Dutch travel firms are to start informing holidaymakers how much environmental damage their trip is doing by listing ‘holiday footprints’ in brochures and on websites, travel sector organisation ANVR says in Tuesday’s Volkskrant.

‘We aim to eventually allow consumers to calculate their own holiday footprint via an app or website,’ ANVR spokesman Gerben Hardeman told the paper. ‘We are still a long way off that. But we are now working with a group of travel firms to determine how we can best inform consumers about what we know already.’

By helping consumers to realise the impact of their holiday on the environment, holidaymakers can ‘make a responsible choice’, he said.

Currently, airline passengers can pay extra to offset the cost to the climate of their journey. The amounts vary from €10 to €100, depending on the way the potential damage is calculated by different airlines.

The system used by the ANVR has been developed by researchers at several hbo colleges and 10 travel firms. It is based on confidential information from airline manufacturers, airlines themselves and the hotel website Bookdifferent.com.
