Allyson Chiu writes in the Washington Post about “How a four-day workweek could be better for the climate:”

Reducing the workweek to four days could have a climate benefit, advocates say. In addition to improving the well-being of workers, they say slashing working hours may reduce carbon emissions….

Over the years, studies have documented a link between fewer working hours and lower emissions — reductions that experts explain may be the result of changes to commuting, energy use and lifestyle habits. One analysis of data looking at more than two dozen countries from 1970 to 2007 predicted that if work hours were reduced by 10 percent, there could be drops in ecological footprint, carbon footprint and carbon dioxide emissions by 12.1 percent, 14.6 percent and 4.2 percent, respectively.
