The overall goal of Green Generation was to raise ecological awareness among youth while fostering the 8 key competences for lifelong learning. The exchange brought together 40 young people and youth leaders from Lithuania, Estonia, Italy, Turkey, and Romania. We wanted to empower those youths in becoming informed, active, and responsible citizens, capable of addressing modern environmental challenges and inspiring others toward sustainable lifestyles, promoting also cooperation across cultures and encouraging participants to act locally with a European perspective on sustainability. To achieve this we used a mix of non-formal education methods, intercultural dialogue, and practical ecological actions, with the goal of increasing participants’ awareness of environmental issues, understand impact of human activities and equipping them with tools and good practice to make tangible, positive changes in their communities. The project’s measurable objectives were: At least 30 participants improved their ability to identify and propose solutions to environmental challenges (measured through pre- and post-project questionnaires). Two local follow-up actions organised by each National team to promote environmental protection and sustainability. The Co-creation of a 20-page “Sustainable Living Guide”, covering different ecological topic, sharing knowledge and good practices learned during the exchange. At least 75% of participants to report a stronger sense of connection with nature and motivation to adopt more sustainable life style after the project. In addition, we also wanted to: Increase environmental knowledge and critical thinking skills — enabling participants to understand the impact of human actions on the eco-system and identify, analyse, and propose solutions to environmental problems in their daily lives and communities, Promote sustainable practices — guiding young people to adopt more eco-friendly behaviours and reduce their environmental footprint through mindful consumption, waste reduction, and responsible resource use. Foster active citizenship and community involvement — inspiring participants to engage in environmental actions at the local level and to influence others to care about sustainability. Encourage intercultural cooperation and mutual learning — providing a space where participants from different cultural backgrounds could exchange good practices and ideas for protecting the environment. Develop communication and leadership competences — supporting young people in expressing environmental concerns clearly and confidently, using creative formats such as workshops, videos, and the “GreenGen Guide” produced during the exchange. By the end of the project, most participants reported a better understanding of ecological principles and felt more capable of contributing to environmental protection.
