We believe first and foremost that people need to cut down on unnecessary travel to reduce their contribution to global warming. However we recognise that some business travel is necessary and individual travel can be highly desirable. Therefore we view carbon-offsetting as a positive step to repair negative impacts on the climate.

• The Guardian, The Observer and Guardian Unlimited offset all business air travel booked via a central travel agent

• All travel journalists' flights taken to produce articles for Guardian Travel, Observer Escape and Guardian Unlimited Travel are also offset via ClimateCare and non-flying holidays are promoted editorially

• Reader flight offers from our marketing department provide an option to offset emissions

Offset your emissions

We have joined forces with ClimateCare to help you calculate your share of emissions from flights, car journeys and household utilities. Paying to offset your emissions costs less than you might think and the money will be used to fund projects which absorb, reduce or avoid an equivalent amount of greenhouse gases elsewhere.
