Con­cern and engage­ment on cli­mate change is grow­ing across all ages. But how does that con­cern vary across age groups? Knowl­edge of an age dif­fer­en­tial can help us under­stand broad­er cit­i­zen engage­ment with cli­mate change action, but also the spe­cif­ic con­cerns, moti­va­tions, respon­si­bil­i­ties and engage­ment of dif­fer­ent cohorts. That more nuanced under­stand­ing could help gov­ern­ments, civ­il soci­ety groups and the pub­lic under­stand how cli­mate change might affect dif­fer­ent cohorts dif­fer­ent­ly, and why dif­fer­ent sorts of engage­ment might be more pop­u­lar or suc­cess­ful with dif­fer­ent groups. Youth cli­mate con­cern and action has recent­ly received con­sid­er­able atten­tion due to young people’s grow­ing involve­ment, their dis­tinct per­spec­tives and moti­va­tions, and their effec­tive strate­gies for mobi­liza­tion (Cripps 2022; Neas, et al 2022). But we know much less about the per­cep­tions and par­tic­i­pa­tion of old­er cit­i­zens (over 60s). This brief­ing seeks to address that gap.
