Educational institutions can play a significant role in the fight against climate change. The EU-funded ECF4CLIM project will develop, test and validate a European Competence Framework (ECF) for transformational change to empower the educational community to act. The project will apply an innovative hybrid approach based on participatory action research and citizen science to co-design an ECF that is adaptable to a range of settings and integrates digital and social competences related to science, technology, engineering and mathematics. ECF4CLIM explores individual, organisational and institutional factors. To encourage learning-by-doing, several innovative tools will be co-designed with and made available to citizens, including a digital platform for crowdsourcing, IoT solutions and a digital learning space.change, which will empower the educational community to take action against climate change and towards sustainable development.
