Vehicle lifetime in different mobility solutions

Research Project, 2020 – 2021

The transport system is currently undergoing several changes that will play a critical role for the sectors pathway towards zero CO2 emissions. (1) Electrified vehicles are increasing its share of new sales, (2) car sharing is on the rise, and (3) connected and autonomous vehicles (CAVs) are coming. Studies have pointed out that one shared CAV may replace several (in the order of 10) conventional individually owned vehicles. This causes the vehicles to be used much more intensively compared to today. The lifetime aspect become especially important if battery electric vehicles will take a larger share of the market, since the production phase of the cradle-to-grave energy needs for battery electric vehicles (BEV) is
much larger than for internal combustion engine (ICE) vehicles. The overall aim is to analyze and improve the knowledge on how cradle-to-grave energy requirements and CO 2 emissions for different transport system solutions (shared vs individual mobility) depend on the car lifetime and the constraining lifetime factors (calendar age vs cumulative mileage).
