PurposeThe current study examined the impact of population ageing on environmental quality in 17 late-demographic dividend (LDD) countries.Design/methodology/approachThe panel autoregressive distributed lag (ARDL) model using pooled mean group (PMG) estimator based on the environmental Kuznets curve (EKC) hypothesis was used to analyse data for the period 1990–2018.FindingsThe empirical results demonstrated that in the long run, carbon dioxide (CO2) emissions decrease with population ageing. The prevailing findings also indicated no sufficient evidence of EKC hypothesis validity and electricity consumption, which is the primary driving force of CO2 emissions in LDD countries.Originality/valueUnlike prior works, this paper is among the first to discuss environmental quality due to the current demographic transition towards ageing among LDD countries. Based on the results, population ageing reduces the environmental deterioration. The identification of possible ageing impact is vital to combat the climate change in order for countries to achieve sustainability, better economy and quality environment.
