We are nowadays consuming more resources than the planet can restore every year. Climate change and resource consumption are strongly impacting our lives, and this could lead in the near future to the destruction of our ecosystem. With the implementation of this Erasmus+ project “Circular Economy for Youth: CEFY ”, we wanted to equip 30 youth workers (our participants) with skills in the sectors of green economy and circular economy in order to increase their ability to develop actions and activities on the theme of ecology for the youngsters of their communities, to promote environmental awareness, and to mitigate the effects of resource wasting and climate change. We also wanted to equip them with YouthPass-linked competencies to solve waste issues in their local areas of partner organizations countries. This aspect was aligned with the European Union Green Deal Agenda by 2050 "Circular Economy Action Plan" and Erasmus+ 2021-2027 objectives: combating climate change. It was also for all of us youthworkers to find new ways to promote circular economy among the youngsters we work with. Through this Training Course (TC), we wanted to teach youth workers nonformally how to start thinking in more sustainable ways, even from an entrepreneur's point of view. The project CEFY—Circular Economy For Youth had the goal of equipping a group of 30 Youth Workers and 2 trainers with knowledge, tools, and skills Through this TC, participants will learn what a circular economy is and will acquire the abilities to inform youngsters on this theme, promoting daily actions to reduce garbage and to develop a more sustainable way of life. Our main goal was to make young participants in the project aware of the principles of circular economy through the sharing of tools, innovative evidence-based knowledge, and competences that could help them promote circular economy in their local areas as well as with the young people they work with. The main objectives of the projects were: - To increase the knowledge of circular economy among the participants of the project - To promote a more sustainable approach among young people who will participate in the project - To increase the skills and abilities of young people on the principles of circular economy - To raise awareness about the advantages of using circular economy in our daily lives - To increase the abilities of YouthWork on how to develop events and local campaigns on sustainability and circular economy.
