Global Air Pollution

Air pollution is a pressing environmental issue, causing serious health implications globally. According to the World Health Organization (WHO), exposure to ambient and household air pollution leads to 6.7 million deaths annually. In 2019, 99% of the world’s population was living in places with low air quality. A total of 4.2 million premature deaths were caused by ambient air pollution. According to the 2023 air quality report, only 10 out of 134 countries and regions achieved the WHO annual PM 2.5 standard of 5 μg/m3. Only 9% of the reporting cities succeeded in achieving the threshold set by the WHO. The global rise in GHG emissions plays a key role in increasing the concentration of PM2.5 air pollutants. Some of the countries with the most per capita carbon emissions are also the ones with the worst air pollution. 

On February 15, Reuters reported that the air pollution in Bangkok and the surroundings has reached unhealthy air quality levels. This can be attributed to crop burning, industrial emissions, and heavy traffic. The air quality of the city is 15 times higher than the WHO recommended value. The authorities are considering long-term solutions such as reducing fossil fuel vehicles and promoting EVs. This situation in Bangkok emphasizes the urgency for the worldwide adoption of eco-friendly practices. Integrating environment-friendly alternatives such as electric vehicles, sustainable fuels, and clean energy production is a crucial step to improving air quality.
