The aim of the PROLIBIC project is to bring together acquired knowledge from 4 projects carried out within the research programme SSD: PROMOCO (Professional mobility and company car ownership), LIMOBEL (Long-run impacts of policy packages on mobility in Belgium), BIOSES (Biofuels Sustainable End uSe) and CLEVER (Clean Vehicle Research: Life Cycle Analysis and Policy Measures). It concerns results on both transport activities and environmental impact. The second focus of the project consists of defining two scenarios, for which model runs are also performed with the LIMOBEL models. Furthermore, we aspire to disseminate the results acquired within PROLIBIC and the 4 underlying projects with policymakers at both the national and regional level.
