Prince Charles has embarked from Glasgow’s Central Station on a tour of Britain to promote his sustainable living initiative, START.
Before leaving the station, The Duke of Rothesay tried out a collapsible bike designed for commuters and donated a pair of green cord trousers to a Marks and Spencer and Oxfam stall.
The Prince will travel by the bio-fuel powered Royal Train as he takes his message to communities from Glasgow and Edinburgh to Manchester and London.
Before boarding the Royal train for the first leg of the national tour for his journey to Edinburgh, Prince Charles said: "What I hope to get across, to as many people as possible, is that however awful a predicament we face with climate change and the unsustainable use of the natural resources that keep us all alive, we aren't going to get anywhere by telling everyone what they need to stop doing.
"There's been quite enough of that in recent years and we all know what the reaction is.
"So this week is going to be about the things that we can all start doing for our own benefit, for the benefit of everyone who shares this planet with us and for the benefit of our children and their children too.
"The message of START is about encouraging and assisting everyone to take the first steps towards the world that we all want to live in. A clean, healthy, energy-efficient world that lives within the limits of its natural resources and that we can actually take pride in.
"So START is a simple and positive message. It doesn't lecture or hector anyone about anything, nor does it attempt to frighten you."
Peter Haymes, 32, who is from Carlisle and works with British Cycling, spoke to the Prince about the collapsible bike.
After meeting the royal, he said: "He was asking me how the Brompton bike worked. It is British made. It's an invention for commuters.
"I was very surprised when he sat on the bike. I was pleased that the seat was at the right height for him."
Nancy Gray, 74, from Shettleston in Glasgow, spoke to the Prince as he arrived at Glasgow Central.
"He said, 'I hope I haven't interrupted your day'. I said, 'Welcome to Glasgow and I love you very much'," Ms Gray said.
Asked how she felt to meet Charles, she said: "Overwhelmed."
The Prince also watched a performance by school pupils from Hillhead High School jazz band.
Other stops on the Prince's national tour include Manchester, where he will see students behind a sustainable fashion show, and a team that has launched a beehive scheme in Newcastle.
In Nottingham, the Prince will have a cup of tea with a pensioner who had solar panels fitted in her roof.
The royal tour will then head to Carmarthen, Bristol, Newcastle, Todmorden, Manchester, Nottingham and Birmingham, finishing in London on Friday.
