There is growing awareness of the importance of addressing the interwoven crises of climate change, inequality and biodiversity loss. Education, as always, is seen as a critical component in addressing these challenges. The Green Templeton Lectures 2025 will explore the topic of sustainability education with speakers reflecting, in dialogue, on three critical and central issues. In this third session we will hear from Sam Barratt, Chief of the Youth, Education and Advocacy Unit at the United Nations Environment Programme, and Ann Finlayson, CEO of the charity Sustainability and Environmental Education (SEEd).
