The 2025 data from the Lancet Countdown on Health and Climate Change highlights current and growing threats to the UK that need urgent action. The report reveals:
- Rising temperatures are amplifying health and productivity risks, as heatwaves increasingly affect vulnerable populations and workers across multiple sectors
- Climate extremes are intensifying, with wildfires, drought, and air quality impacts emerging as growing threats even in a temperate climate.
- Decarbonisation is advancing but uneven, as the UK phases out coal and reduces pollution, while overall emissions and the health sector’s footprint remain substantial.
The UK Health Alliance on Climate Change supported by colleagues from the British Medical Association, Royal College of Nursing and Plant Based Health Professionals UK led on the production of the UK policy priorities drawing evidence from the Lancet Countdown evidence.
They call for urgent action in the UK to protect health from climate change through measures including:
- Phasing out fossil fuels and scaling up renewable energy to cut air pollution, reduce heat risks, and lower energy costs
- Promoting healthier, plant rich diets to improve health, cut emissions and reduce food insecurity
- Significantly increasing protected adaptation funding to protect health and ensure health system resilience
Together, these actions will save lives, reduce costs, and secure a healthier future for all.
