The European Green Deal and UN Sustainable Development Goals (SDGs) highlight that education, including re-/up-skilling, is crucial in order to transition to environmental sustainability. Education has an essential role to play by supporting citizens in developing the competences needed to live responsibly, change consumption models, design solutions, transform society and shape a green economy. In the context of the EU’s efforts to promote a sustainable and green Europe, the purpose of this study is to map EU Member States’ national and institutional practices, processes, tools and strategies in education for environmental sustainability (EES) at various levels and in different forms of education. The study will help inform the actions of the European Commission with regard to education for environmental sustainability and policy for the implementation of the European Education Area and the European ‘Green Deal’.
