How megacities around the world are tackling their air pollution



Air pollution kills millions each year, especially in the world’s megacities. But we found some surprising news: In many places, it’s actually getting better! Here’s how megacities around the world are already making their air cleaner and safer.

We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we’ll take a truly global look at how to get us out of this mess.

  1. There aren't that many trees in my city, and the government has no plan for the development of mass transit railways. I've been to Singapore, Thailand and Hong Kong, I always thought when are we going to have those.

  2. Where are the bike roads in Pune. I stay there, cycle more than drive (6000 kms cycled in 23 and 1500 kms driven) and there isn’t 1 km of usable cycling road. Come cycle with me and show me cycling infrastructure. Don’t go by theoretical data. Also the Pune air quality is bad because of garbage burning that smoulders through the day.

  3. It is great to see more and more cities as well as people taking air quality more seriously. Here in India, we are seeing huge investments in the renewables sector, which is a great thing. One of the future problems that I see is the fact that our railways, which is one of the best ways to travel in the country is heavily subsidised for passengers and it makes up for those costs through freight customers, the largest customers of Indian railways are the coal producers who transport coal to the power plants, with the reduction of demand in coal the railways will also see a reduction in revenue. That means the cost for passengers might increase, discouraging people to use the railways in a price sensitive economy like India.

  4. this is the most delusional report I have seen till date from DW, cherry picking specific initiatives that will never reach scale and and taking work on done on paper as if the tthey have already completed the project and we no longer need to worry. Cities in the developing world will have to see it getting much worse before getting any better.

  5. Generally, most electricity comes from Coal based plants ,& those Lithium based batteries are Polluting our Environment more than diesel vehicles by digging Lithium from mining sites 😂

  6. For the past 1-2 years after the pandemic subsided (after january 2022), I have seen several electric cars, bikes and most noticably electric buses by the transport department. I am talking about Kolkata. I hope my city would see more of electric vehicles and the expansion of green public transport and solar power instead of coal power plants.

  7. In winter, most of the areas of North India get polluted. The whole of North India needs a solution for this. By making artificial rain in Delhi, we can reduce it for some time but it need permanent solution.For this we will have to make a good long term plan by which pollution can be controlled.Pollution control in Indian cities: You can see how much pollution is in your area in Google Map.

  8. I'm sorry but Calcutta making an effort…..? It's far away from anything which says decarbonisation, improve live quality for its citizens or reducing pollution. Best thing it can do as starters is free up footpath so people can walk to start with.

  9. Most people do not need cars in cities, and ones who really do must drive EVs. We must focus on walkable cities with large sidewalks with trees, with secured bicycle lanes, with electric public transportation (metro, tramways, trolley-bus, electric buses) within cities and trains between cities. Cars are welcome in cities, but only zero emission cars, and they must be the exception to save space for better alternatives. And of course street parking must end in dense cities, space is too valuable to just park a car. It will not be done in one day, so we must start today.

  10. there are videos from india which show people spraying mist around these sensors to lower the AQI, my PM1006K sensor had crossed 1000ug/m3 mark on the Diwali night(its a festival) vs sensors in the city showed around 150ug/m3, i verified the readings with all my air purifiers all of them were above 600ug/m3

  11. These are the following things which i would like to see government doing-
    1) Increase GST and VAT on luxurious vehicles, ordinary cars also so that we can demoralise people buying these carbon emitters also encourage people to use transports than their own vehicles.
    2)If government really cares about people(Although they don't) then they should give financial aid to such people who are currently
    living below the poverty line and are currently registered to PM UJJWALA scheme by using DBT (Direct benefit transfer).
    3)Government should encourage influential people like-Shahrukh khan, Salman Khan, Amitabh Bachan to endorse cycles and
    government officials should use bicycles like we see in Japan.
    4)In order to tackle stubble burning government should give more incentives to millets than rice crops this will not only discourage
    farmers to grow rice crops but also it can help to tackle the ground water issues.
    But unfortunately we don't have such governments who actually listen to people but these bastards are busy filling their pockets for upcoming
    elections and dividing people on caste ,religion and sect.

  12. I came of age in So Cal during the 50's and 60's when we had some of the worst air pollution in the world. The state government took action with pollution control standards even more stringent than federal standards and solved the problem within a decade. Air pollution experienced by children results in 10-15% less lung function in adulthood than children who live in cleaner air.

  13. In my city there is a cement factory that produces a lot of pollution, both in terms of particles and smoke due to the kilns. There are some oddities, for example, the factory is legally located in another district (although territorially it is here), that is, the pollution is all in our region, but the taxes go to another city. Secondly, they already have a smoke filtration system, but they don't care, they say high energy costs. Politics does nothing, it covers up irregularities and it will probably be like this for many years to come. I no longer have hope in humanity, the vast majority are just trying to make a profit, thinking that none of this affects them directly. I hope we are the last generation alive.

  14. I live in the middle of amazon forest in Brazil , we are facing threatenings levels of air pollution coming from forest fires made by illegal farmers that creates cows. And almost nothing is being made to stop the forest fires by the local authorities, even the federal government isn’t doing much to match what is being burned. Some days we are at the 10 worst air quality in the world

  16. Good to hear that Krakow and Warsaw were mentioned in the video. Kraków had and still has a polluted air. Local government decisions helped to reduce air pollution by eliminating solid fuels in city (45000 furnaces removed). Right now City hall granted money to areas around city boarders to eliminate even more solid fuel furnaces. Last but not least new policy is on the way to reduce older cars from entering the city. There are also multiple other examples how the Krakow wants to reduce air pollution. If you ever wanted to spread fresh ideas please create a video only about my city 🙂

  17. the one german mega city, the ruhr area, meanwhiles poison his population, wile the public transport system is a joke and the cdu in essen supress the data of sensors near the a40, probably putting essen to one of the 20 most polluted cities on the planet.
    germany is a joke.
