Lego, fossil fuels and the COP28 climate deal: What toy bricks tell us about the immense difficulties of going green
The last-minute deal agreed at the COP28 summit in Dubai to move away from fossil fuels is being heralded as a major breakthrough.
But while it’s the first time these annual climate negotiations have agreed to reduce our reliance on coal, oil and gas, it stops short of what many campaigners had been demanding: a promise to phase out fossil fuel use altogether.
Which raises a question: Why?
Why couldn’t the meeting go one step further and promise to leave all fossil fuels in the ground?

Applause for ‘historic’ COP28 deal
Perhaps the best answer begins somewhere unexpected: with a piece of Lego.
Most Lego bricks are made of a plastic called Acrylonitrile Butadiene Styrene, or ABS for short. It’s a tough thermoplastic, which is to say one of those plastics you can melt down and form back into other shapes again, and it’s brilliant at doing all the things Lego bricks need to do.
It’s incredibly durable. It can be moulded precisely, with tolerances of within four microns, meaning one brick fits neatly into another.
Finally, it has pretty unbeatable “clutch power”, as the company calls it: the bricks stick together robustly but are also pretty easy to pull apart.
But ABS is made, like nearly all plastics, out of chemicals derived from oil and gas.
A few years ago Lego committed to trying to make its blocks not directly from oil but from other feedstocks.
After much investigation it experimented with using old plastic bottles – or recycled polyethylene terephthalate (RPET), to use the technical term.
But, try as it might, it struggled to make this RPET work as well as ABS. The only way to make it perform as well as the old brick – the rigidity, the accuracy, the “clutch” – was to process it and reprocess it, adding a host of additional materials along the way.
A few months ago, it revealed that in practical terms those efforts – thus far – had failed. Ironically enough, it took more energy to turn those recycled bottles into bricks than it did to take oil and turn it into bricks.
Fossil fuels are hard to beat
Now, it’s still relatively early days. But Lego’s efforts are a pretty good reminder of something pretty profound. Like it or not, fossil fuels are remarkably good at what they do.
We use them in vast quantities because they are a brilliant source of energy and a brilliant source of chemicals.
Coal, demonised as it may be these days, isn’t just good at firing up power stations; it’s also nearly unbeatable (in its coked form) at helping you turn certain ores into metals.
The good news – from a carbon cutting perspective – is that we’re getting better and better at finding alternatives to most of the things fossil fuels do.
Electric cars are in many ways better than the petrol cars they’re replacing. Wind and solar panels are very good at generating electricity – though we’re still working on reliable, affordable and green ways to back up the grid when the wind’s not blowing.
But for certain purposes – purposes far more serious than some toy building blocks – it’s still very hard to beat fossil fuels.
We still rely on natural gas for most of the world’s nitrogen fertiliser production, without which half of the world would starve.
We still have yet to find a way of mass producing concrete without spewing a lot of carbon dioxide into the air. And making plastics without oil is, as Lego learnt to its cost, tricky, to say the least.

Now, there are very smart people working on all of the above and there are really promising green candidates for many of these tricky fossil fuel products.
But many remain at the prototype stage, a very long way from being able to compete on a level playing field with their industrial counterparts.
The upshot is that even the most ambitious plans for how we might reduce global carbon emissions still assume we’ll be using fossil fuels come 2050 – and potentially into the foreseeable future beyond that too.
Even optimistic plans admit we’ll need some fossil fuels
Take the International Energy Agency (IEA) Net Zero by 2050 plan.
This framework has all the green credentials – indeed it’s often cited approvingly by organisations like Just Stop Oil, since its models suggest there’s no need for further oil and gas exploration.
But even this plan still assumes we’ll be getting more than a fifth of our energy from fossil fuels (mostly oil and gas) come 2050.
Now it’s worth saying, about a third of those 2050-vintage fossil fuels are not being burnt, but are instead being turned into products like plastics (including Lego bricks, if they haven’t cracked it by then).
Which is an important distinction because they won’t be responsible for the carbon emissions we’re really concerned with.
But that still leaves a lot of fossil fuels being burnt – a lot of them in the engines of planes (sustainable aviation fuel will only get us so far, thinks the IEA) and some to do all those other tricky things like making fertilisers and so on.
And here’s the key thing, the thing one can’t emphasise enough: this is not a conservative plan. This is about the most optimistic plan you’ll find among policymakers today (that doesn’t involve drastic changes in living standards).
But even this plan for net zero depends on a large chunk of fossil fuels being burnt.
Some of the emissions, reckons the IEA, can be captured and squirrelled away underground (“carbon capture and storage” or CCS as it’s called) – though it’s worth saying CCS is one of those technologies that’s still barely been carried out at large scale.
But even after you subtract that, there’s still a not unsubstantial amount of unabated fossil fuel burning going on.
Even in 2050. Even in the most optimistic of all likely pathways.
And here’s the other thing you need to know. We’re already falling far short of that pathway.
Right now our oil production is way, way above where that IEA pathway said it should be.
Reasons for hope
Global carbon emissions are now so far beyond where they should be heading if we wanted to keep global warming below the 1.5C threshold most campaigners are pushing for.
Indeed, a glance at the statistics suggests that that goal is now incredibly unlikely – some would say impossible.
Yet for all of this, there’s plenty of reasons for hope.
Overall emissions may be higher than we’d like them to be, but by the same token they’re considerably lower than they seemed to be heading back in 2015.

Carbon emissions: The global picture
Thanks to technologies like wind turbines, batteries and solar panels, the world is getting better at generating clean energy quicker than expected.
The very scariest climate outcomes look much less likely today than they did a few years ago – according to the IPCC’s own analysis.
But the more we wrestle with the difficulties of the energy transition, the clearer it is how enormous the challenge ahead remains. And a forensic look at that challenge underlines why there’s a very big difference between pledging to “phase down” and to “phase OUT” fossil fuels.
The former is doable – and it’s pretty extraordinary it’s taken this long for COP ministers to commit to it.
Achieving the latter by 2050 while maintaining today’s levels of living standards is close to inconceivable.
Israeli Prime Minister Benjamin Netanyahu will be meeting Donald Trump next Monday, according to US officials.
The visit on 7 July comes after Mr Trump suggested it was possible a ceasefire in Gaza could be reached within a week.
On Sunday, he wrote on social media: “MAKE THE DEAL IN GAZA. GET THE HOSTAGES BACK!!!”

According to the Hamas-run health ministry, 56,500 people have been killed in the 20-month war.
The visit by Mr Netanyahu to Washington has not been formally announced and the officials who said it would be going ahead spoke on condition of anonymity.
An Israeli official in Washington also confirmed the meeting next Monday.
White House Press Secretary Karoline Leavitt said the administration was in constant communication with the Israeli government.
She said Mr Trump viewed ending the war in Gaza and returning remaining hostages held by Hamas as a top priority.

The war in Gaza broke out in retaliation for Hamas’ 7 October 2023 attacks on southern Israel that killed 1,200 people and saw a further 250 taken hostage.
An eight-week ceasefire was reached in the final days of Joe Biden’s US presidency, but Israel resumed the war in March after trying to get Hamas to accept new terms on next steps.
Talks between Israel and Hamas have stalled over whether the war should end as part of any ceasefire.

Brutal murder on ‘date’ exposes robbery gang suspected of targeting dozens of women in South Africa
Thirty-year-old Olorato Mongale made sure to take all the measures necessary for a safe first date in South Africa’s biggest city, Johannesburg.
She had agreed to meet ‘John’ in the daytime. She sent her friends her phone location after leaving her house and promptly texted them “on the road” at 2.47pm.
They replied “enjoy!”, hoping she would find love.
An hour later, their friend had gone silent and her phone location was showing up in dangerous areas of the city.
A search party of seven friends set off to trace Olorato’s digital footsteps.
It’s believed Olorato’s killers were part of a gang robbing young women at gunpoint
“It didn’t make sense. Where is she? Why is she missing?” says Karabo Mokoena, as we drove to the locations involved in their search.
“Every place we went to looked dodgier and dodgier. It made me panic – I was very scared.”
After finding her bag on a pile of bricks off the side of a main road, they filed a missing person report at a police station.
“I thought there was no way we were not going to find her. We did end up finding her but not in the way we would have hoped,” says Karabo.
Olorato’s body had been dumped at the dirt entrance of a random house less than 100m from where her friends were searching into the night.
Her face was swollen and her eyes black-blue from violent impact. Her top was ripped open to expose her breasts.
Police told Sky News that her post-mortem showed signs of blunt force trauma. She was likely beaten to death.

“It was like I was dreaming, seeing her body like that with those bruises and blood everywhere,” says Olorato’s mother, Keabetswe Poppy Mongale, describing the moment she had to identify her only child at the morgue.
“I don’t think what I saw will ever go away,” she adds.
“It was very painful. I don’t wish that on any parent because my beautiful little girl looked different because someone chose to do that to her.”
Olorato’s mother says the image of her daughter in the morgue will never go away
CCTV from the driveway of Olorato’s building shows the last time she was seen alive, leaving her home to meet ‘John’.
In the video, she walks towards a white Volkswagen Polo and hesitates as she reaches the left back door. John had come with a friend.
Four days after Olorato was killed, police found the car in a different province with traces of her blood splattered across the back seat.

One suspect was shot dead but the second man is still on the run
Philangenkosi Sibongokuhle Makanya – ‘John’ – was shot dead by police in KwaZulu-Natal shortly after they found the vehicle.
The second man in the car, Bongani Mthimkhulu, is still on the run.
The two men have since been identified as part of a dangerous criminal syndicate that lure young women out on dates and rob them at gunpoint.
“Within the four days, the investigating officers received 94 calls from women who were raising concerns and identifying the suspects as those they once met,” South African Police Service deputy national commissioner Lieutenant General Tebello Mosikili told Sky News.
“It was unfortunate about Olorato, but others were released after being robbed.”
Olorato’s friends say she ‘ticked all the boxes when it came to being careful’
A 24-year-old student who survived an armed robbery at the hands of Olorato’s suspected killers says she was happy to see Philangenkosi killed but she’s still scared for her life.
“As women, we are not even safe anymore – we can’t even walk freely,” she says.
“The moment you leave your house you wonder if you will make it back alive. I don’t feel comfortable walking around the street. I leave the house and then turn back.
“Even when I’m home, I still don’t feel safe and always want to keep myself locked indoors,” she says with a shaky voice – choosing to remain anonymous.
After meeting other victims of the syndicate, she was shocked to hear details of almost identical abductions.
“This other girl was surprised because we went through the exact same situation. They also approached her with the same tactic – let me take you out to lunch to get to know you – only for her to be robbed.”

South Africa has one of the highest femicide rates in the world – an average 15 women are killed a day, many by their intimate partners.
According to police statistics, more than 5,500 women were murdered in South Africa last year. An increase of 33.8% compared with the previous year.
“South Africa has six times the average rate of femicide – hundreds of women have already been killed since Olorato’s murder,” says Cameron Kasambala from Women for Change.
The advocacy group raises awareness of rising cases of femicide and gender-based violence across South Africa.
Campaigner Cameron Kasambala says many femicide cases take a long time to be resolved
In the hours after her murder, Olorato’s friends contacted Women for Change to share her missing poster after receiving little immediate help from the local police station.
“I think her friends were the real heroes in that moment,” says Cameron.
“Two police stations that were 10 minutes apart, one finds a body and one has a missing case, don’t make a connection for hours. It’s not the most reassuring police work. And if the friends had not come forward, how long would it have taken?
“Unfortunately, Olorato’s case is an exception. Most cases are not handled that quickly.”

Olorato’s friends say she would be ‘proud to know that her name has not gone in vain’
Olorato’s friends are still contending with the violence of her death – what it means for their daily lives and how they navigate their safety as women in South Africa.
“It is difficult to process and difficult to believe. This is somebody who ticked all the boxes when it came to being careful – being meticulous, checking her surroundings and leaving clues,” says Olorato’s friend, Koketso Sejosengoe.
“It shows it can happen to anybody no matter how safe you are. It is happening to the average girl. They are being targeted. These men know what they are doing and who they are looking for.”
“In the purest sense, Olorato wanted women to be safe and wanted women to be protected,” adds Koketso.
“I think she would be very proud to know that her name has not gone in vain and that her death is standing for something – that there will be change that comes with this.”
Major heatwaves across southern Europe have left Spain, Portugal, Italy, and Greece in sweltering conditions of more than 40C (104F).
Two-thirds of Portugal was on high alert for extreme heat and risk of wildfires on Sunday, with temperatures in Lisbon expected to exceed 42C (107F).
In parts of southern Spain, temperatures are well above average, with 42C also expected in Seville and other cities.
The country’s meteorological service says June is likely to be the hottest Spain has experienced since records began.
In several Italian regions, including Lazio, Tuscany, Calabria, Puglia, and Umbria, outdoor work was banned during peak hours of sun on Sunday, with trade unions pushing for the measures to be extended and rolled out nationwide.
Twenty-one out of 27 cities were under the highest possible heat alert, including Rome, Milan, and Naples.

Scientists link increasing frequencies of extreme weather events such as heatwaves, wildfires, and storms to climate change.
In France and Germany, at least three people died amid stormy conditions.
A ridge of high pressure above central and western Europe is driving the scorching conditions, says Sky News meteorologist Chris England.
Hotter-than-normal sea temperatures, dry land, and surface winds are also partly to blame, he added.

UK heatwaves explained
The UK is halfway through a four-day amber heat health alert, with temperatures expected to peak in the mid-30s (86F) on Tuesday.
Heat health alerts are not public weather warnings – but are instead designed to prepare health and social care bodies for the potential impact on their infrastructure and vulnerable groups.
Heatwave thresholds are likely to be met on Monday and Tuesday, which vary between 28C (82F) in the south of England and 25C (77F) across the rest of the country.
