Abstract:
Climate change threatens to undo all the advances made in public health over the last 50 years. Healthcare systems contribute significantly to greenhouse gases and must adapt if they are to be sustainable. Metered dose inhalers (MDIs) have been highlighted as a particular issue due to their hydrofluorocarbon (HFC) propellants, which are potent greenhouse gases. Effective alternatives are available in the form of dry powder, and aqueous mist inhalers and research is already underway on alternative propellants for MDIs. Small volume or HFC 134a-containing inhalers have smaller carbon footprints than large volume and HFC 227ea inhalers. Other strategies to reduce greenhouse gas emissions are discussed, including inhaler recycling and more efficient use of inhalers. Switching to low global warming potential inhalers will be required to meet sustainability targets and help avoid some of the worst health effects of climate change.
