The Lancet Countdown on Health and
Climate Change

The Lancet Countdown: Tracking Progress on Health and Climate Change is an international research collaboration, dedicated to tracking the world's response to climate change, and the health benefits that emerge from this transition. Reporting annually in The Lancet, it will follow a series of indicators, demonstrating that this transition is possible, that it has already begun, but that more work is needed.

The Report Resources

Wellcome are a global charitable foundation, both politically and financially independent, supporting over 14,000 people in more than 70 countries. They allow scientists and researchers to take on big problems, fuel imaginations, and spark debate, with the aim of improving health for everyone. They are committed to developing an evidence base that clearly demonstrates the connections between global environmental change and health, but importantly also to supporting solutions and action. The Wellcome Trust is a strategic partner for the Lancet Countdown, providing financial and technical support for its work.



The Lancet journals are a major contributor to health and medical media coverage worldwide, consisting of a weekly journal, The Lancet, plus nine monthly specialty journals. Since 1823, the journal has strived to make science widely available so that medicine can serve, and transform society, and positively impact the lives of people. The Lancet has been a leading actor in health and climate change, and acts as the convening organization for the Countdown's academic partners, and the publisher of its technical outputs.

Our background

The Lancet Countdown builds on the success of the 2015 Lancet Commission on Health and Climate Change, which highlighted that ‘tackling climate change could be the greatest global health opportunity of the 21st century’. It exists as a collaboration between academic institutions across the world, working to provide a global overview of the relationship between public health and climate change. The Lancet Countdown works closely with the World Health Organization's national efforts and their Climate and Health Country Profiles. It strives to communicate its research to health professionals and the broader health community, with an understanding that doctors, nurses, and allied health professionals have a pivotal role to play in ensuring that the response to climate change strengthens public health.

Academic Partners

UN Partners

The Lancet Countdown works in special collaboration with the World Health Organization and the World Meteorological Organisation, to deliver the academic and monitoring outputs, promote synergies with the WHO Health and Climate Change Country Profiles, collaborate on data sources, and ensure strong engagement with Ministries of Health.
