Abstract
Climate change is a public health crisis predominantly due to fossil fuel combustion, that challenges planetary and human health. Considerable evidence exists to demonstrate the impact climate change has on cardiovascular disease primarily through air pollution, and non-optimal temperature. Conversely, healthcare systems themselves contribute substantially to climate change. Many clinicians personally report a sense of responsibility to reduce the detrimental impact of parts of our healthcare system on the environment. Roadmaps exist to guide decarbonization and reduce pollution in the healthcare sector. The first step in minimizing the climate impact of the provision of cardiovascular care is to determine the carbon footprint of highly resource dependent sectors such as critical care cardiology as well as the cardiac catheterization and electrophysiology laboratories. This should be followed by sustainable changes to address healthcare waste and energy use. Engagement from healthcare leadership, governmental organizations and major cardiac societies will be necessary to impact meaningful change.
