This article reconceptualises sustainability as being built upon a foundation of environmental consciousness and understanding. It explores the current thinking around education for sustainability to offer an alternative curriculum view: a view where sustainability permeates throughout the primary curriculum and is driven by pedagogies that offer children opportunities to grow their confidence, challenge ideas and offer solutions to the local, national and, ultimately, global problems they will face through their lifetime. By increasing children’s sustainability capital and their agency towards these challenges, we can reduce eco‐anxiety.
