    PurposeInternational partnerships have an important role in capacity building in global health, but frequently involve travel and its associated carbon footprint. The environmental impact of global health partnerships has not previously been quantified.MethodsWe conducted a retrospective internal audit of the environmental impact of air travel for the international education programs of the Canadian Anesthesiology Society's International Education Fund (CASIEF). We compiled a comprehensive list of volunteer travel routes and used the International Civil Aviation Organization Carbon Emissions Calculator, which considers travel distance, passenger numbers, and average operational data for optimized estimates. Comparisons were made with average Canadian household emissions and disability adjusted life years (DALYs) lost from climate change consequences.ResultsThe total carbon dioxide emitted (CO2-e) for the Rwanda, Ethiopia, and Guyana CASIEF partnerships were 268.2, 60.7, and 52.0 tons, respectively. The DALYs cost of these programs combined is estimated to be as high as 1.1 years of life lost due to the effects of CO2-e. The mean daily carbon cost of the average Rwanda partnership was equivalent to daily emissions of 2.2 Canadians (or 383 Rwandans), for the Guyana partnership was equivalent to 1.6 Canadians (or 7.6 Guyanese people), and for the Ethiopia partnership was equivalent to 2.4 Canadians (or 252 Ethiopian people).ConclusionsAir travel from these CASIEF partnerships resulted in 380.9 tons CO2-e but also enabled 5,601 volunteer days-in-country since 2014. The estimated environmental cost needs to be balanced against the impact of the programs. Regardless, carbon-reduction remains a priority, whether by discouraging premium class travel, organizing longer trips to reduce daily emissions, prioritizing remote support and virtual education, or developing partnerships closer to home.© 2023.
