Level of activity or vehicle use is an important factor totake into account in the overall analysis of transportation emissions, particularly in those caseswhere long-run solutions are envisioned to help avoid the development of a problem. In anumber of developed countries (where data and information are more readily available), studieshave shown that growth in activity has either significantly increased the amount of CO2 emittedin the sector or substantially dampened the reduction of CO2 emissions that would have occurred,the latter because of efficiency improvements during the last three decades of the twentiethcentury. In the absence of a policy to address vehicle use, growth in vehicle kilometres travelledin developing countries is projected to average between 2.5 and 4 per cent per year between 1990and 2030.
