The physician's role in mitigating the climate crisis

Climate change is a growing concern and healthcare is simultaneously being burdened with worsening climate-related health conditions, while significantly contributing to emissions and temperature rises. Studies have documented the effects of emissions on increasing numbers of early deaths, while rising temperatures and altered rainfall patterns lead to a change in vector migratory patterns alongside broader physical and mental health impacts. These changes only exacerbate the current global health inequities. The role of doctors in reducing the burden of the climate emergency can not be understated, including both individual and systemic changes. Preventative medicine can promote an active lifestyle and reduce fossil fuel consumption, while patient education and empowerment on reducing red meat consumption can improve cardiovascular health and reduce emissions. Low carbon solutions can be achieved via smarter prescribing and lean pathways can increase efficiency. It is in everyone's interests for physicians to adjust their practice to improve sustainability.
