Prince Charles arrived in Glasgow ahead of his opening speech at UN Climate Change Conference.
As COP26 began, the Duke of Cornwall was carrying a large folder and posed with Camilla.
MailOnline revealed that he was among those who flew non-commercially from Rome to the G20.
A source claimed that he would only have agreed to travel if he was sure the aircraft was using sustainable fuel.
Boris Johnson will be joined by the Prince of Wales who will address leaders. He is expected to stress the need for action and call for a world on a war-like footing.
The Royal will warn us: “We must put ourselves on what might have been called a warfare-like footing.”
He will encourage world leaders to work with business to address the climate crisis.
Charles will add, “We need a massive military-style campaign with trillions of dollars to marshal the strength and power of the global private sector.”

The Prince of Wales met last night with Jeff Bezos (billionaire Amazon boss) and Lauren Sanchez (girlfriend).
The trio was seen enjoying a cup at Dumfries House in Scotland, 40 minutes from Glasgow, in a photo shared by Bezos’s social media.
Ms Sanchez and Mr Bezos sat on blue Chippendale armchairs. They were surrounded in Resplendent Blue Drawing room portraits.
The Amazon boss smiled as the heir gestured towards a cup of tea, perched on a table. Ms Sanchez leans forward, intently listening.
Bezos wrote: ‘The Prince of Wales has been involved in fighting climate change and protecting our beautiful world for five decades — far longer than most.
‘We had a chance to discuss these important issues on the eve of #COP26 — looking for solutions to heal our world, and how the @BezosEarthFund can help.’
