This project is about our care concerning the environment and its sustainability. This is a partnership between five schools from Estonia, Denmark, Latvia, Iceland and Portugal. It will involve 160 students (age 14 to 16) and 50 teachers. Within the partnership we will collaborate with local stakeholders.We are are working together on the topic of sustainability/ good practices from the five different national viewpoints. The main objectives are: 1) To share good environmental practices from each community; 2) Getting to know distinct national environmental issues; 3) Figuring out ways for improvement and changing lifestyles. The material results will be an educational video that teachers and students can use during lessons in all countries. We will use different platforms including eTwinning, which will be our major platform for students' communication.
