the composition of the air we breathe is changing. the sources of toxic emissions that will round us. every year seven million people die from happening and making it the world's biggest environmental community and that is the dire facts of global warming driven largely by an increase in greenhouse gases in the atmosphere. in twenty fifty one hundred ninety five countries find the best comprehensive legally binding pledge to reduce emissions. some countries are currently not following through on the promises but elsewhere the commitment to finding ways to clean the air we breathe remains high. i'm going to robbie and fashion forward the laws for 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 was being. environmentally and also very good investment and we have very proud to be able to contribute three touches. i swear i wash my hands. for you you can see this is a three and soon to start yeah we have the inside of the concrete that used. that allows 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 are transformed into ham products what kind of. lucian are we talking about. the sun for. that one come from combustion so that's cars. 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 taught 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 dish on a five inch i believe it probably will be displayed at sea or media smart the bottom key to. enjoy a good place beautiful only to milan machine to do the best the best. so the job of course we do know though are you starting to hear of more and more

cases like yourself. to look into the one you use and 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 die early from pollution related diseases than from malaria and h.i.v. combined. massimo borsa is head of the innovation lab at you tell jim n.t. the company who makes the air cleaning cement. i'm very nice to me where you are thank you so much do i get to wear lab coat yeah.

that's working with me think hello oh. buck stops with me right now the thiering or the mafia to fill this panel on the floor of the material inside spinal ok lets it happen. to you are constantly experimenting with new ideas and distances. but experimentation doesn't always go to plan right here at. home and that's where the mob i can help. that's when i cannot act so no offense or anything but i think this is a good time. oh ok. nice job. there i don't look look look look. so this. is made of plastic yeah it's a plastic because so much you know it has to be smooth and the cement is able to read. 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 the phrase can reduce. piece of pollutants that remain untouched since a freeze and baking was stopped by the rain so if it was porous they would find the will 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 carbon dioxide emissions this push a 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 might you know can contribute. to solve the problems over the pollution for sure is not only his material but yes it can contribute to what 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 town is being coated thanks man this is represent the sun and so when the light with. the sun and we like to be at the front of the team and we also in that. inside. let's check it out. you can check that this number of the number of mr this is monitoring the gas yes the limit without any reaction is one hundred fifty thousand and ninety eight now because of the actual stuff. done to degrees and. 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 which is for. you continues to fifty percent of the pollutants of the city he tells you meant 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. in mexico city has collaborated with to tell jim mentee and devoted an entire factory to the special cement. of a man. with. more noise. and more moros ok. last. just the fin layer of the photo catalytic material that's kind of to the surface of each time now you would. know you come with me here and there

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 and the. technology that. so putting them up but if you don't move the constructing photo catalytic paving this close to traffic the prime source of city pollution ensures its effectiveness so here they are are all of these put a catalyst like crystal grip of the mantle shit for the political give you no. quest upon the mantle inapposite to. lash out of it and i'm sure not to out of the lock work to help ok. then in fostering you through the phone but ended up i mean that's when a photocopy in

a white. no this is exactly like tetris i'm so glad and us that all those hours as a child playing that video game. that. these are you know the the sidewalks and the roads that we walk and drive on all through our lives and this could have a massive impact on human health. because nobody even. the mental health care and the new york people eat or. i go for water that on the. mainland 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 green future. new zealand's investing heavily on uber energy taking hikes 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. huge carbon sink and therefore i used 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 said my novel the largest island in the world in the fight to cut carbon emissions unlikely environmental champion is punching well above its weight. its unique role can exceed origin doesn't just create taking siri is unable one hundred percent of its electricity to be generated by renewable sources. much of which is to say. iceland is the only country in the world to the cheaters 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. this is cure and couldn't. it's very famous restaurant and its parts they apparently they cook on do with their more energy and i've been told the kitchen is round the back. well. maybe everything's going to taste like egg i don't know. it is in essence like i. had no right i only heard how i welcome the life i had 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 hole under here goes straight down into the ground yeah we are lucky we are warm up the building with this heat 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 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 able to pry open them if i might your right. to this is good i sent one spoiled dependent start to use for a new bush after being hit by the oil crisis in one thousand seven hundred hasn't it back so we just had to open this year's survey sample. the oval is like this. and now we are given the one hundred seventy or so says steam coming in here in this pipe and then between here and now i start boiling already allow ten to fifteen seconds to boil i mean that's fantastic as a business that is free energy you got to love it yeah i mean do you think about the environmental impact of your business afterwards i thought about not in the

beginning yeah the person talking the beginning but after you think about it maybe you do is a good thing maybe you're helping out to save the world little bit and save the planet you know maybe there's a lesson in that as well that is doesn't really matter what motivation is a mother at the end of the day it isn't environmental we're cycling and that's an environment we have all of us have to think so big. not be afraid of it you have to think so but. yeah. geothermal activity underground is also being used on a larger scale. this volcanic island of by sol take rocky's power and geothermal energy plants all over the country one. with the capacity to supply all of the country's 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 floundered energy expecting us this is going to be him i visit all the way. back and as a media. outlet and others go cause. holy smokes never that. that's the sound of energy being really right i mean it's very very low on any other kind of power station whether with nuclear. hole or god and everything it's a few well yeah when he was there and there was this being given that i guess being better at it from the ground i ran it from the back yard. 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 anybody shorts it in the hole into account and we three 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 this theme of the surface and then you produce power. just like that just like that but every be enough aids in the crust for millions of years to come we are only using kind a fraction of the heat that is being generated then the earth every day. the potential of this he 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 and hydrogen sulfide are also brought to the surface. i thought for a while the other day i mean i've never seen any color power station 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 missing that 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 card fix. envy going to sin is a geochemist with cox fix. it's brutal and. after it is always ready you thanks very good say this is that it will be better my gosh any pollutants emitted from the plant captured and sealed on the ground in the form of rock and we can tell it's about corporate what is copper out thanks. to. the power plant means that they get back into the ground we want to do our part in trying to solve this problem the interest conservation and she has been. don't want to get stuck here. i guess is going to.

really use like another planet here and pass the gas emissions are transported from the main energy plant pipes to these geometric poets where they're rejected into the ground. and i think that will the some reason it has the smallest myself what is it yeah. so we do it and it's wonderful almost like good this is what we call our reinjection well basically what comes from the problem once we have to do is to just be hot water and gas and we need to just. also. if you would not be captured in the middle east ok ok and contributing to climate change what. re injecting the waste products of water and gas into the ground and able to carbon dioxide and hydrogen sulfide to permeate the volcanic of the soul to rock and transform it into stone. and we have an example of that here bit of an

example of water flows through the rock fixing this huge tree in these rocks you have these cavities and each pause filled up with a couple millions you're turning their pollution into the rock. the carfax 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 a vital part of the way this year for. life in the south i think we should just close a lot right now and getting very good you can feel the heat that can then.

apply. and we have to have analyze the c o two is for us here. back in the lab the samples ready for analysis if the rejected gases have successfully turned into stone in the sample should only contain the naturally occurring background levels carbon dioxide it's to us or hydrates over here we measure this year doing the and yet yes this is a what's up with you that we collected. and we turn it on so well. you hoping to see because obviously there is a background level of suit you already yeah what we're hoping to see here is that we see zero tolerance in births the does not advisable or back on those ok here is the concentration of c o two in the sample and here is the concentration of high the fight in the south with says about the same levels as the back on those ok the

garces to two stops to watch. for me this is the word cool approach to lowering the gas emissions this isn't necessarily looked to geothermal energy is it long as you have are relatively pure stream of c o two which you can capture this all been water then you can take that water and be injected into the ground are so long as you have favorable composition in your area. approximately five percent of the continents on earth is possible. and then you have the ocean event which is all because of. my feeling is that more people should look. more companies should do. more interest we should do that. the potential is that. people all over the world are

dedicated to reducing our pollution. innovations advice. powered by wind alone the seven meter to dutch design tower in china sucks in the local smoke field and compressing the parts because of pollution to be recycled as jewelry. and american company has found a way to convert carbon dioxide into plastic pellets which is 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 the suit is then. infects and contained. these technologies might be reducing pollutants in the atmosphere and honey with financial and political commitment to producing clean energy. atmosphere and have a real chance. and
