With each worker's carbon footprint being between 1.5 to four tonnes per person, working from home will help the environment and reduce congestion, said the RAC Foundation.

It found that working from home can reduce energy usage by up to 80%, and that two-thirds of an office worker's energy consumption is spent on transport.

“The energy and cost savings of working from home are very impressive.

"If everyone who was able to, worked from home just one day a week, we would notice a big difference on our roads and our other already overloaded infrastructure,” said Sheila Rainger, deputy director for the RAC Foundation.
