BackgroundThe healthcare sector, while dedicated to improving health, paradoxically contributes significantly to global carbon emissions, accounting for approximately 4.9% of global emissions. Despite growing public concern about climate change, few studies have explored patients’ awareness and attitudes toward the environmental impact of healthcare. This study aims to assess patients’ perspectives on climate change and the sustainability of healthcare practices.MethodsA cross-sectional survey was conducted at Ludwig-Maximilians-University (LMU) Hospital in Munich, Germany. Patients were invited to participate in a voluntary, anonymous online survey via strategically placed QR codes throughout the hospital. The survey explored patients’ demographic information, environmental awareness, attitudes toward climate-friendly practices in healthcare, and willingness to support sustainable initiatives. Descriptive statistics and regression analyses were used to analyze the data.ResultsA total of 399 patients completed the survey (87% completion rate). The majority of respondents (92.3%) were aware of climate change, and 82.7% reported prioritizing climate-friendly practices in their personal lives. However, 55.9% of respondents were unaware of the healthcare system’s contribution to carbon emissions, and only 18.3% knew about hospitals’ climate impact. Despite this, 88.2% of respondents supported environmentally friendly initiatives in hospitals, and 86.5% were open to sustainable alternatives, provided that quality standards were maintained. Participants expressed significant interest in knowing the environmental impact of their treatments, with 63.2% in favor of a Nutri-Score-like system that would display the carbon footprint of medical procedures. Among those, 54.4% indicated that such a system would influence their choice of treatment. Similarly, 62.2% of respondents were interested in knowing the environmental impact of their medications, with 65% reporting that this information would affect their medication choices. A notable proportion of patients (66.2%) indicated willingness to support sustainable healthcare through shorter hospital stays and increased follow-up visits, while 35.8% were open to paying a CO2 compensation fee for their treatments. However, 81% were unwilling to pay higher insurance premiums to support environmentally friendly practices in hospitals. Regression analyses revealed that older age groups and having children were positively associated with environmental awareness (p |
