Editorial: COP26 and public mental health

As we prepare for COP26 in Glasgow next week, we recognise the huge responsibility on world leaders to urgently take action on climate change to save our planet. Given the coverage in recent weeks, we have also become even more aware of the enormous impact of climate change on the well-being of communities all around the world. This includes an increasing focus on the mental health impact of climate crisis and the need for the public mental health community to refocus our efforts on addressing this.

On this theme, this issue begins with a paper on the connection between mental health and the environment, entitled "Three Good Things in Nature: A Nature-Based Positive Psychological Intervention to Improve Mood and Well-Being for Depression and Anxiety" by Rosaline Keenan and colleagues. It discusses the effectiveness of this innovative programme and highlights the potential for scaling up nature-based psychological programmes.
