Education for sustainable development gives learners of all ages the knowledge, skills, values and agency to address interconnected global challenges including climate change, loss of biodiversity, unsustainable use of resources, and inequality. It empowers learners of all ages to make informed decisions and take individual and collective action to change society and care for the planet. ESD is a lifelong learning process and an integral part of quality education. It enhances the cognitive, socio-emotional and behavioural dimensions of learning and encompasses learning content and outcomes, pedagogy and the learning environment itself.

Climate change education is the main thematic focus of ESD as it helps people understand and address the impacts of the climate crisis, empowering them with the knowledge, skills, values and attitudes needed to act as agents of change. The importance of education and training to address climate change is recognized in the UN Framework Convention on Climate Change, the Paris Agreement and the associated Action for Climate Empowerment agenda which all call on governments to educate, empower and engage all stakeholders and major groups on policies and actions relating to climate change. Through its ESD programme, UNESCO works to make education a more central and visible part of the international response to climate change. It produces and shares knowledge, provides policy guidance and technical support to countries, and implements projects on the ground.
