Prince Harry has been travelling by private jet to keep his family "safe" but admitted he could "do better".
The 34-year-old royal - who has four-month-old son Archie with wife Duchess Meghan - has come under fire recently for taking four private planes this summer despite his outspoken attitude towards climate change but he has now defended the decision and admitted he could "do better".
Speaking in Amsterdam on Tuesday - where he was launching the Sussex Royal Foundation's new initiative Travalyst - he said: "We can all do better. And while no is perfect, we are all responsible for our individual impact. The question is what we do to balance it out.
"I came here by commercial. I spend 99 percent of my life traveling the world by commercial. Occasionally, there needs to be an opportunity based on a unique circumstance to ensure my family are safe and it's genuinely as simple as that. But as I said in my speech, for me, it's about balance."
Harry also joked about the positives of travelling without his wife and son.
