    Inhalers for asthma and COPD in the US generate emissions equivalent to approximately 530,000 cars annually.

  • 2

    SABAs, ICSs, and ICS-LABAs account for 98% of inhaler-related emissions, with metered-dose inhalers being the highest emitters.

    Insurance coverage for dry powder inhalers is limited, with only 33% of plans covering dry powder SABAs.

  • 4

    Cost-sharing disparities exist, as dry powder inhalers often have higher out-of-pocket costs compared to metered-dose alternatives.

  • 5

    Market competition and pricing structures complicate efforts to reduce inhaler emissions and improve access to environmentally friendly options.
