Humankind has great responsibility on environment. The most valuable heritage to the next generation is leaving them a clean, green and liveable world. In the last century, environment has used loutishly and unconsciously. People’s indifference and irresponsibility to the environment make it dirty and natural sources have been decreasing day by day. Among many environmental problems, the most serious and threatening our future are; environmental and air pollution, depletion of natural resources, and lack of recycle and reuse. European Commission’s 7th Action Programme to 2020 published in March 2015 emphasises clean air and water, recycle, reuse and sustainability of resource efficiency. To decrease and solve these problems and had more responsible individuals, promoting environmental awareness at school years was an effective way to create environmentally-conscious citizens.Our project aim was to raise interest on environmental problems among students, teachers and parents with the activities in and out of the school and other people with transnational meeting activities. We had three main steps: First, We attracted our students’ attention on environmental issues. Environmental issues and project activities were included in the curriculum and monthly implementation activities at schools. Second, we did various activities for better environment such as planting trees, workshops, organizing open to public activities such as Walk, Critical Mass, and celebration international days, competitions shooting film, documentary or public service ads to raise awareness on environmental problems. In the last step, we enhanced our students and the community’s ability to act responsibly for a sustainable future. For this step, we prepared leaflets, infographics, public interviews and polls, and organized contests by integrating many people from all age and profession group.Additional to these; we did extra cultural activities to learn more about our partners and overcome the prejudices, raise cross-cultural awareness and sensitivity among students. Active study language was English in this project. All developed materials were translated into English and students had the opportunity to improve their English. Students were actively involve in all project activities. They planned and implemented the activities and teachers were their guide. Students worked cooperatively during learning/teaching/training activities for workshops, social responsibility activities and creating project forests, and teachers discussed, evaluated, and planned project activities and road map.All activities and products created during this project were published on school Project Corner Walls, Project websites, Project Facebook Page, School magazines, leaflets, local newspapers, and local TV channels. We had concrete products such as 9 memorial mini forests, toys, objects, and souvenirs made by waste materials, brochures, posters, films or documentaries and recycle bins for dissemination of our projectAt the end of this project, especially students and then local people were aware of the problems of environment they were more environment-friendly individuals. With the activities and public service ads local people also realized the environmental degradation, problems and solutions. In medium term programme, the significant problems of partner cities/towns (pollution, deforestation, recycle, reuse) were decreased. In long term, partner countries had memorial forests and greener and cleaner environment, responsible individuals, a good friendship and work together for further partnerships.
