Prince Harry earned the ire of royal followers after going to a climate change event using a private jet. The Duke of Sussex took a private jet when he attended the Google climate change event recently, causing royal followers to label him as a fake activist and hypocrite.

Since Sicily is a territory far from England, Prince Harry could only go there by boat or by a private jet. When Prince Harry chose to fly via a private jet, royal critics were quick to criticize him. “It doesn’t take a climate change expert to know that when you fly private, it’s not as environmentally friendly as flying commercial, which is basically just extreme carpooling in the sky,” one critic pointed out.

One publication claimed that it was ironic how Prince Harry delivered a speech on environmentalism at the three-day event when he put three tons of carbon into the atmosphere going there. Private jets have 10 times more carbon emissions than commercial flights.

Since the news came out, royal critics have pointed their fingers at the ginger head prince and flooded the social media with negative comments about his move. “Prince Harry just doesn’t get it, does he?” one critic wrote.

“He got invited because he is a Prince faking activism. He wasn’t outraged when Windsor Council removed the homeless so that he can have his wedding! Please! He’s such a joke!” the critic added.

Although private jets are indeed less environmental friendly than commercial planes, members of the royal family traditionally ride private jets instead of taking commercial flights. For a busy man like Prince Harry, travels are usually done at the last minute and with several envoys, so taking a private jet is more ideal.

Other stars who attended the event like Oprah Winfrey, Katy Perry, Orlando Bloom and Bradley Cooper reportedly went to Sicily by boat. The four celebrities were spotted taking rubber boats around the Italian city to the island of Panarea, where they reportedly went swimming and shopping upon their arrival.

According to reports, Google spent at least $20 million on the three-day “Google Camp.” During the event, Prince Harry gave a speech barefoot and declared that he and his wife, Meghan Markle, would have two children at most to help prevent environmental harm.
