amp; Chen, 2024). In 2007, Garry Haq and others called for deeper interest in climate change, later labelling the emerging field as ‘climate gerontology’ (Haq et al., 2014). In 2011, Karl Pillemer, among others, stressed the importance of broadening the meaning of ‘the environment’ in gerontology. Not only human-made, built environments, homes and neighbourhoods, but also environmental issues, ecological decline, or sustainability challenges older people face, should be covered by gerontological research. Most sources that use this broader concept of the environment or that focus on climate change were published around 2020 and after. Despite this relative boom, the multifaceted relationship between population ageing and environmental change remains under-researched. In retrospect, we might, along with other recent ‘turns’ in gerontology or the sociology of ageing (e.g., post-colonial, post-humanist, or new materialist), label this broader shift in focus and reconceptualisation as a ‘new environmental turn’.
