Green Perspectives in Radiation Oncology.

The health care sector contributes 4.4% of global greenhouse gas emissions. Many countries are aiming for a carbon net-zero health care system by 2040-2050. Climate-smart practices in radiation oncology units include a progressive shift towards stereotactic body radiotherapy, the use of telemedicine, and strategies to streamline treatment workflows. Integration of geographic appropriateness in health care policies can also significantly mitigate the carbon footprint of clinical practice. Our rapid review assesses the environmental impact of climate-smart practices in radiation oncology departments, with a focus on management of prostate cancer. PATIENT SUMMARY: Health care accounts for a significant proportion of greenhouse gas emissions. A number of actions are already possible in radiotherapy departments to limit their environmental impact, such as reducing the number of radiotherapy sessions, simplifying treatment planning, and using telemedicine. These strategies should be combined with government measures to ensure that all cancer patients have access to local care centers.
