Decarbonizing energy use and enhancing efficiency can rapidly reduce greenhouse gas emissions in veterinary practice

Energy use is a major driver of greenhouse gas (GHG) emissions in veterinary practice, primarily through consumption of fossil fuel-generated electricity and heating, client travel, staff commute, and the extensive supply chain of healthcare products. Here we synthesize information on these key emission sources, outline the scientific and economic rationale for decarbonizing energy use and present 6 scalable strategies for reducing energy-related emissions in veterinary hospitals: procuring 100% renewable low-carbon electricity, electrifying clinical operations and infrastructure, reducing transport-related emissions, improving hospital energy efficiency, installing on-site renewable energy generation and storage, and addressing emissions from procurement and delivery. Together, these interventions provide a structured pathway for reducing emissions from veterinary practice while strengthening operational resilience, supporting long-term financial sustainability, and advancing the profession's role in protecting the health of animals, people, and the environments they share, consistent with a One Health approach.
