The main objective of the youth exchange "The BigFoot footprint: Our Environmental Footprint!" is gaining knowledge about reducing our environmental footprint. The second objective of the exchange is to develop the soft skills of the participants, more specifically their cultural awareness, teamwork ability, English language skills and leadership abilities. In addition to the development of the above-mentioned, the main final product of the exchange is the creation of an informational video that will inform the society about the environmental footprint problem and will be published after the implementation of the exchange. The inevitable climate change, the spread of the environmental problem, its degradation and exploitation, are among the biggest problems we face as humanity today. Efforts to mitigate environmental impacts, such as the European Green Deal or the 2015 Paris Agreement, are important, but our fellow citizens still do not want or know how to reduce their environmental footprint. Despite the slowly growing awareness of the inevitable negative impacts of climate change, such as the greenhouse effect, rising sea levels and loss of biodiversity, the footprint associated with individual lifestyles is still unknown to the majority of society. Despite the EU's commitments and efforts, the majority of people in the European Union are still unaware of the environmental impact of their daily lives. Therefore, learning about the environmental impact we leave behind in our daily activities could serve as a good start to increase social responsibility among young citizens. Unfortunately, we will never be able to turn back the times and make humanity environmentally responsible before the looming threat of climate change, but we can still change many aspects of our lives and slow down the effects of climate change. Now is the time to act. And most importantly - everyone together. The youth exchange "The BigFoot footprint: Our Environmental Footprint!" is closely linked to the objectives of the Erasmus + program as it supports young people of various nationalities to implement a program based on the principles of non-formal education, in Greece. The exchange methodology will promote the active participation of young people, as well as cooperation, the quality of learning outcomes, inclusion, creativity. Also the exchange promotes innovation and exchange of good practices at the level of organizations and policies in the field of youth. Emphasis is placed throughout our program on inclusion and sustainability which are both key priorities of our exchange. In addition, the exchange fulfills the ERASMUS + priorities, in particular the participation of young people with fewer opportunities, the sustainable development of Europe, and the improvement of the digital competences of the participants.
