Published by UNESCO, the report shows the potential for education to push progress towards all global goals outlined in the new 2030 Agenda for Sustainable Development. It also shows that education needs a major transformation to fulfill that potential and meet the current challenges facing humanity and the planet. The Report shows the need for education systems to step up attention to environmental concerns. While in the majority of countries education is the best indicator of climate change awareness, half of countries’ curricula worldwide do not explicitly mention climate change or environmental sustainability in their content. In OECD countries, almost 40% of 15-year-old students only have basic knowledge about environmental issues.
