This research report presents the findings of the 2024 Climate Literacy Survey, commissioned by the Department for Education (DfE) to assess the level of climate literacy amongst school leavers leaving secondary education in England. The survey, conducted with a sample of 522 Year 11 school leavers, aimed to: (1) Monitor changes in school leavers' understanding of climate change topics over time; and (2) Understand the potential impact of policies set out in the DfE's Sustainability and Climate Change Strategy. The survey comprised 55 questions, including five core questions from the Royal Meteorological Society's (RMetS) 2022 survey and 50 new questions developed in collaboration with the RMetS and Ipsos. Baseline knowledge and perceptions of climate change indicated that just over half of the school leavers that had taken part in the survey, recalled recent climate change education (55%), despite its inclusion in GCSE science and other subjects.
