Abstract

Cardiovascular disease is one of the most common causes of mortality and morbidity in the UK and its ecological footprint makes a significant impact on the healthcare system overall. The NHS is one of the first national health system to commit to net-zero emissions by 2040, and exemplifies a growing global push toward sustainable healthcare. However, maintaining clinically safety and efficacious care is paramount, and balancing this with sustainability poses a challenge. While system-wide reforms require time and collaboration, many sustainable practices can be adopted immediately without affecting patient care. Ongoing research and robust data are necessary to support the safe integration of these environmentally conscious strategies into cardiovascular practice. This paper puts forward strategies that will enable sustainability and practical implementation at both an individual and departmental level, and a broader national level, with a focus on maintaining clinical standards.
