Opting for hybrid working or work from home can result in a reduced carbon footprint compared to full-time office work, according to a new study.
Published in the Proceedings of the National Academy of Sciences, the study found that hybrid workers who work from home two to four days per week can reduce their carbon footprint by 11 percent to 29 percent, but working from home one day per week is cutting carbon footprint by only 2 per cent.
The study, conducted by researchers at Cornell University and Microsoft, used survey data and modelling to incorporate factors sometimes overlooked when calculating carbon footprint, including residential energy use based on time-use allocation, non-commute distance and mode of transportation, communications device usage, number of household members and office configuration, such as seat sharing and building size.
“Remote work is not zero carbon, and the benefits of hybrid work are not perfectly linear,” said study senior author Fengqi You, a professor in energy systems engineering at Cornell.
The study found that seat sharing among hybrid workers under full-building attendance can reduce carbon footprint by 28 percent. Hybrid workers tend to commute farther than onsite workers due to differences in housing choices.
According to the study, effects of remote and hybrid work on communications technologies such as computer, phone and internet usage have negligible impacts on overall carbon footprint.
