When it comes to energy security and climate change concerns, transportation is the principal culprit. It consumes half the oil used in the world and accounts for almost one-fourth of all greenhouse gas (GHG) emissions. In the United States, it plays an even larger role, consuming two-thirds of...

The method of force field analysis is used to examine the future technological and market evolution of electric two-wheelers (E2W) in China. The authors identify key forces driving and resisting future E2W market growth, root causes behind these forces, and important insights about the...

This report documents the automotive industry's response to federal regulations of light duty vehicle tailpipe emissions, with the intent of identifying lessons learned that might be applicable to future regulation of greenhouse gas emissions. The focus is on 1975 and 1979-1981, when new...

Diesel vehicle sales in the European Union have increased from 23% of all light duty vehicles sold in 1994 to 41% in 2002. This rapid increase in market penetration is due to four related factors: a voluntary agreement by European automobile manufacturers in 1998 to reduce CO2 emissions from new...

My friends and colleagues, I would like to talk to you today about two big problems....

Executive Order S-1-07, the Low Carbon Fuel Standard (LCFS) (January 18, 2007), calls for a reduction of at least 10 percent in the carbon intensity of California’s transportation fuels by 2020. It instructed the Secretary of the California Environmental Protection Agency to coordinate...

Mel Webber wrote and thought a lot about cars. He frequently pointed out that cars remain the first choice for transport for most people because their convenience and door-to-door accessibility are unmatched by any other mode. However, many cities are headed toward traffic paralysis because cars...

Local governments can have a large effect on carbon emissions through land use zoning, building codes, transport infrastructure investments, and support for transportation alternatives. Recognizing this, many cities have developed climate action plans, containing a disparate mix of mostly...

In November 1997, the California Air Resources Board proposed modifying the Zero Emission Vehicle (ZEV) mandate such that certain vehicles with measurable tailpipe emissions would be allowed to earn partial credit toward the 10% requirement of 2003. This proposed change in the ZEV mandate would...
