An analysis of global air pollution trends reveals notable progress in several nations, especially in reducing PM2.5 particle pollution.
Global Air Quality Trends: A mixed Bag
A recent report by IQAir, analyzing data from over 40,000 air quality monitoring stations across 138 countries, highlights a diverse range of air quality trends. while some nations grapple with worsening pollution, others have made remarkable strides in improving thier air quality.
Countries in Central and Southeast Asia, along with Eastern and Southern Europe, have shown the most considerable improvements in air quality since before the pandemic.
Mongolia‘s Remarkable Progress
Mongolia stands out as a leader in air quality improvement. Between 2019 and 2024, the country achieved a reduction of more than 30 micrograms per cubic meter in average annual air pollution from particles 2.5 micrometers in diameter or smaller (PM2.5). This places Mongolia at the top of the list for air quality improvement.
Despite the continued use of coal-burning stoves,especially during winter,programs aimed at helping poorer residents switch too electric heating have yielded positive results. This significant improvement has allowed Mongolia to nearly reach the WHO interim goal 2 out of 4, bringing them closer to the ultimate target of an average annual PM2.5 pollution level of 5 micrograms per cubic meter of air.
Indonesia’s Efforts to Combat air Pollution
Indonesia, particularly its capital Jakarta, has long been associated with significant air pollution. however, recent efforts have led to notable improvements. While Jakarta ranked as the seventh most polluted capital in the world in the 2023 IQAir ranking, it dropped to tenth in 2024.
These improvements are attributed to advancements in cooking fuels and enhanced pollution controls on transportation and industry. Despite these positive steps, Indonesia still narrowly missed WHO interim goal 1, highlighting the ongoing challenges in achieving cleaner air.
gulf Countries and China Show Promise
Bahrain exemplifies the progress made by several Gulf countries in addressing air pollution. As the region increasingly regulates fossil fuel use, Bahrain achieved WHO interim goal 1 for the first time in 2024.
China has also demonstrated consistent improvement, meeting the first WHO target since 2020 and ranking as the 11th most improved country in 2024. However, the situation in India remains critical. While India’s growth was among the 20 best globally, its pollution levels are considerably higher and still far from meeting international targets.
Europe’s fight Against Household Pollution
european nations such as Kosovo, Bulgaria, and Greece are also among the top 10 most improved countries, reaching as far as interim goal 3. A significant contributor to pollution in these countries is the burning of wood and coal for heating by private households.
This issue was particularly pronounced in 2022, when energy costs surged following Russia’s invasion of Ukraine.
India’s Air Pollution Crisis
The World Air Quality Report 2024 reveals a concerning situation in India,with the country ranking among the top 5 most polluted globally. The report indicates that 13 of the world’s 20 most polluted cities are located in India.Byrnihat in Assam is identified as the most polluted city worldwide, while Delhi remains the most polluted capital.
