it is a very important thing of the term and in the fate of forty years of reforming and opening up has led chinese people to their moderately prosperous society and are becoming richer and richer we need to draw from this experience and continue to modernize the governance system of china the kurdish regional government in iraq has suggested freezing the results of its a session referendum which are going to confrontation with the central government the kurds say they're ready for talks with baghdad and they want to ceasefire iraqi forces are launching an offensive to recapture the last part of iraqi territory still and i saw hands they've been dropping leaflets warning civilians of the eminent assault i solicit for two major defeats in iraq in recent months after fierce fighting in mosul and how we chip the us is set to accept refugees again but with tougher vetting measures the top administration has ended a ban on new arrivals but people from eleven countries regarded as high risk by washington will be assessed only on a case by case basis the u.n. secretary general has praised peace keeper struggling to contain increasing
violence in central african republic and terrorist call their contribution heroic ceremony in the capital he told u.n. peacekeepers he appreciated their work extremely difficult circumstances but also warned fighting between religious groups could escalate into genocide they said the headlines news continues in al-jazeera after earthrise keep it or. the head of the september twenty fourth national election survey showed job and satisfied with the state of their economy this is easily the start his biggest tech success story the company was bought by microsoft in two thousand and eleven we bring you the stories that are shaping the economic world we live in counting the cost at this time on al-jazeera.
the composition of the air we breathe is changing. the sources of toxic emissions aboard around us. every year seven million people die from happening making it the world's biggest environmental community and that is the dire effects of global warming driven largely by an increase in greenhouse gases in the atmosphere. in twenty fifty one hundred ninety five countries signed the first comprehensive the keybinding pledge to reduce emissions. some countries are currently not following through on their promises but sounds like the commitment to finding ways to clean the air we breathe remains high. i'm going to robbie and fashion forward me a lot with the cement not only looks cheap but it also cleans the air and i'm russell bed and i think this is a one geothermal power plant they call their green credentials levels.
figures released by the world health organization show that eighty percent of city dwellers are breathing badly polluted air and this will only get worse as a society becomes more urbanized italy is one of the most polluted. countries in europe in two thousand and twelve it had the most pollution related deaths on the continent with over ninety thousand people in the country dying prematurely owing to bad air quality. like most european cities milan is highly polluted i've come here to meet a team of engineers who's created a product that could revolutionize unhealthy urban environments. well on a glamorous city famous for design and fashion has long been working on ways to combat its air pollution with architects looking towards buildings for solutions.
amazingly this incredible work of architecture is cleaning the pollution in the surrounding air as i speak and rico berger elo is the innovation director for the company that designed this building the pilot so italia this is amazing what a beautiful building these it combines the situation of the land one being. environmentally and also a very good investment and we have very proud to be able to come to. your attention . i swear i wash my hands. for you you can see this is a story in soon yeah we have the inside of the concrete that used. the. sunlight to reduce pollution the building is made up of cement that includes an active ingredient or catalyst called titanium dioxide. when u.v. rays hit the cement they react with this catalyst to break down pollutants like
nitrogen dioxide in the air. the toxic chemicals are turned into harmless products such as nitrates which are later washed of the building by rain and absorbed in the ground. so this really is a living building that's constantly interacting with its environment yes exactly when you have pollutants and they transform into hammerless products what kind of. illusion or are we talking about. the sun for. that one come from. so that's cars in the. industry these are all the major pollutants that can be destroyed by this what kind of impact are we talking about i mean how much pollution is being sucked from the air as we speak yes this is a nine thousand square meter of these concrete. this can. be going to exhaust gas from one hundred years in a car or almost three hundred from cars thought i think it's a significant impact and this is the impact of just one building. one
person who would greatly benefit from a city made of the cement is resident lara tournament. child of child she suffers from severe asthma due to the heavily polluted air here which is now affecting her mobility solera you are a true mill in these women you've lived here your entire life say only so. when did you first start to notice that the pollution in the city was really affecting your health queen vision if i inform each other that it probably may be this bit of your media is my the bottom key to. enjoy a good. list butyl be coming to milan machine to do the best the bad news. the job of course we can do you are you starting to hear of more and more cases like yourself. to look into the new you see it's
not just the elderly who are affected studies have shown a direct correlation between air pollution and as my children and across northern italy air pollution shortens the life of citizens by an average of fourteen months you need both in the bulletin this is the unknown. globally many more people now died early from pollution related diseases that from malaria each i.v. combined. massimo boresight is head of the innovation lab at. the company who makes the air cleaning cement. and i'm very nice to me where you thank you so much do i get to wear lab coat yeah. it's working with me think oh god i.
love to help but we are now preparing the material to fill this pan up on the floor of the material inside spinal ok let's see it happen to tell you are constantly experimenting with new ideas and distances. but experimentation doesn't always go to plan right here. over and that's where the mob i can help. them out so no offense or anything but i think this is a good time. oh ok. nice job. there it don't look look look look nice fella so this. is made of plastic yeah it's a plastic because so much. of the cement is able to heat. with plastics and to replicate them why does it need to be so smooth for two reasons first one for this that the christians the second one because mr freeze can reduce
the. piece of pollutants that remain untouched since a freeze on baking was stopped by the rain so if it was porous they would find their nukes and crannies to hide in with the smooth surface when it rains it just easily washes off excess you're right ok producing cement accounts for five percent of the world's car. dioxide emissions this project catalytic cement may produce the same emissions while being made but it reduces pollutants within a three metre radius by more than twenty percent. it's small games like this that can really make a difference and believe that this can contribute to the problems over the pollution for sure is not. i want to find out what proof the team has that this cement actually does clean the atmosphere this is a plastic this part of the time. has been. there for the six men
this is represent the sun and so when the light with. the sun reluctantly for the planet. and also in that. right. yeah. you can check that this number of the number looking you can muster this is monitoring the gas yes the limit without reaction is one hundred fifty thousand and ninety eight now because of the actual stuff to. decrease. as it's the u.v. rays that cause the reaction even on a cloudy day the cement is still reducing pollution look how much it gone down to forty percent of going down and then we are going to get the fifty percent over the auction approach but consider if that if you hold a fifteen percent of the town with his for the company tax man you continues the
fifty percent of the pollutants of the city he tells him and he may have come up with an innovative product but it is expensive one paving company has devised a cheaper and more practical application for it. the most and he has collaborated with it tell jim mentee and devoted an entire factory to the special cement. that. was. more annoyed. by the making for the company. that made the moros ok. last. just the fin layer of the photo catalytic material that's kind of to the surface of each time our you when. you come with me and i see my man show me your hands great massimo's invited me to visit
a health center where his brakes are paving the new car park. on this day don't. ya know that but he meant the photographer then the. technology that. well known for the name of but he didn't move the constructing photo catalytic paving this close to traffic the prime source of city pollution issues its effectiveness so here they are are all of these photo catalytic rest of the mental shit for the political. west above the mantel in a post to. lash out and i was one or two out of the lock to help ok. in fast forward. through those i ended up on and off on a photocopy to come in a. crowded room this is exactly like tetris i'm so glad i'm vested all those hours
as a child playing that video game. that. these are you know with the sidewalks in the roads that we walk and drive on all through our lives and this could have a massive impact on human health she. was the thing with the quote that even. the mental health care and the new york people eat or to even think of a lot of that on the. milan isn't the only city using this technology. from the new air force headquarters at shell the go airport to paving in chicago the application of this cement is on the rise. with innovations like this applied widely enough already been environments could become a lot healthier. countries
around the world are aiming for greener future. new zealand's investing haven't even uber any. particular height and it's a time of. costa rica's time is environmental dreams into reality running on renewable energy for two months and twenty sixteen. noways the first country to commit to the id for station and has plans to ban the sale of all fossil fuel cars within the next decade will bhutan is the only country to have succeeded in becoming fully carbon negative. entire country image just two point four million tonnes of carbon dioxide a year whereas forests. are three times that amount so we are a huge carbon sink and therefore i chose to use the word carbon. we don't have a choice but to come together as one world as one people
to address to the escalating threats of climate change it is urgent that we use the technology the wisdom the resources our combined resources to tackle this global problem once and for all. i say my love of the largest island in the world to cut carbon emissions unlikely environmental champion is part of the well above its weight. its unique role kind of doesn't just create. is unable one hundred percent of its electricity to be generated by renewable sources. much of which is juice or. ice and is the only country in the world to exceed this i'm here at the edge of the arctic circle where scientists are combining geothermal activity with
a new technology to try and help ice and become carbon neutral for good. so this is cute and couldn't. it's a very famous restaurant in these parts they apparently they cook on do with thermal energy and i've been told the kids is round the back. maybe everything's going to taste like i don't know. where it is. since i got. a low right it's only high how i welcome the life i've had thank you. thank you thank you only that we're seeing here yeah you're not boiling water this is steam that's coming yeah yeah yeah it's come from earth really and this area under here goes straight down into the ground yeah we're lucky we are warm up the building with ac power and the water in the sinks and everything and now we take
one more step into the actual use of the green powered we'll learn to make a food with it does not mean everything that you cook tastes like eggs. the smell of eggs stems from the sofa on the ground released with the steam to be crying in them if i might you know. this is good ice and one spoiled dependent start to use for new books after being hit by the oil crisis of the one nine hundred seventy s. hasn't back so we just had to open this years of assemble. the overlays like this. and now we are given the one hundred seventy so just steam coming in here in this pipe and then between here and now is start boiling already allow ten to fifteen seconds to boil i mean. that's fantastic as a business as free energy you got to love it i mean do you think about the environmental impact of your business afterwards i thought about not in the beginning yeah the purser thought in the beginning but after you think about it
maybe you do is a good thing maybe you're helping out the to save the world little bit and save planet you know maybe there's a lesson in that as well but it is doesn't really matter what motivation is about at the end of the day it is an environmental we're cycling and that's environment we have all of us have to think so but not be afraid with it you have to think of a. geothermal activity underground is also being used on a larger scale. this volcanic island of by salty grok is powering geothermal energy plants all over the country. with the capacity to supply all of the countries domestic outre steve hadley say the geothermal power plant is iceland's largest facility. ok so we're looking for a burka a sick person he said you chemist with i thought landing energy expecting us this
is going to be him i visit all the way. back and that's the media. and governors goes. here oh this looks never that. that's the sound of energy right i mean if they go on any other kind of power station whether a new. home or getting them needs a few well yeah. that was their right there was this being given that x. be better from the ground running from the ground here. by adding geothermal to their already advanced hydro capacity ice and became world leaders in renewable energy. basic question how does it you have some a plan where in very short but really whole into account and it really down to maybe two to three kilometers and there the steam is over pressurized and it comes by its own pressure through the production lines and we collect the steam of the
surface and then you produce power. just like that just like that to every be enough aids in the crust for millions of years to come we are only using kind of fraction of the heat that is being generated then the earth every day. the potential of this heat is so big the plans have been discussed for helping to supply the u.k. with geothermal energy from iceland. it might be fully renew but there is a downside in the process of accessing the steam naturally occurring gases like carbon dioxide in hydrogen sulfide are also brought to the surface. they found for a while there today i mean i'm never thin any color parts they feel like this before but of course when you compare it to more conventional kind of call our gas stations the emissions are absolutely minimal but there are emissions so we're
going to go meet another geoscientists here and he's going to talk to us about a really exciting new aspect of the project called carb fix. envy going to sin is a geochemist with conflicts it's brutal the kind of bad after it is going to let any of you thanks very good say this is that it will be better oh my gosh any pollutants emitted from the plant captured and sealed on the ground in the form of rock and we can tell through a car what is caught out thanks. how can she help through. the power plant you mean texting it back into the cell we want to do our part in. trying to solve this problem in trees conservation of see your point i. don't want to get stuck here. i guess is. really like another planet here. the gas emissions are transported from the main
energy plant via pipes to these geometric pods where they are rejected into the ground. i think worth a reason it has its voice and i see what i say. so why are we doing this well of all the labor this is what we call only injection well basically what comes from the problem once we have to do with. hot water and gas. we need to dispose of that somehow. if we would not be captured in the middle east ok ok and contributing to climate change was. re injecting the waste products of water and gas into the ground and abel's the carbon dioxide and hydrogen sulfide to permeate the volcanic assaulted rock and transformed into stone. and we have an example of that here a beautiful example of what the close to the rock fixing this you do. in these
rocks you how these cavities and each portion filled up with a couple millions you're turning the air pollution into the rock yeah. the car fix project replicates the natural process of weathering but instead of taking hundreds or thousands of years to turn into stone fix it in just six months. show me how successful the project is we first have to brave the weather again to take a sample of the gases which we can advance into liquid this is our miles. away this yr. in the dark i think we should just close of life gracefully getting medical. that can then. apply. and we have to have analyzed the c o two is for us
here. back in the lab the samples ready for analysis is to be injected gases have successfully turned into stone in the sample should only contain the naturally occurring background levels carbon dioxide h two s. or hydrogen sulfide ok here we have much of this you do and he and he had stressed this is a more sample of this unit because. we turn it on so what are you hoping to see here because obviously there is a background level of suit already what we are hoping to see that we see zero two levels in the city does not rise above the back on those ok here is the concentration of c o two in the sample and here is the concentration of hydrogen sulfide in the south which is about the same level as the back on close ok because
this. two storms watch. for me this is a very cool approach to lowering the gas emissions this isn't necessarily looked to geothermal energy is it that you have a relatively pure stream of shit to which you can capture this all in water then you can take that water and be interacting in the ground. long as you have favorable composition in your area. approximately five percent of the continents is possible. and then you have the ocean event which is all part of. my feeling is that more people should live. what company should be. or industry should do that. the potential is there when. people all over the world a dedicated to reducing our pollution. the innovations the device. powered by wind
alone the seven meter to dutch design tower in china sucks in the local smoke filled and compressing the particles of pollution to be recycled as jewelry. and american company has found a way to convert carbon dioxide into plastic pellets which are then used to build carbon negative furniture. and entrepreneurs in india have devised a product that captures ninety five percent of the harmful pollutants emitted from vehicle exhaust pipes this suit is then converted into a. form these technologies might be reducing pollutants in the atmosphere and with honey with financial and political commitment to producing clean energy atmosphere have a real chance. in colombia transforming urban waste into building long mean you just don't wear same clothes their waist plastic and your war they can finish their house in churches
you know to make up in just ten years and in singapore for it you go farms and living building anything you do on land on the ground it doesn't make sense to do that on a building you know can we make of not just decorative but can we make it biologically productive birthrights discovers cutting edge solution for sustainable city at this time on al-jazeera business update brought to you by cattle he always going places together.
