The adventure travel company has been paying carbon credits to offset all its activity since 1 January this year and believes it is the first UK-based tour operator to do so.
All the money is being channelled into Gold Standard projects provided by ClimateCare.
Explore has used a worst-case scenario to calculate the carbon emission for each trip – the furthest airport in each region and indirect flights.
Trip prices now include the extra cash needed to carbon offset.
