Metered-dose inhalers: Small devices, big climate impact

While they are often used to treat common respiratory diseases, many inhalers contain hydrofluorocarbon propellants, potent GHGs that contribute to the health care sector’s climate footprint and threaten respiratory health. 

In this physician-led session, learn about the clinical use and climate impact of metered-dose inhalers and the benefits and challenges of switching to climate-friendly alternatives such as dry powder inhalers. Also hear about an approach to quantifying these emissions at the hospital and health system levels to clarify clinical practices and identify strategies to reduce climate impacts, including partnership with prescribing clinicians, pharmacists, and payers.
