Four-day week would dramatically reduce UK’s carbon footprint

World’s largest trial finds four-day week reaps environmental and health benefits.

Trial suggests that 91% of organisations will continue with a four-day week as employees are happier, less tired, and adopt more pro-environmental behaviours

A four-day working week with no loss of pay could reduce the UK’s carbon emissions by 127 million tonnes – the equivalent of removing the UK’s entire private car fleet from the road - and could help the country meet its binding climate targets.

The world’s largest trial into a reduced working week involved over 60 companies and almost 3,000 workers; it found a four-day week could reduce commuting time by around half an hour per week and slash energy usage in the workplace.

“While definitive estimates of carbon impacts are nearly impossible to put together, we do see encouraging trends on a number of dimensions in our trials: reduced commuting time, reduced commuting by car, people reporting more pro-environmental behaviours over the course of the trial, and absence of a significant travel rebound. These vary a bit across the completed trials but not by a lot,” said Juliet Schor, an economist and sociologist at Boston College and lead researcher at 4 Day Week Global.

Environmental consultancy, Tyler Grange participated in the six-month trial; they reported a daily productivity increase of 22%, and a 21% reduction in the number of miles travelled by car by cutting out unnecessary meetings and travel.
