Scottish First Minister Nicola Sturgeon has declared a “climate emergency” in her speech to the SNP conference.
The SNP leader told delegates in Edinburgh she was inspired after meeting young climate campaigners who had gone on strike from school.
She said “they are right”, and pledged that Scotland will “live up to our responsibility” to halt climate change.
Labour is expected to press the UK government to declare a national climate emergency on Wednesday.
The party will call for a dramatic cut in the UK’s carbon emissions, with leader Jeremy Corbyn also calling for a UK-wide ban on fracking.
Fracking has already been halted in Scotland by Ms Sturgeon’s devolved government.
It comes after weeks of strikes by school pupils and protests by Extinction Rebellion protestors, which have targeted both the UK and Scottish parliaments.
Ms Sturgeon told the conference that Scotland is a “world leader” on climate change, and is already committed to being carbon neutral by 2050.
But she pledged that it would continue to “lead by example” as our obligations to the next generation are “the most important we carry”.
The first minister said: “A few weeks ago, I met some of the young climate change campaigners who’ve gone on strike from school to raise awareness of their cause.
“They want governments around the world to declare a climate emergency. They say that’s what the science tells us. And they are right.
“So today, as first minister of Scotland, I am declaring that there is a climate emergency. And Scotland will live up to our responsibility to tackle it.”
The Committee on Climate Change is due to publish new scientific advice on Scotland’s emissions targets this week.
And Ms Sturgeon made clear that “if that advice says we can go further or go faster, we will do so”.
SNP MSPs – along with those from the Tories, Labour and the Lib Dems – voted down a Scottish Parliament motion put forward by the Greens calling for a “climate emergency” to be declared on 27 March, after disputing the impact of the oil and gas industry.
Energy Minister Paul Wheelhouse said in that debate that climate change was an “urgent” matter, but that the government a duty to respond “responsibly” and “keep Scotland’s lights on”.
Ms Sturgeon’s conference speech came just days after she announced that she wants a second referendum on Scottish independence by 2021 if the UK leaves the UK.
The UK government has already said it will not grant the permission that Ms Sturgeon says is needed before a referendum is actually held.
But she told party members that a “surge” in support for Scottish independence could force the UK government to change its stance.
Ms Sturgeon said that rise in support would demonstrate that “no Westminster government can ever stand in the way of Scotland’s right to choose”.
She also revealed Scottish Parliament legislation that could pave the way for a referendum would introduced in May.
The aim would be to pass it by the end of the year, she said, so that it is in place should the UK government ultimately agree to a referendum being held.
The first minister also described how her plans for a Citizens’ Assembly would allow people from across Scotland to “guide the conversation” about independence.
