In order to limit the impacts of climate change on the planet, the IPCC advocates the reduction of green house gas emissions by half. This objective imposes a 75% (factor 4) reduction on developed countries, like France. Can the transport sector meet this objective?Using the TILT model (Transport Issues in the Long-Term) -which takes into account the macroeconomic links existing between economic growth, technology, mobility and emissions- this paper looks into the necessary conditions in order to attain a factor 4. If technological progresses announced by engineers are met, we can get to a factor 2 (50% reduction), the rest of the reductions will have to be attained by changes in behavior and practices. Three scenario families are proposed in order to better illustrate the adjustments.
