Return to office vs remote work: the real carbon footprint comparison

A new analysis from Canada's National Observer digs into the environmental impact of mandated return-to-office policies, particularly the Canadian federal government's four-day in-person requirement. The article goes beyond simple commute math and looks at rebound effects like remote workers living farther from cities, owning more cars, and making more personal trips. Researchers found that when you account for all factors, the difference between remote and in-office work is only about 10 percent in total carbon footprint. The piece cites a study of 364 employees at INRS showing remote work avoided just 0.08 tonnes of CO2 per person annually, or 0.88 percent of the average Quebecer's emissions. Office building energy use matters a lot less if companies keep lights and HVAC running regardless of occupancy. The article is worth reading for anyone in climate policy or corporate sustainability who needs to move past the obvious commuting argument and understand the full system effects of work location decisions.
