Kemp, whose earnings amount to more than the London living wage and less than its median salary, is walking the talk already. She’s willing to scrimp a bit more the month before a holiday, for instance for a train trip to Croatia. Not only has this turned her into “a bit of a train geek”, it also taps into a worldwide movement for slower travel. This involves seeing the journey itself as a key part of the experience, where the traveller is forced to be aware of the distance and transitions between locations.

According to Kemp, 10:10 decided to focus on leisure rather than business travel because of the growth of leisure travel (which currently makes up the majority of international travel). Sixteen employers have signed up to Climate Perks so far, including a credit union and an architecture firm, and organisations in Germany, Sweden and the Netherlands. In exchange for pledging to allot at least two low-carbon travel days per employee per year, the companies are given a benefits policy document they’re free to adjust, as well as accreditation and a brand boost.

Could this trend spread?

Glen, the HR and office manager looking forward to skiing in France next year, acknowledges that this might not appeal to a company narrowly focused on the bottom line. “If people aren’t working, then that’s billable time that we wouldn’t be getting. I think the reason that we can go with this is because our main focus is a sustainability aspect.” From a business perspective, she believes it helps her company attract like-minded employees.
