The Paris Climate Agreement Glasgow Five years on perhaps the last chance to implement that agreement at the Conference of Parties Climate Talks Cult here in November.

Today the UK was due to launch its cop vision in London.

Extinction rebellion outside the green great and good inside, waiting to hear an announcement about cars as part of that vision.

Tailed overnight by Downing Street in the hurricanes and the bush fires and the melting of the ice caps and the acidification of the oceans, the evidence is now overwhelming, but they're waas no announcement on cars indeed, no concrete policy or action announced at all.

You have to look on the government website to see they plan to ban sales of new diesel, petrol and hybrid cars by 2035.

Now, not 2040.

I think it would take something like a cutting the tea on new electric vehicles on the inclusion of hybrid vehicles to really make it work.

Without those incentives, thes targets are a massive challenge.

Before the prime minister even took the stage this morning, things were already off to a bad start with this Claire O'Neill avenging Boris Johnson for sacking her as president of Cop 26 this year's vital climate conference just nine months away, now in Glasgow.

He's also admitted to me that he doesn't really understand it, and it's good, really.

He said that, you know, he gets I mean, he's had all sorts of things over the years, but he doesn't understand climate.

He doesn't.

He doesn't really get it.

I think is what he said.

We have others around him do.

She wasn't done publishing her letter to the prime minister.

There's a yawning gap between what the world expects from us and where we are.

It's a systemic failure of global vision and leadership.

On this, we're miles off track.

You promised to lead from the front and asked me what was needed.

Money.

People just tell us.

Sadly, thes promises in office are not close to being met.

A very public spat, a looming conference in Glasgow, builders, our best chance to save the world as we know it, and no leader in place on foreign diplomats who were here today say that really matters.

The world really needs and urgently clear leadership as we move towards that conference.

Note this from a key architect of the Paris climate agreement.

Didn't develop the policy elements or particular views on the geopolitics off climate change.

It was basically to say We can make it way have to bring all countries together, showing that you can do it and can deliver So it was sort of more domestic message.

The enveloping sense of shambles topped off today by Downing Street trying to ban journalists from asking questions.

Next lesson.

One for the Italian prime minister.

Great.

What's your plan?

Prime Minister Wanted you sacked Claire O'Neill?

No.

When are you going to name her successor when you're gonna name her, but no answers.

He was there to issuing another of his final final final warnings of why the cop conference matters.

This is now up to us to put before the nations of the world what has to be done.

We don't need to emphasize to them or to you that the longer we lead it of not doing things but going on talking about the problems the West it's going to get.

Thus the U.

K's presidency of the Glasgow Cop Conference is now launched, but there's no captain on the bridge and it feels rudderless.

Alex Thompson reporting on our staying with climate change The U.

K's aviation industry has announced plans to reduce its net carbon emissions to zero by 2050.

It says it will do so through plena bar fuels and electric planes, rather than reducing the number of flights well.

Earlier, I spoke to the chief executive Heathrow Airport, John Holland K R.

Background, asking him whether, given the concern expressed by some environmentalists about bio fuels, the airline industry should be relying on them to make itself carbon neutral.

Well, no one needs to cut down any rainforest to keep planes flying.

This is about sustainable aviation fuel, so energy from second generation biofuels from forestry, agriculture and domestic waste on synthetic fuels, which are made from combining carbon monoxide and hydrogen that both technologies that exist today.

They are both sub scale, but they can be scaled up on what we need now is significant investment and supporting government to make sure that scaling up happens just as we had with solar and offshore wind, which has transformed the availability and cost or sustainable energy in other sectors.

Let's take just one of the options that you've mentioned electric flying.

The fact is, there's not a plane in the sky yet that is practicing this usage of fuel.

There are electric planes that exist today.

We tend to think of them as being the kind of copters that will take one or two people up.

That is electric flight.

But you're what we are talking about here is a significant scaling up off of short haul, flight battery powered Onda.

We don't see this as being a huge part of the solution by 2050 but it will be part of the solution on the UK government has a fantastic opportunity Cop 26 to champion a UK solution to a global problem, which is D carbon izing flight on.

We really need todo no mention.

One obvious obvious solution, which is to fly less flying less will not stop people fly in China or India on In fact, 11 issue that I often get asked about is is about the expansion of Heathrow now.

Expansion of Heathrow was stopped 10 years ago by the coalition government with the intention off off limiting climate change.

What was the result of that?

More people flew from Britain to Amsterdam to Paris on, then took another flight to get to global destinations.

Not a single ounce of carbon was saved by not expanding Heathrow.

What we do have is ridiculously cheap flights.

We do have far too much flying and you won't accept any of that.

You just think we can go on as we are, but we'll just find another way of doing it.

I aviation is a fantastic thing.

It is a blessing for this world that we can now go to other parts of the world, meet other cultures that we can trade, which is a big part of what aviation is about.

So we should be proud that we're coming up with a real solution to a really world issue, not just telling people they can't fly, but coming up with a real practical solution.
