Transportation accounts for about one-third of our greenhouse gas emissions. For the Department of Loire-Atlantique, acting on modes of travel represents an important lever to reduce these emissions and move towards the decarbonation of mobility.

This is why the Department continues to deploy carpool areas on the territory, with the desire to deploy electric charging stations. He is also working on the upcoming development of dedicated transit and carpool lanes. This project will make a real difference in journey times, making shared transport more attractive for road users.
