. These reductions have occurred while California’s economy has continued to grow.

Tohoku team finds swirling ammonia in combustion chambers can help reduce NO emissions

Green Car Congress

The finding helps advance research into ammonia as an alternative to carbon-based fuels for cars, airplanes, and power generation facilities. Nitric oxide is known to be harmful to human health, contributes to ozone depletion, and when it reacts with other compounds, contributes to acid rain and atmospheric warming.

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

Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming. However, climate models to date have mischaracterized the effects of soot in the atmosphere, according to Jacobson, director of Stanford’s Atmosphere/Energy Program. Jacobson at Stanford University.

ARB releases proposed cap-and-trade regulation for comment; transportation fuels impacted in 2015

Green Car Congress

The cap is enforced by requiring each source that operates under the cap to turn in one allowance or offset credit for every metric ton of carbon dioxide equivalent (MTCO 2 e) that it emits. Tags: Climate Change Emissions Fuels Policy. Over time, the cap will steadily decline. Offset Protocols. Cap and Trade 2010.
