Fly less

Taking a flight will dwarf all other elements of your holiday in terms of carbon emissions. Use sites such as carbonresponsible.com to calculate the footprint of a particular journey and see how long it would take you to make the equivalent carbon saving by cutting down on car journeys or using low-energy lightbulbs. Sites such as seat61.com and sailanddrive.com help you plan breaks by rail and ferry as alternatives to short-haul flights.

Find green accommodation

There are more than 20 ‘green’ accreditation schemes in the UK and more than 100 worldwide. Look out when choosing a holiday for members of the Green Tourism Business Scheme (green-business.co.uk); Legambiente in Italy (legambienteturismo.it); the Certificate in Sustainable Tourism in central America; and Australia’s Ecotourism Certification programme (ecotourism.org.au). The greener hotels in package holiday brochures should now display the ‘Travelife’ logo.

Find a green tour operator

The Association of Independent Tour Operators (aito.co.uk) has a rating scheme for members. If you decide to book directly and bypass tour operators, charity Tourism Concern (tourismconcern.co.uk) has 300 vetted community-run trips on its website.
