In the last few minutes a new draft deal on the key issues, that was negotiated through the night, has been published.

The countries are now going into the final meeting to decide if they want to pass it along with other commitments.

Countries had been at loggerheads over a decision to remove the words "fossil fuels" from previous iterations.

We are going through the new document and will bring you the latest on what it contains - stay with us.

I've just fought my way through a packed crowd of journalists and camera crew into the final plenary, which has limited seating.

The BBC are among those who are set to report on what happens inside the room - stay with us!

The meeting is streamed online, but being inside means we can see what the cameras don't broadcast - body language, facial expressions, and huddles of ministers from countries happy or unhappy about what is being said on stage.

Inside, it's much calmer with a lot of background chatter.

The COP president hasn't arrived yet, and everyone is waiting to see what happens next.

A complex battle at COP30, today we'll see how the fight is shaping uppublished at 14:10 GMT

I’ve been to 15 COPs over the years, but this is by far the most challenging.

It’s featured torrential downpours, steaming temperatures, an attempted break-in as well as a frightening fire.

And that’s before we even get to the highly contentious negotiations.

What’s happening in these talks is something that’s been bubbling up for several years – a bare knuckle fight between those who produce and depend on fossil fuels, and the growing number of countries who want to see an end to the key cause of climate change.

This is no simple struggle between goodies and baddies – this is a complex, nuanced battle that will define how the world powers itself and how our economies will grow in the decades ahead.

It sounds a bit dry – but it is a passionate sometimes bitter struggle, and today here in Belém, we’ll get a good indication of how that fight is shaping up.

These talks were always going to be difficult.

The UK Prime Minister Sir Keir Starmer accepted as much in his speech ahead of COP30. The “consensus is gone” on fighting climate change, he said.

It’s not hard to see why. The US is withdrawing from the Paris climate agreement, which underpins international efforts to tackle rising temperatures.

And in several European countries – including the UK – opposition parties have taken issue with climate policies, arguing they’re adding to the cost of living.

Supporters of COPs highlight that ten years ago, global warming of close to 4C was thought to be on the cards by the end of the century.

Now, current government policies would take us to just below 3C – still way off target, but an improvement.

Part of that is down to economic forces, like the plummeting cost of solar electricity. But the UN says that the Paris agreement has sparked “near-universal” climate action.

And it believes that countries coming together is the best way to secure further progress.

A plenary (final meeting) has been called which means we are nearing the end of COP30.

There are more than 50 different items still to be agreed and we have started to get the new draft texts on those.

The key one we are waiting for is the Mutirão text which contains the commitments (or not) on fossil fuels, finance, trade measures and emissions reporting.

The way the UN climate conferences work is the countries agree by consensus on the deals, there is no voting typically.

Countries will get a chance in the plenary to speak on whether they support or oppose the deal.

If there is consensus then the Brazilians, who are presiding over the talks as the host, will gavel them through.

If they don't agree there may be more informal very last minute talks in the room or it could still fall apart.

But we are nearly 18 hours into overtime. If too many countries have to fly home we lose the critical number required to pass a deal.

So either way we should get a decision today.

All countries present at these annual climate talks have to agree in order to pass a deal.

That can be challenging. Different nations have competing priorities, based for example on their dependence on fossil fuels, economic position or vulnerability to climate change.

As a result, the conference usually overruns, sometimes by more than a day.

But two-thirds of countries signed up to the UN climate convention must be present for decisions to be made, according to UN rules.

And with many delegates due to leave over the coming hours, the clock is ticking for countries to come to an agreement.

I'm crouching down writing this with my laptop on my knees, waiting in a queue of journalists to get into the room where we will find out if the Brazilian president of this COP - André Corrêa do Lago - has secured a deal.

We just saw him in the corridors. He said they worked overnight and finished at 08:20.

"We are opening the final plenary but there will be suspense," he said. The final plenary is where whatever agreement happens at these talks is finalised.

"We got more than we thought we would a year ago," he added.

That's quite a positive spin. Countries here are bitterly divided over how fast to stop fossil fuels and how much finance richer countries should give to developing nations on the forefront of climate change.

Nations have the chance to speak in the plenary - we will see if there are any fireworks.

Good afternoon. COP30 is nearing an end, as delegations are heading into a final meeting - or plenary - where a decision is expected to be made.

Talks were meant to wrap up by 18:00 local time (21:00 GMT) on Friday - and with many delegates already leaving, time is running out to secure a deal.

Host Brazil had hoped countries would agree to set out how to move away from fossil fuels - but a draft deal released on Friday morning failed to mention coal, oil and gas, whose emissions are the main cause of climate change.

As reported by AFP news agency earlier, about 30 countries warned the presidency they will not be able to accept a final deal to this year's climate talks that does not include a plan to move away from fossil fuels.

It comes just days after the COP30 venue had to be evacuated due to a fire breaking out.

We're following the latest at COP30, stay with us.
