Join us for an exciting exploration of everything in between. This is a video and audio production 5 d w. I hope video will tune in from delhi to is bundle to los angeles. Evolution is a big issue, especially in the worlds biggest cities, between decrees or long function, it will increase. Thats not that its an increase of space in the emissions warranty. Due to 7000000, theres a u. C o, these pink dumps. They show that in almost every major city in the world, the air is found that he has some of the World Health Organization consider safe. When we dont into the data though, we found some surprisingly good news. In many megacities see here its getting better. So we wondered, what are the city is doing right . And can replace due to the for this analysis, we looked at one measure of evolution, thats everywhere. P m 2 point 5, pm, 2 point 5 pm. Youll find 5 pm, 2. 5 kids 2. 5, p. M stands for particulate matter and make sure studied particles and liquids dropped instead of 2. 00 microns for less, much smaller than a human here. This is only one possible type of information about peoples lives. If he could meet from the w h o, use it as an indicator for evolution in general to this is important that can come from very different sources. And he tried to do because this seemed to work to it. There is really no place in the world that is the trio service or to get his mentor. And its big cities that are often particularly polluted. This problem has been well known for years to sign up with anything has changed. We took a closer look at this state domains from the Swiss Company i q, and we chose average levels of pm to point 5 for more than 7000 cities. Over the past 5 years, we put it all into a big excel spreadsheet and check that against a list of the worlds biggest cities. Those has more than 10000000 People Living in them. Of those 25 cities, it seems like the air has gotten better in all of that. Even when levels are still high. What weve seen is that on average, about 5 percent improvement in air quality over the past few years. So we chase help cities that want to tackle the air conditioning problems. The causes are similar even when the proportions, very transportation emissions are often number one, not always but. And then also just generally electricity use people cooking with solid fuels and their homes and some parts of the world heating was solid fuels. Another major source of air pollution is from industrial sources and then also from weight. So hits what city is that doing to tackle these issues for many cities changing how people move around just can make a big difference here. So freaking me from the w h o again. There was a need to be a push to really have peter rachels, but also fewer legal reading from on the working side team. And the, providing most of the transportation was effectively the electric very, to take bank coke. For instance. The city is working on expanding its Still Limited skytrain and metro services. And in the meantime, electric alternatives for the traditional Combustion Engine topics that people going around emission for you as well. Denny is working on an extra fine, 80 percent of his bus rates, and even in coca town, sometimes called the diesel capital of the world. A tentative like this electric Scooter Service starting up the next steps. So which i says can be introducing so called low emission zones cities that are restricting emissions in a certain part of their city both to improve their quality, but also to improve quality of life. This might mean only allowing clean a cars to into or no cars at all. And it might mean transforming speeds to make more room success trans, or by sickness. This is something thats resonating across all regions of the world right now. Thats really exciting from times square in new york city, being competitive with this through an area to reducing traffic and compound or below horizontal to more by planes and parents are putting cities everywhere, experimenting with a different kind of urban design transport is not the only area such as must tackle there is extra time against air pollution also focuses on Industry Measuring and reducing the task from construction sites and having more industry shift to clean up fuels and more efficient techniques that converging traditional brick accounts to 6 atkins. This is something a lot of cities are doing like here in the heart process done. The method still uses cold, but much less of it and attracts more of the particulate matter inside the account, knowing its emissions. One reason for that is lucky, but uh the space might be that in 2018, the city shut down the by the pool coal tall trend, which also comfortable for around 10 percent of the cities particulate matter. Air pollution are known one area that progresses still snow is waste to there to have you Solid Waste Management vinyl from 2016. This to not implemented by reading category has been advocating for clean air for more than 20 years. She found at the mothers active as group worry, a moms who campaign against evolution by petitioning the government and courts throughout india. She says, even when the right policies are that the government often doesnt follow through, we do not segregate the ways to source. And mostly its all makes. And that is what is making those huge landfills and the mixed race to insinuated in the middle of a city without organized waste connection funding is awesome. The only option for getting rid of unwanted materials causing toxic smoke full of handful particulate matter that can stretch for miles. So preventing waste as well as collecting and disposing of it better has to be part of any cities time to curve and pollution. When policies are implemented thoroughly that can have a big impact take facing, for instance, a decade ago, it consistently made headlines for its toxic smoke cover. But in the last few years, it has massively produced its pollution levels. And its not just beijing, many of chinas mega cities have improved a lot recently. This is the result of what the Chinese Government pulls a war on air pollution. Thats focused on the clothes as weve already mentioned, but not least on energy and how people cook and heat the homes. The city of phasing and polls type limits on emissions from boy thats used in peoples homes and subsidized anyone who wanted to upgrade that coal fired boiler to natural gas, which is still a fossil fuels, but produces much less particulate matter or to electricity, which could be produced by renewables. Studies show that the 20 percent of the reduction in beijings pollution just came from renovating these cold pile going us outside of china as well. Countries around the world are investing in renewable energy, phasing out cold from the Energy Supply in favor of solar, wind, and other countries like poland are also getting rid of the coal and wood fired stones. And sol in south korea, which already swept coal. He does for gas, back in the 19 ninetys is now discussing the switch to more eco friendly heat funds for cooking stove fires with wood or kerosene activity on the option in many parts of the world, especially in rural areas, without access to electricity such as projects from pakistan to rhonda to the millions or introducing cleanest of models to those regions as well. Whether and how 5 cities can implement change comes down to a few things. And the 1st total is bits of data. Take the hort, impact of some irregular the top solice of the worlds most polluted cities. According to the data, it looks like it has improved at least a little. But its hard to say without any actual changes happened. We havent really seen any trends that would explain why the numbers are going down. So i think its just that the, the quality or data improve is not beat on march 2016. He found as a pockets on eck, one of the initiative, which is a community initiative, a life i ended up individuals. Corporations, organizations have come together with low cost monitors and providing that data. A public lea uh on the internet on base that farms that data is what is driving awareness impact of some there are very few equities you want us to set up by the government. This makes it hard to judge with that. Things are actually getting better. Thanks to its initiative. So there are no more than a dozen sensors in the for a long showing the current air pollution levels, making it harder for governments and citizens take northeast and monitoring systems, a strong up everywhere in the past few years. To these are increasing their ability to monitor their air quality, and this is something that is extremely important. A very positive trends from our perspective. Then thats the question of money. Changing was able to put a huge amount of investment into the air quality problem. And that is the key question for a lot of other cities right now. Do they have the money to invest, to make such a step change in their air quality . And last but not least benefit digital collaboration. So if you imagine air flowing together over parts of the world, thats what we call in the air shot and it doesnt respect political boundaries and found a place like deli, its extremely important, but neighboring cities and jurisdictions Work Together on their common problems. Cups of learning brings in 10 small to now that india, including daily every year after the hottest season. And the same problem happens, for example, in cairo or across indonesia where smoke cells can reach so far, they fix the air and singapore and parts of malaysia. So cities, regions, and countries will have to Work Together to change because of what we have at the heart of the matter is the health of the People Living in a city. It doesnt really matter where the air pollution is coming from. Its extremely important that its reduced. So evolution is still a huge issue. Big cities all over the world are pretty far from what the w h l consider safe, which would be below 5 microphones per cubic meter of it, but it can get that time. So thats a tell people that they get this so disciplined us a fixed its, its taking me a decade, 0 for us. People like us to be fighting the field and the gods and coming such a long re changes happen. So theres some changes in the v and even when really good air as far away, any change helps in the reduction. Includes crowns, and its more reduction is good. Whats more is that the things that clean up there are also good for combating climate change, which is likewise fueled by emissions from burning waste and fossil fuels.
