Ukraine was 8th in Europe and 43rd among countries in the world in terms of air pollution in 2020, among the world capitals Kiev was in 39th place in terms of air pollution with small particles.
The 2020 World Air Quality Report includes data for 106 countries, up from 98 countries in 2019 and 69 countries in 2018.
The report is based on the world’s largest database on air pollution by fine particulate matter PM2.5. Much of the data comes from government air monitoring stations, but the network of non-government monitors is also growing.
According to these data, the regions of South and East Asia remain the most polluted in the world. Bangladesh, China, India and Pakistan have 49 of the 50 most polluted cities in the world.
Air pollution in the world during the covid-19 pandemic
The COVID-19 pandemic and lockdowns have led to a decrease in air pollution. In 2020, 65% of the world’s cities received improvements in air quality compared to 2019, 84% of countries had overall improvements.
2020 also saw some extreme air pollution from wildfires and dust, storms associated with rising global temperatures, and agricultural practices.
Over the past year, air quality has improved in major cities: Beijing (-11%), Chicago (-13%), Delhi (-15%), London (-16%), Paris (-17%) and Seoul (-16%) ).
Ukraine’s indicators have worsened over the year: in 2019, our country took 60th place, and in 2020 – 43rd; among the countries of Europe in last year’s report, Ukraine was 13th, and now 8th, and Kiev among the world capitals was in 49th place, and now on the 39th line in air pollution.
Air pollution worldwide and their causes
In Europe in 2020, about half of the cities exceeded the WHO’s annual PM2.5 pollution target. The highest levels of PM2.5 pollution were found in Eastern and Southern Europe; led by Bosnia and Herzegovina, North Macedonia and Bulgaria.
In the United States, average particulate matter pollution rose 6.7% in 2020 despite measures to contain the spread of COVID-19. Record wildfires in California; Oregon and Washington DC ranked U.S. cities as 77 of the 100 most polluted cities in the world in September 2020.
In 2020, 38% of American cities did not meet WHO guidelines for annual PM2.5. This is a significant increase from 21% in 2019.
In India, air quality improved in 2020 compared to 2018 in all cities, compared to 2019 in 63% of cities. Nonetheless, India remains at the top of the list with 22 of the 30 most polluted cities.
In 86% of Chinese cities in 2020, the air was cleaner than the previous year. Despite this, people in China are still exposed to PM2.5 more than 3 times the annual WHO guidelines. Hotan in northwest China is the most polluted city in the world, mainly due to sandstorms.
Only 24 of the 106 monitored countries have met the World Health Organization (WHO) annual PM2.5 guidelines in 2020.
