Samenvatting

Efforts to create age-friendly cities progressively intersect with goals for environmental sustainability. The older people’s beliefs, behaviours and financial aspects regarding environmental sustainability in their lives are an understudied topic and not well understood. Therefore, a representative survey was conducted using the psychometrically sound and comprehensive SustainABLE-16 Questionnaire. A total of 388 respondents, who were community-dwelling older people in The Hague, filled out the survey completely. Overall, the mean scores on the SustainABLE-16 for finance- and environment-driven pro-environmental behaviours, beliefs and the financial position among older people were positive for all districts of The Hague. Using the outcomes of the survey, a total of six unique typologies were identified through a two-step process combining hierarchical and k-means cluster analyses. These six typologies are 1 the staunch non-believers, 2 the finance-driven non-believers, 3 the everyday individuals, 4 belief-driven people with limited financial resources, 5 believing non-responders, 6 the affluent and engaging people. These six typologies each require different approaches from policymakers. Sustainabilityrelated policies should ideally focus on groups with high scores for pro-environmental behaviours but who have shortcomings in knowledge how to improve one’s everyday lifestyle and groups who lack the necessary financial means to live a more sustainable life.
