The project YOUTH ALPINE EXPRESS is a project for strengthening youth participation in the Alps regarding the topic of sustainable mobility and new consumer behavior through the development of a new learning tool: an experiential journey through sustainability in the Alps. Target groups are young people, youth workers and decision-makers from several Municipalities from all over the Alps. Around 20 young people from 4 alpine countries (France, Italy, Slovenia and Austria) accompanied by 4 youth workers are participating. They are travelling from their hometown to two alpine relevant events only by sustainable transport means. They have a given time and a given CO2 Budget to respect. The travel is as team-game conceived, so the CO2 Budget is valid for the all group for 5 days. It means the singles or some small groups will have to bargain with each-other to stick to the given rules. During this travel the participants are meeting some decision-makers, presenting their experience in the public and recording their choices in a CO2 Documentation, where it will be visible also the added value of each decision (travelling by feet was taking longer but I enjoyed the landscape, I got a new friend and so on….)A coach will support the young participants before the journey, in the planning phase and in producing creative formats (postcards, flash mobs) to present the thematic challenges to a broader public during the event thy are joining.A website will report about the journeys, collect the CO2 documentation as well as multimedia-reports, dialogue with decision-makers and stay as a new tool to travel in a sustainable way through the AlpsAims of the project are:- young people living in the Alps is aware that traveling in a sustainable way has an high added value and is an important contribute to reach the aim carbon-neutral Alps.- decision-makers make possible more youth participation regarding mobility policies- Youth workers increase their know-how regarding the topic of sustainable mobility and 2000-Watt society and are able to inform and sensitize a broader group of young people.
