The 2023 Global Report of the Lancet Countdown


The latest Lancet Countdown report underscores the imperative for a health-centred response in a world facing irreversible harms.

Climate inaction is costing lives and livelihoods today, with new global projections revealing the grave and mounting threat to health of further delayed action on climate change. But bold climate action could offer a lifeline for health.

This year’s report launches just weeks before the COP28 which has a health focus for the first time. The findings underscore the opportunity of a lifetime that COP could help deliver – through commitments and action to accelerate a just transition. Without profound and swift mitigation to tackle the root causes of climate change and to support adaptation efforts, the health of humanity is at grave risk.

Our 2023 Report tracks the relationship between health and climate change across five key domains and 47 indicators, providing the most up-to-date assessment of the links between health and climate change.
