CRC ACES Phase 2 report finds emissions from modern heavy-duty diesels well below required levels

Green Car Congress

2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. Emissions of carbon monoxide and hydrocarbons were also significantly below required 2010 levels: 97% and more than 99.9%, respectively. g/hp-hr between 2007 and 2009 to a level less than or equal to 0.20 Source: CRC.

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.

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. Jacobson found that the combination of the two types of soot is the second-leading cause of global warming after carbon dioxide. Black carbon converts sunlight to heat and radiates it back to the air around it.

UNEP Report Calls for More Sophisticated Approach to Developing Biofuels; Limitations of Current LCA Studies

Green Car Congress

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. World ethanol production for transport fuel tripled between 2000 and 2007 from 17 billion to more than 52 billion liters (13.7 This is mainly as a result of carbon releases from the soils and land.

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 2005, Congress enacted the Renewable Fuel Standard as part of the Energy Policy Act (EPAct) and amended it in the 2007 Energy Independence and Security Act (EISA). All volumes, except for volumes of biomass-based diesel, are in gallons of ethanol-equivalent. Economic effects. Barriers and opportunities.
