PurposeThis study aims to describe the design process of two teacher professional development programmes on Climate Change Education in Chile and Mexico, their initial outcomes on teacher practices and feedback on course activities, content and format, and their expectations of future topics for deepening their understanding.Design/methodology/approachA systematization of the design and implementation process of both programmes was conducted. Subsequently, an online survey comprising 21 questions was administered to 115 teachers from both countries, representing 5% of the graduates from each programme. The survey evaluated their experiences, the impact on their teaching practices and the effects on their personal and professional lives. This non-experimental design relied on teachers' self-reported perceptions after completing the course.FindingsTeachers rated their experience highly, particularly regarding content quality and relevance to their local environment. Most (97.4%) applied their learning in their classrooms, with 78.3% noting it helped raise student awareness of climate change and facilitate collaborative projects. Additionally, 92.2% reported personal sensitization to climate issues and 87% changed personal habits. The course influenced 91.3% to take daily actions to reduce CO2 emissions. Some reflections are made on the design and implementation of the programmes, considering the survey results and the available literature.Research limitations/implicationsThe study relied on self-reported data from teachers after they had completed the courses. This approach was chosen because it allowed for a direct assessment of teachers' understanding and experiences. However, it is important to acknowledge the limitations inherent in self-reported data, such as the potential for response bias.Practical implicationsEducators, scientists and healthcare professionals can explore innovative pedagogical approaches to make CCE engaging and relevant, ensuring that all students not only comprehend the content but also feel empowered to contribute to environmental sustainability and learn to regulate their eco-anxiety. Teachers would have the opportunity to attend professional development courses based on research, reflect on their personal and technical habits, transform them, be role models for their students and build professional learning communities. Schools are transformative with a high quality of climate change education.Social implicationsClimate change demands urgent transformations in our consumption, energy generation and the construction of resilient cities. Education is pivotal in empowering environmentally conscious citizens. It fosters environmental awareness, develops skills to tackle climate challenges, promotes active citizenship, advocates for sustainable lifestyles and encourages innovation in clean technologies. By connecting people with nature, education strengthens environmental responsibility. Additionally, it equips society to advocate for sustainable policies and take action for the environment. A comprehensive educational approach is essential to forge global consensus and effectively address climate change.Originality/valueBy systematically evaluating teacher experiences and the impact on their personal and professional lives through detailed survey data, the study provides valuable insights into effective educational strategies for climate change awareness. Additionally, it highlights practical applications and behavioural changes among educators, contributing to the broader discourse on environmental education.
