Billboards calling out Prince Charles and Prince William as 'climate change hypocrites' will be going up in Glasgow and around the UK next week.

Campaign group Republic has said the cause of tackling climate change is being harmed by royal hypocrisy.

The billboards point out that Prince Charles and Prince William use helicopters and private jets while maintaining multiple huge homes, all at a huge cost to the environment.

Graham Smith, speaking for Republic, said today:

"With COP26 approaching the royals have been busy lecturing everyone on the need for action on climate change. The hypocrisy is breathtaking."

"Senior royals routinely make use of helicopters instead of cars and fly longer distances by private jet. And they all maintain multiple large houses that will have an enormous carbon foot-print."

"The royals need to be challenged on their 'do as we say' attitude."

"In November, during the COP26 climate change conference Republic will be putting up billboards in Glasgow and around the UK, calling out the princes for their hypocrisy."

"There is no excuse for Prince Charles to fly everywhere by helicopter, or for William to take private jets when he could go by train or scheduled flight."

"And the royals do not need multiple palatial homes. If they want to lecture on climate change they need to start leading by example."

"The royals are clearly worried about what happens after the Queen dies. This is more PR to bolster their credibility and it must be called out for what it is: cynical and hypocritical."

The billboards are part of a wider campaign that began in August, featuring a range of designs around the UK.
