YOIS is an independent youth movement that unites young people who want to build a better future for today’s youth and future generations. It offers young people a chance to discuss issues of importance and then influence and lobby political decision-makers. Its goal is a sustainable and intergenerationally-just society. Sustainability will be achieved as soon as no generation lives at the expenses of the following ones. An intergenerationally-just society will be attained when each generation has got the possibilities to develop as far as the previous one. Other ideas of justice like e.g. social justice or gender justice are not left aside but they do not belong to the actual area YOIS concentrates its activities on in order to reach its aims.
