In their efforts to reach climate objectives in matters of daily mobility, cities face several challenges linked to citizens’ refusal and reticence to change their mobility modes. This is an important issue as it is linked to path dependency and the car culture: logistics, infrastructures, politics, economics, attitudes, behaviors, time and activities. The empirical study – a survey undertaken with 650 Lyon citizens – aimed at understanding the motivations and reasons for their relative rejection of climate friendly modes of transports. The analysis shows that climate change is not a factor playing a role in daily mobility decisions, even for citizens who consider that CC is the 21st century’s number one issue.
