Climate concern, pro-environmental behaviours and use of e-cigarettes in the European Union

This study examined whether broader environmental orientations are associated with current e-cigarette use and disposable e-cigarette use in the European Union (EU). We analysed data from Special Eurobarometer 99.3 (2023) across 27 EU Member States (n = 26,353), measuring environmental orientations via climate concern and pro-environmental behaviours. Climate concern was associated with lower likelihood of e-cigarette use (Prevalence Ratio = 0.84, 95% CI, 0.72-0.99); pro-environmental behaviour was associated with a lower likelihood of disposable e-cigarette use (0.72,0.53-0.99). Both estimates were attenuated in sensitivity analyses; the latter relied on a small subgroup. Findings should be considered exploratory. Further research using product-specific environmental measures is warranted.
