The United Nations have declared climate change is one of the major challenges of our time. In that context, teachers require educational resources as well as professional development to be able to offer climate change education to their pupils. The Office for Climate Education (OCE) is a foundation hosted by the Fondation La main à la pâte to promote climate change education in developed and developing countries. The OCE became an official UNESCO center in 2020 with the aim to organise a strong international scientific, educational and operational cooperation for Climate Change education. The OCE offers to primary and middle schools’ teachers free and interdisciplinary educational resources, as well as professional development opportunities and field accompaniment based on IPCC “Assessment reports” and “Summaries for policy-makers”. These teaching resources are free, interdisciplinary, adapted to local needs, widely spread, translated in many languages and facilitate an active pedagogy. Based in Paris, the Office for Climate Education works with a global network of local or regional partners in over 40 countries. The Office for Climate Education began in 2018 as a foundation under the aegis of La main à la pâte Foundation, and founded by the Institut Pierre Simon Laplace (IPSL), the Institut de Recherche pour le Développement (IRD), Météo-France, and Météo & Climat, in partnership with the Potsdam Institute for Climate Impact Research (PIK) and the Siemens Stiftung.
