The Lancet Countdown, 2025
The latest Lancet Countdown report makes clear that climate change action offers a lifeline for health.
The report finds health risks and impacts of climate change are worsening, with millions dying needlessly each year due to fossil fuel dependence, growing greenhouse gas emissions, and failure to adequately adapt to climate change.
As some countries and companies rollback on climate commitments, local and grassroots leadership is building momentum for a healthier future, from the bottom up.
The report represents the work of 128 experts from 71 institutions, monitoring progress across 57 indicators – from heat-related deaths to bank lending to fossil fuels – providing the most comprehensive assessment yet of the links between climate change and health.
