Since their launch in September 2015, the UN’s Sustainable Development Goals(SDGs) have been increasingly taken up by schools as both an educational theme and learning tool. A growing number of teachers around the world are seeing the SDGs, also known as the Global Goals for Sustainable Development, as a powerful and engaging theme inside and outside of the classroom. There have been a number of initiatives, policies and organisations pushing for greater awareness of the 17 SDGs aimed at ending poverty, protecting the planet and ensuring prosperity for all. Some drivers originate from the UN itself (e.g. UNESCO policy such as the recent ‘Building sustainable peace and global citizenship through education’), some have been created collaboratively by global education NGOs (e.g. the World’s Largest Lesson), whilst others are emerging organically among teachers through international social media movements such as #TeachSDGs.
