The NEED to mitigate the climate change is urgent and our schools are committed to this UN SDG. As irresponsible consumers, young people were aimed to be involved in a range of activities planned to increase their awareness about the harm they cause the environment and daily actions they can adopt to reduce it. The analysis of the questionnaire applied to partner school pupils and their families prove the claim. Therefore, increasing awareness of consumption in order to mitigate the impact of human activities is vital for global CLIMATE JUSTICE. Previous eTwinning projects enabled the partnership to deal with the case but the problem was global. Therefore, with international cooperation, we wanted to overcome the challenge and increase awareness to the highest point in the society and to include more educational communities. This is also an Erasmus+ project.
