Air pollution is taken into account to be essentially the most pressing environmental problem of our time, causing 7 million premature deaths annually. Nine out of ten people all over the world breathe polluted air, which increases their risk of lung cancer, heart disease and asthma.
City dwellers, especially the poor, often experience the worst effects of air pollution, which not only threatens lives but in addition fuels climate change. Many cities, aware of those threats, are taking motion to combat air pollution.
The study examined five of those sites ahead of the annual International Clean Air Day for Blue Skies on September 7, highlighting the urgent need to enhance air quality.
The data from www.iqair.com which states that an AQI (Air Quality Index) level of 0-50 is sweet and a level of 300+ and above is harmful, is the premise for the sources given below. The EPA AirNow rating is different from the worldwide air quality tracker IQAir, which uses information from sensors along with official data from the EPA, UN and other sources.
Seoul, South Korea
Surprisingly, the most effective city is Seoul, South Korea. Greater Seoul is home to 26 million people, so it’s no surprise that the town is experiencing an air quality crisis. In fact, in comparison with other members of the Organization for Economic Co-operation and Development, Koreans have the very best average exposure to the deadly particle referred to as PM2.5.
PM2.5 concentrations in Seoul are roughly twice as high as in comparable large developed cities. The city has declared that by 2025 all fleets utilized in the general public sector and public transport will likely be freed from diesel vehicles. This collaboration with the United Nations Environment Program (UNEP) will explore the knowledge gained over the past 15 years on improving air quality and help disseminate this data to other cities in the world.
Bangkok, Thailand
The best city with the cleanest air in Southeast Asia is Bangkok, Thailand. Considering Bangkok has a few of the worst traffic on the earth, it isn’t surprising that the town often struggles with a layer of smog.
Due to dangerous levels of air quality attributable to advantageous particulate matter, or PM2.5, a whole bunch of colleges were forced to shut in 2020. The city has launched a lot of programs geared toward combating carbon dioxide emissions and air pollution.
Launched in 2019, the Green Bangkok 2030 initiative goals to cover 30% of the town’s total area with trees, increase the quantity of green space per person to 10 square meters and be certain that sidewalks comply with international standards.
In the primary phase of the project, eleven parks and a 15 km green trail will likely be opened, encouraging people to limit using private cars and reduce pollution.
More countries are adopting incentives or regulations to advertise cleaner production, energy efficiency and industrial pollution reduction, in line with UNEP’s 2021 Air Quality Action Report, while regulations prohibiting the incineration of solid waste are also expanding. But there remains to be much to do.
Only 31% of nations have a legal framework to regulate or combat transnational air pollution, and 43% don’t even have the concept of air pollution of their law. Most countries still don’t have a reputable framework for managing and monitoring air quality.
With greater than 90% of air pollution deaths occurring in low- and middle-income countries, mainly in Africa and Asia, inequality can be a contributing factor to air pollution. Richer areas are less exposed to air pollution, even in cities, than poorer areas.
