This report was undertaken for the PEW Center on Global Climate Change and deals specifically with the issue of Greenhouse Gas Emissions from the Transport Sector in South Africa. As a country study its focus is on the national level due to the relative size of the transport sector in South...

Truck manufacturers and vehicle component manufacturer are exploring using fuel cell auxiliary units (APUs) in lieu of main engine idling. While fuel cell powertrains continue to face significant technical and economic barriers, the truck auxiliary power application may offer a viable near-term...

To more accurately predict hourly running stabilized link volumes for emissions modeling, a new method was recently developed that disaggregates the period-based model link volumes into hourly volumes using observed traffic count data and multivariate multiple regression (MMR). This paper...

The impacts of home-based telecommuting on travel behavior and personal vehicle emissions for participants in the State of California Telecommuting Pilot Project are analyzed using the most advanced emissions modeling tools currently available. A comparison of participants' telecommuting day...

The use of energy accounts for a major fraction of all anthropogenic emissions of greenhouse gases (IPCC, 1995) , and in most industrialized countries the use of transportation fuels and electricity accounts for a major fraction of all energy-related emissions. In the transportation sector...

The secondary benefits of the ZEV Program have been discussed in this report in terms of nine categories – (1) patents, (2) government/industry consortia, (3) new economic activity in California, (4) advanced vehicle development, (5) vehicle emissions outside California, (6) low-speed...
