People Who Work From Home All The Time ‘Cut Emissions By 54%’ Against Those In Office, Report Says

A recent study reveals that individuals who work remotely full-time contribute less than half the greenhouse gas emissions of their office-bound counterparts.

The study, conducted by researchers from Cornell University and Microsoft, employed multiple datasets, including Microsoft’s own employee data, to model the projected greenhouse gas emissions of office workers, remote workers, and hybrid workers in the U.S. The analysis encompassed five emission categories: energy consumption within offices and residences.

The findings indicated that remote work’s significant reduction in emissions primarily results from decreased office energy usage and a decline in emissions associated with daily commuting. Full-time remote workers achieved a remarkable 54% reduction in emissions compared to their office counterparts.

However, for individuals who engaged in just one day of remote work per week, the emissions reduction was a mere 2%. This modest impact occurred because energy savings from not being in the office were offset by factors like increased non-commuting travel when working from home. Those who opted for two or four remote workdays a week enjoyed emissions reductions of up to 29% compared to on-site workers.

Interestingly, the study emphasized that IT and communications technology had minimal influence on individuals’ carbon footprints related to work. Instead, the primary drivers of reduced emissions for remote workers were lower office energy consumption and a decrease in daily commuting emissions.

While the benefits of working from home extend beyond emissions reduction to include alleviating vehicle congestion during rush hours and potential fuel economy improvements, the researchers cautioned that remote work needs careful planning to maximize its environmental advantages. They noted that some remote workers increased non-work-related travel, leading to more driving and flying, which could offset emission savings.

Fengqi You, co-author of the study from Cornell University, dispelled the notion that remote work automatically equates to being “net zero” in emissions, emphasizing that the net benefit is positive but varies. Moreover, the study highlighted that homes may not always be optimized for emissions reduction in terms of renewable energy usage and appliance efficiency. Additionally, certain small-scale appliances at home might be less energy-efficient than their office counterparts.

The COVID-19 pandemic prompted a remote working revolution, with many office workers relocating from densely populated commuting zones to more rural areas. While this shift may result in longer commutes for hybrid workers and increased use of private vehicles, it underscores the importance of examining commuting patterns, building energy consumption, vehicle ownership, and non-commute-related travel to fully realize the environmental benefits of remote work.

While the study’s findings pertain primarily to the United States, the researchers believe that similar trends and modeling would apply in Europe and Japan. They call upon companies to focus on energy-efficient measures, consider downsizing, and explore shared office spaces as means to reduce emissions and energy consumption.

The study’s findings are published in the Proceedings of the National Academy of Sciences.
