According to the 2019 report of the Lancet Countdown on health and climate change, the Human wellbeing, the stability of local communities, health systems, and governments, all depend on how they interface with the changing global climate. An average temperature increase has already resulted in extreme climatic and environmental changes. Left unabated, climate change will define the health profile of current and future generations, challenge already overwhelmed health systems, and undermine progress towards the UN SDGs and UHC. Education is a critical agent in addressing the issue of climate change. It encourages people to change behaviour and helps them make informed decisions. It paves the way for the implementation of the future European Climate Law. Carbon Act suggests a bottom-up approach, including three complementary blocks of activities aiming to develop a set of exemplary practices and guidelines for introducing climate change in the classroom and to ensure their large-scale dissemination and uptake:1.A foundational phase, including desk research into existing climate change initiatives, and development of a curriculum analysis for introducing climate change into schools2.A Piloting Phase, co-development of learning scenarios on the topic which will feed into an online catalogue and MOOC for the large-scale implementation in countries across Europe3.The large-scale deployment phase, development and running of a MOOC, a set of videos, a competition, and a final report, meant to ensure participation of schools and institutions interested in bringing climate change to STEM teaching and strategies at the school levelVia its intellectual outputs and activities, the project will have an impact on:A/ Schools, teachers, and pupils – MOOC to potentially reach a minimum 1000 teachers (and an additional 12000 students) B/ Impact at the level of research institutionsC/ Impact beyond the project at policymaker level and at systemic levelD/ Structural impact
