- Industry is responsible for almost half of the world’s CO2 emissions. And heavy industry represents the lion’s share of those. But heavy industry is under pressure to make the switch to renewables in record time. A mammoth task!
Environmental protection is important to Mohammad Safi. He rides a bike and powers and heats his home with solar energy and a heat pump. The engineer is keen to keep his personal carbon emissions as low as possible - ideally, below the German pro capita average of 11 tons per year. An amount dwarfed by that of Safi’s employer, the steel giant ArcelorMittal.
The German steel industry emits more than 30 million tons of CO2 annually. Together with the iron and cement industries, it’s among the world’s major environmental offenders. But: ArcelorMittal wants to change that. The manufacturer is testing a new production method that doesn’t need blast furnaces. This could cut emissions by two thirds. And if the plant switches from natural gas to eco-friendly hydrogen in future, the footprint could be reduced even more.
EGA’s aluminum production plant in Dubai is also exploring ways to make the transition to green energy. Currently, operations there guzzle as much power as the whole of London. But in future, this electricity will no longer be coming from a gas-fired power plant, but from the world’s largest solar park now under construction in the desert.
When it comes to cement, things are more complicated. CO2 is released at several stages of the production process, including burning fossil fuels to heat kilns and in the mining and transport of raw materials. Researchers at Dresden’s Technical University are developing a solution: concrete reinforced with carbon fibers instead of steel. The carbon fibers are much more robust, meaning less material is required. The technology is being trialed in an initial construction project.
But will all this be enough to ensure that the world’s biggest environmental offenders can turn things around and go green? The reportage explores the challenges and presents glimmers of hope on the path to eco-friendly heavy industry.

Thanks for saving my time!!!
Thanks for saving my time! Love this summary tool called Tammy AI! Where you download?
Just one correction in this summary.
The entire industrial sector (including steel) is responsible for 43% of Carbon emissions. Not just the steel industry
Industry decides how the climate crisis ends. People can help and nations can regulate, but industry has the deciding role.
Not a crisis.
@@marcinpajak6252 it absolutely is a crisis, you’re in denial
Not a crisis but a doom
Great documentary! Really intrigued about the role of innovative engineering solutions in curbing emissions within heavy industries. What breakthrough technologies are on the horizon?
Thank you for watching and taking the time to comment!
It is entirely possible to build a mechanical climate machine that will halve the rate of global warming. But unfortunately, “climate activists” are more concerned with making money than solving the climate crisis.
Incredible work. Thank you so much for these documentaries, I’ve been binging them lately. Keep ‘em coming!
We need to erect wind turbine farms everywhere in Europe on a industrial scale.
Very alarmist.
@@marcinpajak6252 and how do you know that bud? You sound like trump
@@marcinpajak6252 care to elaborate? We should be alarmed
CO2 is plant food, it also keeps the earth warm, saves us from an ice age. Ice age would the real crisis. We should put more co2 into the atmosphere. It’s called terraforming.
so easy when your making the big bucks like this engineer...
Although I don't believe we have the time and technology to change the game, it always moves me to see the efforts of many people to try to save the planet. Yes, you have to try, dying trying is better than doing nothing.
Please. We CAN change the game. We just won't. Don't get it twisted.
@@theLampSA Imagine that you are driving a car and enter a very narrow street. You believe there is an exit ahead and continue driving. But little by little the street becomes narrower to the point where you are now driving between two large walls. You can't maneuver. You can't go back. You can't open the door or the window. You can't get out and you'll die in the car. This is the civilization we built.
I'm not trying to blame us human beings. When a child puts their finger in an electrical socket they don't know what they are doing, we don't know either, we just move on.

Either way fate is the same
@@andacomfeeuvou We do know what we're doing though, we've known for a long time. Imagine that same child, we'll call him Bob. Bob screams 'YOLO YOU'RE NOT THE BOSS OF ME!'
I posted this reply to another comment on another video. Trolling? Or only saving time? That video had more to do with "right to repair" and 'planned obsolescence" . It seems fitting here also.
Yes, but some 'experts" believe and say it's already too late. We are past the tipping point and it will snow ball from here! Only SHADE 😎can slow the warming,
Parasols in space! If we can do that, then it would make sense to tidy up and keep the environment clean and our efforts may not be in vain. Too many people don't seem to care. Or don't believe or don't know how to read a thermometer. It's part of the dilemma of man. Deceit, fraud, deception and misrepresentation are seen as being cunning and ingenious. You have me using the dictionary. Check it and you can see that cunning as an adjective you'll see that cunning can be ingenious or deceptive depending on what you are describing with the word. I look at it this way. We all live on a finite ball in space, our fragile life boat that is sinking as we are fucking it up because the need for bread trumps decency (the dilemma of man).

Damage already has been done it’s too late. We must deal with the by product of greed.
Great documentary DW like always! Thanks again n again!!
Sadly our European and Western countries still rely on 3rd world countries labour for production of mining for this Green Energy 🧐😭
Mohammad Safi is a good example
A wonderful documentary shared by an excellent (DW) documentary channel ....about adoption of climate friendships heavily industrialization processes..thank you for sharing
All good stuff. Given that, currently, about 30% of the population (here in canada) cannot afford to buy adequate housing/rent, food and transport. And that 30% will only increase as income inequality increases. Interesting times.
Time to leave our great nation :/
What happens when you can’t get specific parts for your tankless boiler? Or are parts more readily available there than in USA? Parts take over a week just to get shipping started here
@3:56 It is a safety violation to open a peephole of very hot material with your body directly on the way. The Engineers were supposed to stand on the side and stretch their hands when opening it. This is to avoid contact with an unexpected gush of hot material from a broken protective glass.
The car industry, one of the biggest offenders doesn't exist without consumers and consumers can help by not purchasing or upgrading unnecessarily..
We need to erect wind turbine farms everywhere in Europe on a industrial scale.
What about the poor in 3rd who also want to consume and live well ?
That is capitalism. The economy was built on that. Nothing will change because governments want eternal growth.
Extremely important subject. Thanks DW
I have yet to see DW make any documentary criticizing the four public corporations that pollute the most and contribute to global warming. Is DW a supporter of the US Army, US Navy, US Air Force and US Marines?
"the four public corporations that pollute the most and contribute to global warming. Is DW a supporter of the US Army, US Navy, US Air Force and US Marines?" - first off, militaries are not public corporations. Secondly, they are not the biggest contributors to global warming. You are copying nonsensical claims from somewhere on the internet.

Lets be honest: we COULD change the game. We just won't. Everything that happens to us, we asked for. I've made my peace with it all. I accept humanity's fate.

Even if you accept that unacceptable reality, humanity is not a monolith. Some people are profiting, accruing benefit from the direct sacrifice of others. Not only should we have the right to not have our planet destroyed, but that planet is still finite. Consuming the common resources and changing the shared atmosphere unsustainably, and then not sharing the benefit is a distributional injustice. Ignoring that the world is zero sum, just adds insult to injury. Why should we be at peace with a game we don’t want, that doesn’t benefit us?
@@Rnankn Humanity is a monolith. We all make individual choices everyday that prop up the status quo. Humanity is self serving, selfish, and cowardly. Otherwise, things would be different. That's the truth, mate.
Wow so much positive energy here
@@madkiwi62 "Your house is burning! But you look so much prettier when you smile."
What an amazing documentary!! It's these very heavy Industrialized emmisions that are indeed the biggest 'offenders' and need all the best of humanities brains to be able to limmit! Great that the Germans are leading the way in this!
We are mostly about local emissions. Worldwide emissions involve worldwide cooperation
SSAB in Sweden and their HYBRIT steel already produces next to no C02... however it is the production of green H2 that is the tricky part. You need green electricity to produce green H2..... which is possible.... You need not stop there, the mining of iron ore is another area to look at..... we can run our mining equipment on batteries or overhead trolly lines - which are then charged with green electricity.... then there is the explosives.... there is great work ongoing using H2O2 as the oxidizing agent - instead of the traditional Nitrogen based solutions. We can be much greener - the core technologies are existing and/or developing fast.... at the end of the day it comes down to a question of cost. Though is it really a cost... or an investment in our future?
DW are doing excellent work in recent years with their documentaries. Bra jobbet (from Sweden)!
@@NotShowingOff There's just something like 100 companies that are the major cause of pollution and the global warming greenhouse effect. That your individual efforts taking personal responsibility have any impact is the grift to sidetrack you from demanding those companies clean up their act at their sacrifice of a few quarters to a couple years of profit dividends is how this problem has persisted for over a half century now.
@@NotShowingOff China and India burn more coal than all other nations COMBINED!
please include the name of the company that is developing this carbon mesh, there are a lot of people interested in this technology and it would be important to know the creators
Inspiring
Yes. It’s an attainable one. Thanks DW
I ve been waiting for new video 🎉
Tell us what is the per capita emission of Germany?
I wish you and your family a wonderful life. I’m happy to see industry sacrifice a few dollars to make a difference 👍

Let's be realistic here, the majority of the world industries will just go for the cheaper option.
As long as the fossil fuels are cheaper, there is no real incentive to change anything.
Maybe a world wide carbon tax could incentives the industries to go for carbon free methods of production, but i think it's highly unlikely for all major countries to agree to do such thing, especially that this tax will be paid by the consumer.
Such policy will be extremely unpopular for any government. Also the countries that are not as rich and technological advanced as Germany, will definitely not be able to do it without killing their industries (and good luck with that).
Maybe we should try to concentrate our energy as a species and as individuals in something different then mindless consumerism, we don't actually need all the shit we have. We have great methods of convincing people to buy things that they don't need, we can use the same method in reverse, but that will be the end of capitalism, yeah good luck with that.
I think it's time to accept the inevitable, that bilions will die and we will probably go extinct in the next 2 centuries, we had a good run and we achieve amazing things. The flame of consciousness shall not die with us, surley in this vast univers there are countless civilizations.
The real question is "do they even give a shit?"
The building material reuse (as described) seems like a complete fantasy. The core issue is timing verses directly moving materials to a receiving project. This means that either the remodel project waits to move materials out to when another project can accept them or new projects wait until the materials are available from deconstruction. Considering that multiple new project will be fed by the deconstruction, it's impossibly complicated. Project timeline is what makes a construction project successful or not. This is just nonsense.
It seems better to do the deconstruct project and warehouse the salvageble materials. That might be a bit more transport, but it fits the construction industry. I think that's what they are actually doing. Directly send to another project may be a goal or preference, but there is simply no way this happens very often.
The nation state model is our biggest obstacle. Clumsy awkward and violent. Overly competitive leading to over production, too many facilities, inconsistent planning based on man made borders.
The answer to the question is - NO.
We’re all doomed.
Using Carbon concrete is super good idea.
Can hydrogen actually replace the role coal and gas have in steel production? It’s not just a source of power. Steel is formed as an alloy of iron and carbon. When you refine iron in a smelter with coal, the carbon molecules from the coal bond with the iron and that’s how we get steel. Hydrogen can obviously be used to light the flames but we still need a source of carbon to bond to the iron.
Great i love DW documentary interested in climate
Thanks for watching and for the feedback!
Burning h2 does eliminate co2. However how about produce h2? Where the electric come from?
You should see Ust-Kamenogorsk, Kazakhstan. Every single day heavy metal emissions. People live or exactly to say survive here poisoning like cockroaches.
Maybe cowfarts can stop pollution.
You willl eat the bugs to make the climate "gooder"! LOL!
unfortunately the ppl working at the plants are helping destroy the earth no matter the changes in their personal lives
making changes industrially is good but i think not quick enough
i dont know if eating more veggies is helpful cause of large scale farming
Time to take action
Great & informative documentary 👍.

Dubai did NOT get rich on O&G; got rich on real estate. Not that I dislike the Doku, but let's not perpetuate ME stereotypes.
I’d love to live carbon neutral. However, I’m not a millionaire.
The richest people have the largest carbon footprints.
@@mitkoogrozev very true… I guess what I meant was being wealthy enough to buy an eco-house with all these eco-friendly appliances and means of gathering geo-thermal energy
@@MikeJones-yo8en Yeah. With the current prices and the interest on loans, many people can't even afford a home, let alone the necessary additions to make it carbon neutral. We recently went to the bank to see what it would look like to borrow €400000 over 25 years. Apparently that's now almost €250000 in interest. I almost fell off my chair. I can't imagine hearing that while you're single and not earning much (and yes, in that case you wouldn't borrow €400000 but relative to your income it would still be just as insane). Crazy times we live in
Stop buying canned foods and beverages. You'll save money and reduce carbon footprint at the same time.
😂😂
Using hydrogen for fuel instead of electricity is a very dumb move because hydrogen is produced using electricity. So why not use electricity directly using the method of induction? It would be more efficient. With induction method you can gain much higher temperature and in a very short period of time.
I was wondering the same. I work at a stainless steel plant and they use electricity to melt the steel, in an electric arc furnace. They solely use recycled steel, too. However, I do not know enough of the steelmaking process to determine whether or not there's a reason for not using electricity. I assume there is. Though, it could also simply be because of money, because if they wanted to use electricity in the plant in this video, they would have to revamp the entire plant around EAF steel production. I'm curious as to the reason... And of course even though we use electricity and even though we only use recycled steel, we are still a huge emitter of GHG's
@@BinaryBlueBull Your company used other kind of method, which I think is not efficient and old method. I said using the method of induction will be more efficient.
@@tech9110 Ah yes of course. I don't know how I glanced over that. My mistake. EAF is obviously not induction. I didn't even know they used induction to melt steel in such quantities, since our melting pots hold up to a hundred metric tons of steel scrap. Also didn't know it is inefficient. Thanks for correcting me, going to do a bit of reading on induction steelmaking and EAF efficiency
I love DW for bringing such amazing short documentaries on Climate Change and it's Solutions. Love for DW from India 🇮🇳❤🇩🇪
Thanks for watching and taking the time to comment! Kudos. :)
Changing industry is expensive but extinction is A LOT MORE EXPENSIVE .
thank you so much for your science
Doubt we will arrive at a fast enough solution. Not with countries like India buying Russia heavy high sulfured oil and mazut oil bottoms. Expect India's pollution output to dramatically spike in the next 10 years well past China. The issue is India's economy is more young and developing than China and has yet to develop a modern green manufacturing and green power infrastructure. That all takes money that India does not have yet. Transitions are always painful and slow.
Government should stop them
Can the leopard change it's spots?
Only realistic thing left to do now in my opinion to stop climate change, is to accelerate it to a point, where it becomes dire enough that people have to take it seriously, cause it starts to influence their basic needs, and the cost of stuff like natural disasters becomes so high that stopping climate change becomes cheaper than not stopping it. Sometimes it has to hurt enough before change happens.
Climate change cannot be stopped though. It changes naturally, whether you like it or not. As for natural disasters, a basic statistic shows that with each year, less and less people die due to natural disasters and less damages are also reported as well. So no, no change is needed. This ecobullshit is what is hurting people.
If we had one leader to force everyone to make the radical changes required to adapt, then we could survive long enough to develop the technology to reverse climate change. I'm not sure if this justifies authoritarianism, but it's one option we haven't tried. We need to adapt - at the very least - and we need proper leadership to do that.
you can only say that because you don't even experience it.... and when you do what will you do???

Climate resilience mandates the development of robust infrastructure, preparing communities to withstand the increasingly frequent and severe climate-related events anticipated in the wake of global warming.
We're currently heading to 3 degrees above pre-industrial levels. The money and political influence from the oil industry has indicated they don't want to evolve, even if their delaying actions while increasing short term profits, will result in a world where money won't matter anymore (this could be within the next century). So they are locking in a global economic crash that modern humanity will not recover from.
Not under capitalism lol
We’re fucked!
Short answer: NO!
May the Anthropocene (Pyrocene (?)) epoch make the Permian-Triassic extinction event seem like a minor footnote in the pages of Earths history. Hopefully, scenario SSP5-8.5 of the IPCC assessment comes to fruition and ends the Anthropcene. Enjoy what you can, while you can and pity the next 3 to 5 generations to come.
I will do my part driving an electric car with it's eco friendly 400kg battery production of which emits 10t of CO2 and later recharging on electricity produced by burning coal... Stupidity is a blessing....

"Saving the planet" it does have kind of arrogant tone to it, doesn't it?
is Germany already in equatorial Africa?
CO2 is bad? Seriously, I thought that's what trees and plants needed to live.
Oxygen is also needed to live, but if it shifts out of the 21% of the air bandwith there will be big problems. Outside of the bandwith/sweetspot systems need to compensate and that has limits.
"I thought that's what trees and plants needed to live." - you have a deficient education.
@@TheDanEdwards Your comment is typical of those on the left. Instead of engaging in a conversation, the tactic is to simply insult the other person. Are you saying that trees and plants DON'T need CO2 to live?

sorry to say this but what happnes to this worlds climate, we have to accept it and just live with it. The climate is changing no matter what. If it makes you feel better to ride a bicycle to work, use solar panels then good for you. But it won't make a blind bit of difference.

The public should know about the indirect cost of renewable energy. It may take 10-20 years to break even but it's a good investment for future generations.
Eweou Believe in Santa Klous and the Tooth Fairy as well then.
Try Free Energy.
Only one real problem that I see here and that it's all based on limiting and/or removing CO² from our atmosphere. Seems they are forgetting another byproduct of all types of production, and that is heat. Heat that is generated and dissipated, ever increasing the ambient air temperature. This heat dissipation is almost as bad as the CO². For now, I believe, we just need to decrease/stop production of non-essentials; therefore, setting a basic essentials standard around the world.
"This heat dissipation is almost as bad as the CO²." - last I looked, waste heat globally is only about 1% of the size as the net energy increase from changes in CO2.
@@TheDanEdwardsAll energies used turn to waste heat eventually unless trapped or stored.
industry will only change if there can be profit made from change. thats capitalism. the only thing that works is strict regulation
There's wayyy too much focus on individual contributions here. Even if someone could go totally carbon neutral, one person doing it wouldn't offset even a tiny pig farm.
Vote, be loud, convince others to vote
Entire Western countries could cease to exist, and it would make zero difference.
They can, but they won't. "The love of money is the root of all evil." -The Bible
Your bible is wrong. It's not the love of money, it's the love of power. There was no money in that era, only gold, silver and etc. So through your bible in the trash bin.
No
The future must then be the time from now until the collapse of civilization. After that I don't see a future.
Maybe if we all are forced to drink cat-piss coffee from the Amazonian rainforest ; then we could stop changing the climate.

Effective documentation
Minute 25:23, the Japanese experience of earthquake proof infrastructures is teaching us that this concrete heavy buildings constructions is obsolete by now, l see them buildings work like a human body, on elastic skeleton and LEGO bricks to live in, big stadium arenas are built ...easy structures, not concrete heavy ones, can you imagine it? Next to carbon fibers use, there's the glass fibers that work as well for replacing the heavy cement and classical stones bricks for constructions, think about it, watching such documentaries together we have to step forward and be more...German style, faster, cheaper and smarter, building up convenient homes and safer anti earthquake as well. Each time natural catastrophies happen, stadiums are the safest refugees shelter, then why not building stadiums infrastructures for domestic use from the first step? Sometimes floods seems to me a prophetic sign, we have to raise up urban areas from the ground and let them water canals save the rain water when it comes, those who care to replace old heavy buildings with earthquake proof easy ones, let them do it, no matter here in Europe, Afghanistan or Morocco, on top of ruins, new homes can raise up and. ...shine❤🎉❤
Better question. Can we stop pointlessly crippling western economies over this climate change fallacy?
Canada and the UK could disappear tomorrow and the effects on global emissions would be negligible.
So why are they crippling their economies over it?
Minute 23:40, the carbon fiber manufacturing, did you see the Zaha Hadid architectures? Her buildings look like airplanes. Pollution is not about burning fuels only, but trying to catch the smoke, the ashes and bring them down to the ground before they get high in the atmosphere, we know by now how smog is dangerous not only for breathing, but it's increasing the solar radiations which cause cancer troubles all of us, if we do not start doing something, we all risk to die like idiots. Instead of huge highways, we could build up carbon fiber tunnels on top of most roads and streets to vacuum right away the vehicles pollution and make of these tunnel a new resource of electrical power, saving fuels by having fresh air outside the cars, no need for further conditionating systems for vehicles, yeah, can you imagine it streets looking like stadiums arenas all convered of spectacular roofs? All we need is get inspired and ... Chinese partnerships might help, the convenient handymen are still worthy and they are so fast to do the job done in six months or so, we can not .. chit chat about environmental projects other 50 years from now on, we are talking about these topics since the '70s and big industries have no intentions do nothing about it. Mostly oil companies, if they have alternative resources, saving oil, it's their huge advantage. For how much we try to build anti pollution infrastructures, a lot of oil might get involved and burn. If we care to dismantle the African desert, we can bring the water to the inner lands, that will ask a lot of fuels as well, before we start to breath again... yeah, what a wonderful world this could be friends, only trying to dream about it 😢😢😢
Now that scientific knowledge is average TV entertainment friends, there are many more solutions to fight back pollution and global warming, such as, using carbon fiber instead of metals, is it less polluting or not? Buildings must work like trees, vegetals are the only ones manufacturing oxygen and purify the toxic atmosphere, can we find solutions to fight back crowded urban circulation? By building alternative transport ways, such as water canals and underground tunnels, yeah, let's use steel and metals for building up rollercoaster bridges for aerial cycling lanes, let's give everybody the chance to use bicycles more often and let urban areas breathe for a while. Out there on coasts there's so much wind, if we could only have the will to plant more wind mills having alternative electrical power, if it's possible to find a vegetal capable to manufacture the chemicals we need for electrical batteries, yeah, a lot of work to do friends. Why do we need big giant electrical companies to split then the power for all the tiny domestic devices we need for our everyday lifestyle? What if every electrical device could work like a smartphone? Having an independent battery based on solar panels power...a lot of work to do guys, all solutions are welcomed. Ask everybody boycott the excessive alluminium use for ridiculous beverages packaging, how much do they pollute? What if everybody start to drink the Coca cola from a thin plastic water bottle? Still the plastic is the easier to be recycled, much easier than...tin cans
Agitprop
I am all for countries like Germany who think they can do their part to limit CO2, but the idea of hitting the CO2 target as the be-all-end-all is rather silly. We Americans are not going to do that, China and India are even farther away from being able to do. In the end, the earth will warm and we will all adapt and live on.
Oh, bloody hell, surley you jest...............humans just need to go away, period, this pale blue dot out in the cosmos would do just fine - people need to go!
no humans will wipe ourselves out and the earth will move on without us
China is not further.
Too little too late
fake premise
When humans were using club. Arrows and spears theee were less hu.ans when they duscover nukes they exploded to 8 billion😂
Hydrogen really thats not good at all.
The amount of power needed to make it then the tanks to store it and it will leak out no matter how you try.
Then theres the transport then it burning has so many steps its less efficient.
They would be better off using a ark furnace usa uses lots of these it just needs energy steel a little iron ore and at most some co2 to make the co2 but they dont normally need to add the co2.
They use this for aluminum too but its like 5% less efficient then the steel why idk because of the metal structure not sure.
Ps ark furnace is about 97% or more efficient where Hydrogen is like 40 to 60% after everything i mentioned above is done.
Oh ya i forgot hydrogen furnaces will need co2 injected in to make steel for they hydrogen will strip co2 out of the steel if they dont making it very brittle.
Oooo concrete well i got a better one for ya thirsty concrete.
If used in roads wich lots of roads are made of concrete thirsty concrete can reduce noise pollution by car tires by 5 to 15% it can reduce flooding and sand mining for it doesn't use any sand at all.
It can add water to soil and underground aquifers by the way they build them and there just as strong as normal concrete by only 5 to 7% weeker but good enough for a simi to drive on it with 40k pounds.
We need degrowth!
NOPE!
