It is the latest step in the Barcelona firm’s ongoing efforts to bolster its sustainability credentials and that of the wider travel industry, with Susterra set up to help businesses cut their environmental footprint.

Back in July, the company took over business travel outfit Click Travel, a multiple-times TTG Top 50 Top Travel Agencies award winning agency.

Susterra, founded by environmental scientist James Dent, uses data analytics technology to offer companies an overview of their business travel-related environmental impact.

Its reports, which cover air travel, hotels, car hire and rail travel, help businesses understand how to improve their carbon efficiency, reduce costs and achieve sustainability goals.

The technology will be integrated into TravelPerk’s platforms in the coming months.

Ross McNairn, chief product officer of TravelPerk, reported a "massive demand" from clients for future in-person meetings to have the lowest possible impact on the environment. 

"The meetings that matter will always happen in person so companies will always need their employees to travel in order to meet customers, prospects and teams face-to-face," he added.

"It’s for this reason that we are investing heavily in helping our clients get a true representation of their footprint so that they can consciously take mitigating action both through TravelPerk and their own programs.

"Sustainability is a long game and we want to be leaders in this transition."
