The climate crisis is rapidly unfolding with immediate, disastrous consequences including rising surface temperatures, melting of icecaps and glaciers, rising of sea levels, and destructive wildfires spanning the globe. The impact of these climate changes on human health is broad, ranging from immediate heat-related deaths to acute and chronic respiratory and cardiovascular illness. Ironically, the healthcare industry itself contributes to climate change in many ways including waste generation, energy consumption, pharmaceutical production, equipment manufacturing, transportation, and infrastructure. In addition to these obvious ways, the use of HFA-propelled MDIs contributes significantly to the climate footprint of healthcare and is easily addressed immediately by changing to DPIs and soft mist inhalers where feasible and appropriate based on patient needs, safety, and availability of inhalers. Implementing carbon offset programs, investing in research and development, and raising awareness among healthcare professionals are crucial components to reform. The healthcare industry must lead by example and commit to long term sustainable practices that not only mitigate the environmental footprint of the healthcare industry but also improve patient outcomes.
