The Lancet Planetary Health is a monthly, open access, online-only title in The Lancet's growing family of specialty journals. Building on the foundation of The Rockefeller Foundation-Lancet Commission on planetary health, the journal is committed to publishing high-quality original Research Articles, Editorials, Comments, and Correspondence that contribute to defining and advancing planetary health worldwide.

Planetary health has been defined as the health of the human civilisation and the state of the natural systems on which it depends.

To explain this idea in simple terms we need to think of humanity as one of the key driving forces of global environmental change. We live on a planet that is shaped by the activity of human beings. We have benefited from the exploitation of the natural resources of the environment, and this has allowed us to develop, flourish, and to improve our health. But, we have now gone beyond a sustainable limit. The planet we live in is in grave danger. Species are under pressure. The environmental changes to the climate, the water, the land, and ecosystems are challenging life on the Earth with serious implications for our health and wellbeing. The way we think about the planet needs to be revised and with it the approach we take to interact with it.

It is against this backdrop that we welcome The Lancet Planetary Health. In keeping with our other journals, The Lancet Planetary Health will offer rapid publication of research online within 8-12 weeks from submission. We invite all original research submissions that have the potential to change or challenge the interplay between the environment and human health. We take a broad and inclusive approach to planetary health, and we especially wish to emphasise our interest in interdisciplinary and transdisciplinary research.

Submissions are subjected to The Lancet's usual rigorous standards of external and statistical peer review, and are edited by experienced copy editors to the highest standards. All original research remains the property of the author, and reuse by others is permitted under either CC BY or CC BY-NC-ND Creative Commons licences, depending on authors' preferences or funding bodies' mandates.
