If billions of people worked just one day a week from home, the reduction in commuting emissions alone would be transformative. Two days a week and numbers quickly start to show the change. Three days a week and it goes beyond transport. Quieter roads all week, less infrastructure needed, and something more profound, people no longer having to live where they work.
We are not talking about an exodus to the countryside. But the sustainability benefits of the theory of Urban Decentralisation are well documented. If you work in the city two days a week, you can live outside it, you can have space, a garden, a slower pace. And as a result big cities get less pressure on their roads and their infrastructure. Cities are extraordinarily expensive to run at peak density, every additional person requires water, sewage, transport and waste systems built at enormous cost into ground that’s already full. Every day, thousands of lorries bring food, goods and supplies in, and others take waste back out.
Even modest dispersal compounds across millions of people into something genuinely significant. Less construction. Less energy consumption. Shorter supply chains. More green space per person. The sustainability case for hybrid working goes much deeper than fewer cars on the road.
