Europe’s largest tour operator said it had reduced the number of brochures produced by 7% in 2017, compared with the previous year and this figure has fallen by two-thirds since 2012.

Two years ago, Tui announced plans to end the production of printed brochures in the UK by 2020 and said this was still an “aim” in its latest sustainability report, Better Holidays Better World.

Tui said it was phasing out traditional brochures and replacing them “with improved digital infrastructure”.

The strategy is part of Tui’s overall aim of cutting carbon emissions from its offices, high street shops and brochures by 20% by 2020, as part of its wider sustainability goals.

Tui’s carbon emissions from its 1,600 shops, including 600 agencies in the UK, totalled 9,694 tonnes in 2017.

The operator introduced energy-monitoring technology across its UK shop network in 2017, which provides energy consumption data for each store.

Another move has seen Tui’s UK cruise brand Marella implementing a range of emissions and environmental management initiatives, including more efficient use of engines and the installation of energy-saving equipment onboard.

One of Tui’s main sustainability strategies is the use of more fuel-efficient aircraft, such as the Boeing 737 MAX, which produces up to 14% less CO2 than older aircraft.

Andrew Flintham, managing director of Tui UK & Ireland, said: “With over 80% of our carbon footprint coming from our aircraft, investing in more efficient planes is key.

“The delivery of 16 new Boeing 737 MAX by end of 2020 in the UK will support the delivery of our commitment to further reduce the carbon intensity of our operations.”
