Due to the industrial revolution, globalization and consumer society influx, our planet is going to be affected by a relevant climate change. This issue has become very important and places great challenges on societies and thus also on schools. The young generations are stimulated to run a new path. They want to show the whole world the importance of facing the problem and the need for younger generations to follow a common route. While “School Strike for Climate” focuses on demanding action from the authorities, we strongly believe that personal responsibility has crucial significance too. The current strategies of sustainability movement are assessed quite differently in the partner countries, and even a split in Europe is often evoked. We would like to inform ourselves about the motivation and consequences of irresponsible attitudes, discuss the relevant Goals set in the 2030 Agenda for Sustainable Development and shape a positive point of view towards sustainable approaches.
