The concept of sustainability was first mentioned at the World Environmental Conference,held in Stockholm in 1972.However,in Brundtland Report published by the UN Comission on Environment and Development in 1987, it was also defined as the concept of sustainable development and today its scope has been expanded thoroughly.The concept of sustainability is based on the idea of reducing environmental problems as well as preserving the natural structure of the environment. Along with the needs of the next generations, the aim of bringing the idea of long-term sustainable consumption to daily life without putting the whole World in danger reveals the importance of this concept. Protecting the environment will only be possible if individuals have the confidence to act with an edequate environmental awareness.In this context,school as educational istitutions should strictly follow the principles of sustainable development as a whole,including their students, teachers,administrators,assistant staff and families.The ESST Project aims to contribute to their target audience, who develop empathy for all lifestyles , adopt sustainability as a life principle , can look at nature as a whole and be aware of the effects of their beavior on nature.In addition,it will contribute to the development of basic skills and competences (Science and Social Science , Language,ICT, etc.) by supporting its partivipants a academically.By including disadvantaged student groups in the Project , they will increase their loyalty to school,remove social barriers and work specifically to raise therir academic success.In addition , it will enable the exchange of good practices by acting with an environmental action plan to learn and transfer the successful practices that the partners are carrying aut locally.For ESST Project , 5 EU member countries (Germany,Lithuania,Croatia,Spain,Italy) with a cordidate country (Turkey) schools have been met. These are successful practices to create environmental awareness by adopting local sustainability principles.They adopted the principle of “think global,act locally”fort he solution and prepared an EU sized sustainability education action plan under the coordination of the Turkish school. Each school has prepared a transnational education activity (LTT) fort the project within the framework of the practices and expertise they focus on locally (6 pieces).They will also take leadership in the tasks to be carrried out during the Project and in the outputs that will emerge.Topics to be covered in transnational education activities are climate change effects,nutrition,biodiversity,carbon footprint,energy and waste management (resycling) within the scope of environmental sustainability.A total of 120 students and 60 teachers will participate in the transnational trainings.Students will be selected from the 12-15 age range. Apart from this,schools will make and expand the activities they will perform locally within the framework of the activity plan prepared,open to all student groups.Qualitative and quantitative measurement tools that will be used for measuring Project objectives are also determined.These are;-Pre and post tests(Wise human test,what kind pf consumer you are)-Achievement tests at the end of the activity (Kahoot)-Written grades and caurse success of participating students.-Teachers evaluation reports and feedback after the activity-Number of students attending environmental clubs in schools.-Participant profiles in in-school and out of-school activities.-Activity minutes (Attendancy,duration,number of participants)-Numerical data of social media accounts (follawers,views,comments and likes)-Written and visual press news. The education and trainning outcomes that will emerge at the end of the Project are;-E-journal(3 months,6 issues)-Sustainability agenda-Mini greenhouses, seed libraries, project commemorative forests.-Intelligence game named Defeated Pollutant.-Sustainable recipes book.-Information corners with zero waste campaign.-ESST Project Effective Consumer Law.-eTwinning Project and potential quality labels -Social clubs and social media accounts they control-Sample lesson and activity plans , video,photographt etc. Materials.Within the framework of the Project is dissemination activity plan, the priority of the schools to be followed fort he target audience and stakeholders at the local level in the visibility of the Project, the promotion of the work done and the announcement of the results; all students at schools (4600) and their families,educational institutions in the immediate vicinity,local government agencies,relevant NGO’s.Transnationally, the website and social media addresses will be opened with the Project,and the eTwinning Project will be launched and implemented simultaneously with the Project within the scope 2020,eTwinning “Climate change and environmental challenges year.”
