Prince Charles has been accused of talking the talk but not walking the walk after flying more than 100 miles in a private helicopter to make a speech about lowering aircraft emissions.

The royal flew 125 miles from Highgrove to Cambridge to speak to scientists from Cambridge University’s Whittle Laboratory, who are leading research into the decarbonisation of air travel.

It is estimated that his total journey of 368 miles cost at least £12,000 and caused about 2.5 tonnes of carbon emissions, the Mirror reports.

In a statement, Clarence House defended the 71-year-old royal, saying the carbon footprint left by his travels are was offset every year.




‘The prince is not personally involved in decisions around his transportation arrangements, though he ensures all carbon emissions are offset every year,’ a spokesperson said.

‘They are made based on what is possible within the constraints of time, distance and security.

‘In order for him to undertake as many engagements as he does across the UK and around the world he sometimes has to fly. As he has often said, as soon as there is a more sustainable way of making these journeys, he’ll be the first to use it.’

It is estimated that Charles could have cut his emissions down to just 0.2 tonnes if he had travelled by car.

Campaign group Republic’s chief executive Graham Smith told the Mirror: ‘He wants to play the role, but not walk the walk.

‘His view seems to be that it’s one rule for him and one rule for the rest of us.

‘Driving or using the train would have been pretty easy.’

The royal recently faced criticism for flying 16,000 miles in private jets and helicopters in the days leading up to this year’s World Economic Forum in Davos, Switzerland.
