This week Harry hit back at critics following the mass public outcry over their private jet use.
On Monday, the Duke of Sussex made his way to the Netherlands where he announced the Sussex household will partner with online travel firms that aim to transform the aviation and travel industry into being more environmentally friendly.
At the event, the vocal climate change warrior addressed his recent use of a private jet after the scandal caused A-listers such as Elton John, Ellen DeGeneres and Pink to jump to the defence of the Royal couple.
"No-one is perfect," Harry said of the incident.
Prince Harry and Meghan Markle chose to fly on a private jet rather than commercial flights - the latter option being frequently used by Prince William and Kate Middleton as of late - despite the couple speaking out on environmental issues.
For his most recent journey to the Netherlands, the Royal took a commercial flight.
