Scottish Greens co-leader Lorna Slater has said the oil and gas industry must transition to suit a greener economy, or face being wiped out.

Speaking at the Scottish Green Party conference in Inverness, Slater said oil companies will have to switch their focus to renewable energy to solve the climate crisis.

She said: "The option is transition or die, and that's not me saying that, the planet is saying that.

"You can't argue with the physics and chemistry of planetary geo-science.

"You must transition or die, we all must transition or die.

"If we get to six degrees of global warming, which we are on track to do if we don't make changes, 95% of life on earth will be extinct.

"There's a reason people like Extinction Rebellion are using that type of language.

"Transition is possible, you can transition a whole industry if you plan for it.

"We've got ten years, the problem is if you delay starting then you only have eight years, then you only have six.

"You can get a lot done in ten years, but you have to start now."

Slater, who works as an engineer for tidal turbine firm Orbital Marine Power, also said that if companies are worried about profits, there is money to be made in the renewables sector.

She said: "We have just raised an £8 million contract with Texo in Dundee to build one of our turbines.

"They are a company who have traditionally worked in oil and gas and now they're transitioning to renewables. It can be done.

"Us and our competitors have shown that you can generate power from the tide and that you can generate money from the tide.

"It's just one turbine, which is going to keep Texo busy for most of next year.

"What if it was five or ten or twenty?

"There is absolutely an industry out there, there is work in renewables.

"We have 25% of Europe's renewable energy, we don't need oil and gas, we can get rich from renewables.

"If getting rich is what you want, then we've got what we need to make people rich."

At the conference the party continued its push for a Green New Deal, a broad-ranging set of policies to create a more environmentally friendly economy in Scotland, which the Greens say will also create thousands of jobs.
