CARBON-DIOXIDE EMISSIONS FROM TRANSPORT IN IEA COUNTRIES: RECENT LESSONS AND LONG-TERM CHALLENGES

This report summarises three years of research carried out at Lawrence Berkeley National Laboratory from 1993 to 1995, and subsequently updated at the International Energy Agency. The bases for the work are threefold: First, a new international database of transportation activity and fuel use in industrialised countries, at national and local levels; second, a series of statistical analyses of key trends in transportation, energy use and consequent carbon emissions; and third, a brief review of policies to restrain carbon emissions from transportation. At the centre of much of the analysis is new framework, "ASIF", for decomposing changes in carbon emissions into changes in transportation activity, modal shares, modal energy intensities, and carbon content of fuels. These results are compared with present or proposed policies to see if policies are likely to weaken the components of rising emissions. (A)
