Policies for healthy ageing in response to climate change: Protocol of a systematic review

PLOS One | https://doi.org/10.1371/journal.pone.0323069 April 30, 2025 6 / 8 experts in those contexts will be invited. All experts and corresponding authors invited will be given access to documents included in the review. Discussion and conclusion Older adults are disproportionately affected by climate change, so programmes aimed at meeting their unique needs in contexts experiencing extreme climate events are essential. Researchers [29–31] have acknowledged a need for countries to adopt healthy ageing policies that protect older adults from climate crises, and the literature shows a range of healthy ageing policy responses to climate change [32,33]. This systematic review compiles healthy ageing policies that are cognisant of climate change, giving stakeholders insight into the purpose of these policies and who they are targeted at. A systematic review allows us to demonstrate the highest level of rigour in our search, scrutiny, and report- ing of the relevant evidence. This review will reveal contexts where the development of healthy ageing policies in response to climate change should be prioritised. By compiling evidence on a global scale, this review will depict the geographic scope of ageing policy responses to the climate crisis. The review may provide an understanding of the role of healthy ageing policies in public health promotion during climate change. Finally, this review will highlight areas where future research and policy dialogues are needed for fostering healthy ageing. Supporting information S1 Appendix 1. This is the S1 Appendix 1 Title.
