Working from home saves approximately 600 kilograms of CO2 per year per worker (-40%) while saving time (approximately 150 hours), distance traveled (3,500 km), and fuel (260 liters of petrol or 237 liters of diesel), according to an ENEA study published in the international journal Applied Sciences on the environmental impact of remote working in Rome, Turin, Bologna, and Trento over the four-year period 2015-2018. "In our country, about one in every two people owns a car, or 666 cars per 1,000 inhabitants, ranking Italy second in Europe only to Luxembourg in terms of motorization rate," explained Roberta Roberto, ENEA researcher at the Department of Energy Technologies and Renewable Sources and co-author of the survey with Bruna Felici, Alessandro Zini, and Marco Rao.In Italy, transport generates over 25% of total national greenhouse gas emissions, of which 93% from road transport, with cars accounting for the largest share (70%). "Remote working has proven to improve work-life balance, reduce traffic and urban air pollution, and revitalize entire suburban areas and neighborhoods that were previously considered dormitories," Roberto said.
