For example why not try sustainable mobility? Less polluting and often more humane and physical, there are a number of options in Luxembourg.
In Luxembourg, thanks to the company Vél’oh, bikes are available 24/7 on a self-service basis for those short journeys. There are vél’oh stations all over the place, near shops, popular places and public transport. There are various subscription possibilities, which means you can use the Vél’oh service for a whole year or just a day. In a similar vein the association « Vélo en ville » allows you to rent bikes and gear for the whole family.
With car sharing you can get to work without taking the train or paying a fortune for petrol. The concept? Share the journey and it’s costs with other people. Not only do you reduce your carbon footprint but also you reduce your petrol and parking costs. To test this means of transport there are a number of websites, you just need to check if there are journeys scheduled which meet your requirements.
