Prince Charles attended the World Economic Forum (WEF) in Davos, Switzerland last week, where he outlined an initiative for rapid decarbonization and sustainable markets, and met teen activsit Greta Thunberg.

Before Prince Charles met with Thunberg, he took three private jets and one helicopter for government business, according to the Daily Mail. His flights totaled over 16,000 miles in just 11 days.

But he traveled in an electric Jaguar car for the journey from the airport to the Swiss ski resort. We have to give him credit for that.

The Prince of Wales urged world leaders to make a “bold and imaginative action” in his address at WEF and declared “climate change, and the devastating loss of biodiversity are the greatest threats humanity has ever faced and one largely of our own creation.”

He urged over 3,000 business leaders and politicians to help the private sector lead ‘the world out of the approaching catastrophe.” He then asked the audience whether or not they want to “go down in history as the people who did nothing to bring the world back from the brink, in trying to restore the balance, when we could have done?”

“I’ve dedicated much of my life of the restoration of harmony between humanity, nature, and the environment and to the encouragement of corporate social and environmental responsibility,” Prince Charles told the crowd. “Quite frankly it has been a bit of an uphill struggle,” he added.

According to the Paramount Business Jet calculator, the estimated 16,000 miles – 3 private jets and helicopter and the five “empty-leg” flights – emitted over 162 metric tons of carbon. That’s 18 times more than a Briton’s yearly total!

After Davos, Prince Charles took another private jet flight to Israel.

Prince Charles, the lifelong environmentalist, told CNN’s Max Foster, “I’ve always worried about the fact that so often, in terms of humanity, we leave everything too late.”
