About The Study: Inhaler prescriptions filled by Centers for Medicare & Medicaid Services beneficiaries in 2022 resulted in an estimated 1.15 million metric tons of carbon dioxide equivalent emissions, equivalent to 226,960 homes’ yearly electricity use. Metered-dose inhalers were responsible for nearly all inhaler-related emissions, with the largest contribution arising from short-acting β-agonist medications. Although dry-powder and soft-mist inhalers had substantially lower emissions, they accounted for a disproportionate amount of spending, representing nearly two-thirds of inhaler costs but only one-third of claims.
