In this project, we will learn about how climate change occurs and what we can do to prevent it. Our students will explain how we can be more responsible to help planet Earth reduce carbon emissions in our daily lives using web 2.0 tools. This is an international project and only students between the ages of 12 and 18 will be accepted. As a result of the project, the participating students will receive eTwinning certificates, which will be produced through the joint work of their own institutions, with co-signatures. The results of our project will be announced to a wide audience on social media channels such as Twinspace, Facebook, Instagram, Youtube and on school websites.
