that is really sold we to, to full of prison in the army officials. unicef has accused israel of crimes against humanity is the day starting september 30th on d. w. the steel, aluminum cement, indispensable for us all. but their production is a gargantuan problem for the environment in the winds of if we wanted to save time into this, we need to perform the change industry because it's heating up our planet

with greenhouse gases and an insatiable appetite for energy re bearable. once we utilize the re thing is beginning slowly but urgently in radical change doesn't occur in these industrial sectors. we won't be able to hit the targets. how can the vague environmental offenders clean up their act? the climate friendly commute to work? dr. mohammed fees routine for 15 years and been i cycle to work whatever the weather. i say it is a challenge, me just as a task,

if at all i need to do my bit of god in both my professional and my private life. oh, my buy talk nice. but in the workplace, that's not so easy for mr. sophie. his employer produces steel, making it one of the big environmental offenders. the engineer is deputy plant manager at a settlement. tom and humbug. responsible for the smooth running of the furnace is the steel. we can manage without it. it's in buildings. vehicles and household appliances the but it's production is harmful to our climate. and the steel industry isn't the only offender if you include energy and heat

consumption in the mass, the industry is responsible for 43 percent of global emissions. significantly more than the construction and transport sectors. more than 70 percent of industrial emission stem from the manufacturer of just 3 basic substances, steel, cement, and chemicals. steel production was responsible for some 3000000000 tons of c o. 2 in the last year alone. mostly to blame. the blast furnace is the where the vast amounts of coal or burned the production of one ton of crude steel result in 2 tons of c o 2. normally. but not in humble here. so things happening. that's

a better fit for mohammed se philosophy. i'm personally trying to live in eco friendly life. that's why i'm pleased with the process i'm working in is also climate friendly and isn't closing last thing, environmental damage. but how's that supposed to work? climate friendly, steel production. the 1st ingredients, natural gas replacing coal as a source of energy, the se, minutes less c o. 2 ingredient number 2, steel, recycling, cutting emissions by 2 thirds compared to production and the blast furnace. but researchers see perhaps the most potential in green hydrogen, a source of energy seen as a future replacement for coal and gas, which is expensive. and now in short supply it's

a crucial time for mohammed saucy and his boss. hoover brown. they're discussing where to locate the new hydrogen plants. use it to v. somebody talk with the trailblazers. that's for once we've got the means to move things in the right direction. but we also need supports in a political level stuff. on the one hand, we need vast quantities of hydrogen. we need to green electricity, and of course the economic framework for our products. in other words, it's going to be expensive on the road to emissions free steel, who's picking up the time. and how long will it take? germany's climate action package sets out and then vicious roadmap for the year is up to 2030 economist katya. a few months us as much of the pressure is now on industry is to me on so i don't a lot. i still needs to happen before 20135 emissions have to be reduced by another

30 percent or for you to invest in or if it's in the government's official. projection report suggests that it's significantly gratian if it's on may now, industry won't. agents targets in 2031 of the fits. what is your value to the understand what the some individuals are well on the way to hitting their targets. one of them is mohammed stuffing. he tries to adopt a green lifestyle wherever possible. he built his house in 2012 with environmental protection in mind. there are solar panels on the roof. his heating system runs on geothermal energy, making it 100 percent, clement neutral. but for the engineer, there's always room for improvement. together with his sons, he weighs up how to make his home even more eco friendly. dishes,

then are at the moment, the roof only has solar panels facing south and west on. so it would be good if we could include the eastern side to use the sounds energy in the mornings to offload some con compared to what industry needs to do. his contribution to climate protection is tiny, but either kind of best buy tom and everyone can play upon whether it's separating trash, installing solar panels and not using electric cars or public transport and looking for an certificate that then if every single one of us makes little contributions like these, of course, the overall effect will be here at home, but not nearly as huge as measures taken by industry. after all, it's been producing the most harmful substances to date. but can these admissions also be useful? the steel production at 2 isn't called

into sports. here experts are holding in on waste gas is from steel production, primarily carbon dioxide and carbon monoxide. in the past, they were usually flared off the physicist marcus bonus, now collects them with his plan. his goal to utilize waste gases as of raw material this is towards smoothly today. it's not possible to design old chemical processes in a way that produces noise, c o 2, with all the start and that's of and still making use ultimately a chemical process. you can send what you get. the question is what to do with it off to would start off. and we think we found an answer within this 32 pos on remaining c o. 2 emissions from one industry to the next in those where they can be recycled as a rule material to watch stuff. so for the mock as old as his

keen to find out this can work together with colleague tim. so it's got the engineer from the fallen hole institute has built a test plan to produce a method all using waste gases other necessary ingredients, hydrogen and oxygen. eco friendly method all works well as fuel in the shipping industry. for example, the a mess, an old howard ferry is already applying. the water is between teal and gotten bur waste gases for method all production. if it works, it's definitely useful. some it's on the method, all approach makes it possible to remove c o 2 from the still works process and turn it into inputs, materials for the chemical industry like the money you bought,

bite, eat lunch, balancing things as the steel industry on the one hand on the chemicals industries together and come on means you can pretty much cut c o 2 emissions by half. sounds like a win win situation. but how developed is the process? let's test the circuit, gus, full of and ready to open it. okay, then i'll count down 3 to one. open. the plant must always be operated by 2 people at the same time. for safety reasons, and case toxic gases escape. you can relate the pressure now. pressures and the 6 bar and small. and the gas bottles a blend of typical waste gas is carbon monoxide and carbon dioxide. both extremely harmful to the environment. a small miracle occurs inside the plant.

the addition of hydrogen creates valuable climate friendly method all ready to take a simple hope of develop no place. okay, and there it is. the substance that could eventually clean up steel production. but it'll be years before there's enough of it for large scale industrial use. police complete, please close the valve. cover for me just use a fishing of holding on. so holding this liquid sample in my hand is a big success for me because it was a real fight. it's getting the details of the project right? well goes and it will be even greater once the 1st production with waste cost is us taking place at the $2.00 spoke. still works on the 4th is all at this stage. i'm very pleased with what i've got to my hand on the team, but the here and on top a small model that represents

a huge change. if the industry is serious about protecting the climate, vast plants will need to undergo a thorough remodeling. this will take time, but a window of opportunity is about to present itself. after all, many plants have had their day. studies have shown that these sorts of investments in the industry do over the next 8 years. and if we make clever use of them installing and investing in the climate friendly technology has now been targets might be re this has to happen across the board and not just an individual plan. i've talked to young with this new an item and i've done tiers. it's precisely the other way around. the focus isn't replacing the old but reusing it. civil engineer, i mean, not double ave, and her team are here to salvage construction materials to protect the climate

this office building and fund, so it is about to be renovated. usually much of the discarded material would end up, but that's down. it's a waste of resources that are themselves responsible for creating a lot of c o. 2 says, i mean not that blind. a she's been commissioned by the real estate company to give a 2nd life to as much of the construction, but to real as possible. the 1st step is documenting every section of the building for a specified on average is maybe it's important that these can be adjusted and that you can make them narrower before you put them back in mind that you got involved contest, photos for the catalog. and it's hoped even this turn style will find a new owner to the system and you'll get his custom via a respite clay we can reuse all types of building material. bolden b flooring doors on staff in great section of some get talk austin elementary to

kind of a little bit i'm thinking will be removed and reinstated. and i know we just have to ensure that deconstruction is worth while by the end of each element is recorded . and in that anyone shopping on here can ease their climate conscience a little for using material means saving on the c o. 2 produced in primary manufacturer ideas like this are urgently needed, but mindset change in the building sector is sluggish. in that sense, in germany, unfortunately, only one percent of materials currently we used, although sometimes the condition of these building materials this bill adequate for reintroduction. can also hypo, sometimes they just need a bit of preparation before they can be re utilized of the hyphen vatton. but unfortunately that doesn't happen that in this this means a lot of stuff is ending up at the dump when it could still be very useful. says i

mean not to blah hey. yeah, so what about these kitchen work tops, for example, they're showing years of wear and tear i'd say heavy use because for us the old used to call us then we'll have to change of the listings. yeah. yes. or maybe yes, it's not always easy for the video flow coverings, for example, the test on down also degraded that they might be polluted in such cases and we have to think, okay, what can we save and what's out of the question that's can every building is a new challenge gate is where we go through all the materials on say, okay, and then what can we do here? is that ok of us? can i do him a gradual, least a catalog take shape? and it's all the available construction materials of a building. anyone wanting to build something new, can take a look. what could suit my purposes the materials are only

removed after they've been sold, then they're sent directly to the client with no detours to keep c o 2 emissions to a minimum. thank you don. yeah, he is responsible for remodeling this building. the real estate developer wants to align the property with current standards, avoiding a classic renovation. that's to damaging for the climate not everything has to go. these partition walls, for example, are staying put because they have a time list beauty and they're in good condition. switched on. and the actually could paint would be nice. but otherwise i reckon that totally reusable. i thought of in a don. yeah, he does, sees the future of building as a circular team is tjuana. investors want to ensure that the money is being

invested in sustainable profit is this requirement is undoubtedly more crucial now than it was the impulse decades single sentence. in that sense, it's a must even if it's more expensive, but it's a process. so transformation with great participation, it will become easier to transform existing materials like these and re fits them. it will also become cheaper and more economical to replicate these processes to go to the top of the server with one of these reports that we could update and kind of modifying industry must remain affordable if it is to be a success, as many people as possible need to be on board the power of the masses, something mohammed, some fee from humbug also believes and he knows that the climate struggle can be one through his actions alone. but he does what he can for longer journeys. he uses an e car and he does what we could all do more often. he usually

runs the washing machine on eco mode. but the appliance next to it. that's already big lead climate protection is kind of yeah. and then bethany and the put the test button here on the pay the battery. i can see the precise charge level and current power yield. and i can also see it on the app and decide whether now is a good time to run my washing machine. the dishwasher for tumble dry out in the moment bundle this machine. uh well this also helps me save electricity on my phone with a nice product. that means kind of josh, for me please con a. saving electricity to protect the climate. the solar panels on the roof do most of the work here. as for the new panels for the east facing side, mohammad southeast has already ordered them. the power direct from the sun in works,

even in northern germany. what about places where the sun shines all year round? places like do by the me or it on the persian gulf is aware of the world appetite for green electricity and has an offer for the climate defenders of large scale industry and future buy solar power from the deserts of 2 by side of the world's largest solar park, the 2 by god, rich on oil and gas, but the eminent wants to end its dependence on fossil fuels and is turning its attention to renewables. the but these solar power viable and heavy industry. a sector that requires inconceivable quantities of electricity, aluminum manufacturer, iga wants to test the idea into by demand for aluminum. is that an all time high?

it's everywhere for mobile phones to airplanes. but production leaves a huge carbon footprint. medium is a very energy intensive process. wise, large amount of energy use one ton of to give you an example of we have a couple that'd be great and divide us and we are comparable. and what we utilize for our process, we have our own, kept to follow a plan, run on the natural gas. this, it makes a lot of carbon, which makes aluminum production, one of the biggest climate defenders. the main problem is in the blast furnaces, aluminum is smelt it from a gray powder called aluminum. using electrodes charged with electricity. just how much electricity can be seen here. we have

a very high very high i'm making just one ton of aluminum requires as much energy as a 2 person household consumes in 5 years. 15 megawatt hours since january 2021. this power hasn't just been coming from the gas fired plant. the factory is now linked up to the do by city grid green electricity to date, it's only enough for one percent of aluminum production. it's hopes that figure will gradually increase in the factories control room, the power supply is constantly monitored. a power outage would be

a catastrophe. lines to be jo, making on the menu come up this done result fall on for longer our. so it's like a bit to him. if this has stopped, everything is so total reliance on solar power is only going to be possible if this is available around the clock, including at night through storage technology, for example. this much is clear, green electricity can improve the carbon footprint of even the most serious climate defenders. the solar aluminum is all ready generating interest, even though it's more expensive than the regular kind. up to 66 percent of the customers clearly mentioned that they are willing to pay a higher price for a more sustainable product. but what even more important is more than 80 percent of the people said that responsible organization, as the see,

it must invest in environmentally friendly technology. in germany, several companies need no more convincing. the biggest buyer of aluminum from dubai is car maker bmw w. the aluminum factory and the desert plans to increase its consumption of green energy and to be climate neutral by 2050 the balloon invested. what's that got to do with climate protection? the, the answer, what's happening here is helping to cut concrete production. one of the world's biggest climate defenders mathias pizza, and as team from tj residents, technical university have been focusing on the metal framework. that's an every concrete walls. usually it's made out of steel here,

carbon fiber. this material has a very high tensile strength from front of you will steal as a tens of strengths of $500.00 newton per square millimeters. and then with this material like getting up to 3000 newton. when deans, if i can come out to the nation and consequently in comparison to steel, we can manage with much less material and save a great many resources as a result of the problem with concrete to make it need cement, extracted from ons, down the just here at the duke of health plan, it's fired at over $1400.00 degrees centigrade releasing huge quantities of c o 2. there is no way around it. but with carbon concrete, you can save

a lot of cement. this is because carbon doesn't rust. steel has to be protected from ross to by a 2nd layer of concrete. a carbon frame can be encased and a much thinner layer of the perfect, perfect, perfect, perfect lovely assessment. building with carbon concrete sometimes requires around half as much sum and then concrete reinforced with steel. that cod c o 2 emissions bye have the comparing to concrete themes see themselves also the i know it might look as though one is less efficient than the other one. the so is intensely, but that's not the case. and they're both equally strong guys. and paul, how do we just need more concrete to protect the steel from corrosion? so that's all there is to it. take all this being can be used in the same component, sparing the same weights as the steel concrete on the right side. to showcase its

possibilities. researchers are currently building the world's 1st carbon concrete house, the cube they say it'll last 200 years more than twice as long as a building made of steel concrete. the carpet may be much more expensive than steel, but less of it is needed which could ultimately even reduce construction costs, the concepts that are helping to ease the climate crisis still works. employee mohammed saucy and his sons have discovered something for themselves, eating less meat. it's important for climate protection is often underestimated. meet production generates more greenhouse gases, then global transport is as thickness shipping tonight by 8 may maybe once

a week and fish wants to wait on to me a bad. i'm not a vegetarian, but i'm increasingly eating like one be 10. we consolidate a vegetarian diet can save 450 kilograms of c o 2 every year. setting an example for the next generation says mohammed saucy was that can the and then on, on the, via the out children learn from us when we actually live by our own example. and they don't know if we lecture them and tell them what to do on the day of this i'm, i'm sure my children are also taking it on board off and that they'll live like this to be in the mail finds that it's young people who will be feeling the full effects of climate change. if industry is causing the greatest environmental harm act in a timely manner, perhaps those effects can be eased especially because it's really crucial that

college investments are old, channelled into climate neutral climate friendly concepts kind of thing. if we allow ourselves to invest perhaps also because of the current crisis in technologies that are geared towards achieving this, then it's a missed opportunity that won't come around again. so fast. the environmental offender industry could at one day be emissions free. it's a distant goal. but, and attainable one, the, the, the
