Education and teachers are important factors to promote understanding of the European Union and construct the European identity. The “EU GreW” project aims to primarily train a transnational group of teachers that will act as inspiring social and cultural agents that will spread the European values to colleagues, young people and the society. Moreover, they will foster a dialogue with and among relevant stakeholders on a social and policy level and will contribute towards realising synergies and improving the quality of training and learning through knowledge about Europe and its values. The project aims to create a cross-border, sustainable and long-lasting teachers’ network, which will promote social and civic competences of pupils and advocate democratic values, fundamental rights, intercultural understanding and the ownership of them with a special focus on environmental policies and the promotion of sustainable development.
