Beyond Do No Harm: Introduction to Green Radiology.

Abstract

Abstract: In 2021, the Human Rights Council declared that having a clean, healthy, and sustainable environment is a human right. According to the WHO, 24% of deaths are attributable to environmental health risks and are largely preventable. Current predictions show that rising emissions will be linked to an enormous healthcare burden, especially for high-risk populations and historically disadvantaged communities. The US healthcare industry accounts for nearly 18% of its GDP and is a major consumer of resources. The largest healthcare-related source of greenhouse gas emissions is from the supply chain, including pharmaceuticals, other chemicals, food, and the transportation required to mobilize them accounting for 80% of emissions, with only 20% of emissions from purchased energy and the facilities directly. As a field, radiology has historically monitored its impact in terms of radiation exposure and thermal effects but has not focused on other pollutants, greenhouse gas emissions, or waste. Although tackling large issues such as climate change and pollution seems daunting, we can start by raising awareness through education, investigation, and advocacy. In this review, we discuss a systems-based approach to addressing climate change from the federal to the local level focusing on the potential role of the radiologist.
