The carbon footprint of healthcare is significantly impacted by intensive care units, which has implications for climate change and planetary health. Considering this, it is crucial to implement widespread efforts to promote environmental sustainability in these units. A literature search for publications relevant to environmental sustainability of intensive care units was done using PubMed. This mini-review seeks to equip intensive care unit practitioners and managers with the knowledge necessary to measure and mitigate the carbon cost of healthcare for critically ill patients. It will also provide an overview of the current progress in this field and its future direction.
Core Tip: To achieve environmental sustainability in the intensive care unit (ICU), healthcare professionals must have the knowledge and tools to measure and mitigate the carbon cost of healthcare for critically ill patients. Two complementary methods have been used in the ICU to measure the environmental cost of critical care: Life cycle assessment and material flow analysis. Various methods can decrease waste generation in the healthcare industry, such as preventing the progression of illnesses and inpatient admissions, avoiding unnecessary ICU admissions, minimizing overdiagnosis and over-investigation, and curtailing overtreatment. Interventions can also focus on reducing energy consumption and reusing/recycling products.
