Leveraging climate actions for healthy ageing

As China’s population ages rapidly, the health risks associated with a changing climate are becoming more threatening. The 2022 China report of the Lancet Countdown, led by Tsinghua University with the contributions of 73 experts from 23 leading global institutions, tracks progress in climate change and health in China through 27 indicators across five domains: (1) Climate change impacts, exposure, and vulnerability; (2) adaptation, planning, and resilience for health; (3) mitigation actions and health co-benefits; (4) economics and finance; and (5) public and political engagement. This report is the third China Lancet Countdown report, paying particular attention to the impacts on the elderly and highlighting the urgency of taking action. We selected the most urgent and relevant indicators to complete a policy brief that provides a better understanding of recent progress on climate change and health in China. We found heat-related health impacts increased from 2020 to 2021, increasing heat-related mortality, reducing labour capacity, and undermining the capacity to partake in physical activity due to rising temperature. In addition, exposure to wildfire, extreme drought, and extreme rainfall also increased in different regions across China. In 2021, compared with the 1986–2005 average, people in China had an average of 7.85 more heatwave days (which led to an extra 13185 heatwave-related deaths), and a loss of 0.67 more hours of safe outdoor physical exercise per day. The rising temperature also caused the annual average exposure to wildfire to increase by 60.0% between 2017–2021 compared with the 2001–2005 average. Meanwhile, the engagement on health and climate issues from individuals, scholars, and public sectors continues to grow rapidly. From 2020 to 2021, the number of climate-related articles and documents on the official websites of four Chinese Government departments grew by 1.83 times, and the number of climate-and-health-related articles and documents gr
