Policy packages for modal shift and CO 2 reduction in Lille, France

•This paper proposes policy scenarios to cut CO2 emissions caused by urban mobility.•After representing mode choice on the territory and simulating the effects on CO2 emissions of different suggested scenarios, we find that: an increase of 50% in parking charges combined with a cordon toll of €1.20 and a 10% improvement in travel time by public transport (based on the revenue from tolls) is the winning scenario.•Combining the tools always reduces more CO2 emissions via modal shift than implementing them separately.
