The California Zero Emission Vehicle (ZEV) rule, adopted in 1990, is arguably one of the most daring and controversial air quality policies ever adopted. Some consider it a policy failure, while others credit it with launching a revolution in clean automotive technology. This paper is the first...

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...

Presented at the National Hydrogen Association Annual Hydrogen Conference (NHA 2005), Washington, DC, March 29 - April 1, 2005 The first step, in any program of self-improvement, is admitting you have a problem. My friends and colleagues, I would like to talk to you today about two big problems....

Beijing could be an attractive region to initiate a hydrogen infrastructure for transportation. Air quality is poor, oil imports are soaring, and there is a desire to introduce innovative responses for the 2008 Olympics. If Beijing were to proceed to build hydrogen infrastructure before and...

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...

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...
