The 2017 Report of the Lancet Countdown

The Lancet Countdown's 2017 report tracks 40 indicators across five areas, arriving at three key conclusions:

  • The human symptoms of climate change are unequivocal and potentially irreversible`
  • The delayed response to climate change over the past 25 years has jeopardised human life and livelihoods.
  • The past 5 years have seen an accelerated response, and in 2017 momentum is building across a number of sectors; the direction of travel is set, with clear and unprecedented opportunities for public health.


See our indicators for a more thematic breakdown of the report:

Climate Change Impacts, Exposures and Vulnerability

Climate change undermines the foundations of good health, affecting populations around the world, today. Whether through extremes of weather, the spread of infectious disease, or threats to food and water security, these effects are disproportionately felt by those who are most vulnerable, and people in low- and middle-income countries.

Indicators and headline findings

Adaptation Planning and Resilience for Health

Numerous cost-effective solutions exist to adapt to climate change and improve public health resilience. Whilst some progress has been made, there more work and resource is urgently needed.

Indicators and headline findings

Mitigation Actions and Health Co-Benefits

Responding to climate change yields immediate and tangible benefits for human health, cleaning up polluted air, ensuring healthier diets, and encouraging physical activity. These interventions result in a healthier population, helping to reduce costs for often over-burdened healthcare systems.

Indicators and headline findings

Finance and Economics

Early signs of investment in renewable energy and coal-fired power suggest the beginning of a broader transition maybe underway. Accelerated economic policy and spending is essential to deliver on this promise, and secure the health benefits it offers.

Indicators and headline findings

Public and Political Engagement

Implementing the Paris Agreement depends on enhanced engagement from the public and policymakers. Health professionals have an important role to play, ensuring that climate change is understood as an issue that is central to health and wellbeing.
