Prince Charles demanded global green taxes as part of a radical push to tackle climate change in a seminal speech at Davos today.

The Prince of Wales met Greta Thunberg at the Word Economic Forum after flying in to Switzerland on a private jet – but did not hold talks with Donald Trump.

Charles even sounded like the 17-year-old Swedish activist as he asked VIPs: ‘Do we want to go down in history as the people who didn’t do anything to bring the world back from the brink? The only limit is our willingness to act and the time to act is now’.
