INTRODUCTION: The impact of climate change on health and the necessity to reduce emissions in the health sector is becoming an increasingly discussed topic. Little is known about medical doctors' (MDs) attitude towards climate protection measures in outpatient practices. METHODS: Between October 2020 and February 2021, a survey was conducted among MDs in German practices. 1,683 participants answered 39 questions on energy use, transportation, disposable materials, budget and patient counselling. Data were collected on status, motivation, obstacles and needs regarding climate protection in practices. RESULTS: 83% considered climate change an urgent problem requiring immediate action. A majority reported climate effects on their patients' health. Most MDs felt responsible for climate protection in their practices, showing a high degree of willingness to implement climate-friendly measures. Obstacles reported include lack of information and institutional support as well as the expected financial burden. A majority of MDs called on professional associations and politics to develop climate-friendly strategies. CONCLUSION: In view of national climate targets and the willingness of outpatient MDs to contribute to climate protection, support from medical associations is required, e. g. through practical recommendations and financial help, in order to transform the health sector in accordance with the idea of Planetary Health. Accompanying studies should provide further evidence on effective measures to reduce greenhouse gas emissions in practices.      «
