Nicola Sturgeon will address young climate activists from around the world ahead of the COP26 summit.
The First Minister will speak to 400 delegates at the launch of the 16th UN Climate Change Conference of Youth (COY) in Glasgow on Thursday.
The COY takes place before the annual UN climate change conference known as COP.
Activists from more than 140 countries will be at this year’s COY.
The First Minister is expected to say “It is only right that you have a say in the decisions which affect you most – that’s a simple matter of fairness – but your presence also gives the summit its very best chance of success.
“Your activism in recent years has spurred on, challenged, and inspired governments around the world.
“I can honestly say that you are the reason why, in 2019, Scotland became one of the first countries to declare a climate emergency.”
She will say: “The idealism, creativity and sense of perspective that young people bring to this issue is a huge asset and I think it will help to ensure a successful outcome to Cop.
“You should not have had to become the conscience of decision-makers around the world, but we will reach a better outcome if you are.
“We are determined that your voices will be heard.”
