A recent Eurobarometer survey, which was carried out by the European Commission, shows the growing concern of European citizens regarding climate change: 79% of European citizens think it is a very serious problem. In 2016 the temperature of the planet had risen 1.1º C in relation to the end of the 19th century, and more and more studies support the thesis that global warming and climate change can generate enormous damages and impacts in the economic, social, environmental and human health fields, as supported by the European Environment Agency. For all this, the key to being able to fight against climate change effectively is to achieve sustainable development that, at the local level, translates into the assimilation of sustainability within the lifestyle of people, entities, companies and administration. And to achieve this sustainable development, it is necessary to empower and provide knowledge about the young population, which is the present and the future of Europe. The ALAS project (It's All About Sustainability) is a mobility project for youth and youth workers, whose main goal is to empower youth and raise awareness in terms of sustainability, to result in a change in their habits, especially within its entities, and a promotion of entrepreneurship under the prism of respect for the environment. From the ALAS project, it is proposed that this search for sustainability be carried out from personal experiences within associations or entities, encouraging analysis of its reality with the aim of improving it. The search for solutions and, during this, the learning and awareness of environmental problems, will empower young people and include that vision in a lasting way so that new opportunities are opened for them to undertake their own projects. The objectives set to achieve the project goal are the following: -To create a network of the long-term collaboration between international youth organizations in the field of sustainability. -To develop skills in young people in terms of sustainability and entrepreneurship, and provide them with resources to help them succeed in the field of entrepreneurship. -To generate awareness and knowledge of the environmental reality, through the concept of sustainability and the analysis of the near reality of young people. -To use non-formal education methods to develop entrepreneurship skills under the premium of sustainability and respect for the environment. -To facilitate new opportunities for young people at risk of exclusion or with fewer resources through their empowerment and tools in entrepreneurship and sustainability. -To promote international cooperation in the field of sustainability and entrepreneurship.
