Impact on the reduction of CO2 emissions due to the use of telemedicine.

Digital health can reduce CO emissions thanks to telemedicine and access to digital test results and medical reports. However, the environmental impact of digital health activity is not well known. Here, we show that telemedicine reduces CO emissions. We found a net total of 6,655 tons of CO emissions decrease through a reduction in patient travel to surgeries and medical clinics thanks to the alternatives of digital appointments and digital access to test results and medical reports, which avoid the need to travel to a clinic for a face-to-face visit or to pick up printed results or reports. During 2020, a total of 640,122 digital appointments were carried out by the health care company, which avoided 1,957 net tons of CO emissions, while patients downloaded 3,064,646 digital medical reports through the company portal, which avoided an additional 4,698 net tons of CO emissions. Our results demonstrate how digital appointments and digital reports, reduce CO emissions by reducing the need for patient travel.
