American Heart Journal Plus: Carbon Emissions and Air Pollution Savings Among Telehealth Visits for Cardiology Appointments

Climate change has been associated with adverse cardiovascular health, prompting interest in climate mitigation strategies while improving access for cardiovascular patients. This study estimated greenhouse gas and air pollution savings from telehealth use in cardiology. Over 45 months, 14,828 telehealth visits among 9942 patients resulted in savings of 484,152 kg of CO₂, 5225 kg of CO, 243,491 g of NO_x, and 9091 g of PM_2.5 with the total carbon saved equivalent to planting 9070 tree saplings over ten years.
