Leaders from across the world will descend on Scotland's biggest city in an effort to tackle the climate crisis.

And from road closures to looming protests, if Glaswegians didn’t know about COP26 before, they will now.

The SEC is now part of the Blue Zone

As part of preparations for the summit, Glasgow’s Scottish Events Campus (SEC) has officially been handed over to the United Nations (UN) for the duration of the event.

As part of the Blue Zone, the area where world leaders will try to hash out climate negotiations, the venue will be official UN territory for the duration of the summit.

It will run from October 31 until November 12.

But what does it mean now parts of Glasgow are now international territory?

It means armed UN officers will patrol the events campus which will be under the highest levels of security as it welcomes major world leaders including American president Joe Biden and French president Emmanuel Macron.

Police Scotland will not be allowed to enter the blue zone, which includes the Scottish Exhibition Centre, the SSE Hydro Arena and the SEC Armadillo, unless they are invited by UN secretary-general Antonio Guterres or if they believe there is a threat to life.

What if a crime is committed at the SEC?

The area will remain under the jurisdiction of Scots Law in the event that any crimes are committed.

However, inside the blue zone UN officials, representatives and experts all have diplomatic immunity meaning they are exempt from the legal process.

What will the security be like?

Tight. Organisations sending delegates to the historic climate summit had to register a year ago, facing tough restrictions.

And some 10,000 police officers are expected to patrol the area around the SEC.

Forces around the UK will assist Police Scotland, who is in charge of the operation, which will account for 45% of the officers there.

As well as that, the Ministry of Defence (MoD), police divers, the Civil Nuclear Constabulary and the British Transport Police will all help to ensure world leaders and delegates are safe.

The MoD has also confirmed there will be a 24/7 armed police presence on the river.

What about the green zone?

The green zone will primarily focus on the Science Centre, south of the River Clyde, and will host a series of ticketed events.

It aims to showcase the inspiring stories and advances being made to tackle the climate crisis.

The green zone is managed by the UK Government and will not fall under UN authority.

It’s a platform for the general public, activists, groups and others who want to have their voices heard.
