Advisory Groups

The work of the Lancet Countdown is guided by global experts in health and climate change. Academic outputs are overseen by the Scientific Advisory Group and a newly established High Level Advisory Board will provide strategic direction for the Lancet Countdown’s policy engagement and communications work.

It is with great sadness that we acknowledge the passing of Peter Byass and Georgina Mace, both of whom were instrumental to the formation of the Lancet Countdown and its ongoing scientific and strategic direction. Peter, who was a world-leading global health expert, sat on the Board of the Lancet Countdown and co-chaired Working Group Two: Adaptation, Planning, and Resilience for Health. Georgina, a world-leading expert in biodiversity and ecosystems, was a member of the Lancet Countdown’s Scientific Advisory Group.
