In rapidly developing urban communities, for example, Beijing and New Delhi, air contamination has turned out to be severe to the point that respiratory problems are increasing day by day, flights have been canceled, and the children are not allowed to play out. Chokingly thick covers of smog are a side-effect of financial development, which has increased the number of vehicles and more consumption of petroleum products, particularly coal. In the same way, countries all over the world are giving priority to tackling air pollution.

For example,

• Los Angeles offers a case of what urban areas can do to lessen contamination. Guidelines have been made where the vehicles and the fuel cleaners have effectively reduced the pollution, yet the city still battles with the issues of air quality.

• Paris has prohibited cars in many of the notable destinations at weekends. It has prohibited vehicles and is providing free transport to the public during the main events of pollution.

• The politicians of Netherland want to ban petrol and diesel from 2025 onwards. It wants to permit electric vehicles only. The new law would permit any individual who as of now possesses an oil or diesel vehicle to keep utilizing it.

• Oslo intends to divide its atmosphere outflows by 2020 and it has proposed a no-vehicle zone, creating lanes for bicycle, soak blockage charges, a surge hour expense for drivers, and evacuation of many of the parking spots.

• Zurich has topped the total count of parking spots in the city. It just permits a specific number of vehicles into the city at one particular time and is constructing more vehicle free zones, cable car lines, and pedestrianized lanes. The outcome has been a significant reduction in traffic congestion, and less contamination.
