Modelling the climate impact of inhalers and mitigation strategies: a population-based study in British Columbia, Canada (2015-2032).

ABSTRACT:

Background

Canada has one of the highest per capita greenhouse gas (GHG) emissions, with healthcare contributing ~5% of the total. Pressurised metered-dose inhalers (pMDIs) are significant contributors due to their use of hydrofluorocarbon propellants. While propellant-free dry powder inhalers (DPIs) and soft mist inhalers (SMIs) are available, their adoption remains limited. This population-based study evaluates inhaler dispensation trends in British Columbia (BC), Canada, projects future dispensation and emissions over the next decade, and explores mitigation strategies through pMDI substitution.

Methods

Historical inhaler dispensation data (2015-2022) from BC were analysed using negative binomial models to assess trends, project future usage and emissions (2023-2032) and
