The project involves six European preprimary and primary schools from Belgium, Finland, Greece, Italy, Romania and Spain and focuses on the UN Sustainable Development Goal (SDG) number 13 – climate action. This eTwinning project is a part of our Erasmus+ KA229 project 2020-2022 “Friends for Our Planet!”. With our project we will focus on 6 subthemes: energy, waste, air pollution, preserving nature, biodiversity and water. More schools are invited to join in to work together in the TwinSpace.
