TLDR

  • Seoul's air quality has significantly improved over the past 20 years, with fine dust and ultrafine dust concentrations decreasing by approximately 40% and 47% respectively.
  • The reduction in air pollution is attributed to the shift away from diesel vehicles, the introduction of eco-friendly buses, and stricter management of emission sources.
  • While air quality has improved, Seoul is focusing on managing ozone levels during the summer months through targeted inspections and public awareness campaigns.

Seoul's air quality is breathing easier, a testament to sustained environmental policies and a city-wide commitment to cleaner transportation. The significant reduction in ultrafine and fine dust over the past two decades, as highlighted by the Hankyoreh, showcases the tangible results of transitioning away from a diesel-dependent vehicle fleet.

The average annual concentration of ultrafine dust has decreased by about 40% from 30ใŽ/ใŽฅ in 2006 to 18ใŽ/ใŽฅ in 2025, and fine dust has also decreased by 47%, from 60ใŽ/ใŽฅ to 32ใŽ/ใŽฅ.

The city's proactive approach, including phasing out diesel buses in favor of eco-friendly alternatives like hydrogen buses, and implementing measures for older diesel vehicles, has directly contributed to this positive trend. This focus on mobile emission sources, coupled with efforts to control stationary sources like industrial facilities and boilers, demonstrates a comprehensive strategy for tackling air pollution.

The transition from diesel buses to eco-friendly vehicles and the expansion of electric bus adoption have reduced mobile source pollution.

While celebrating this environmental milestone, Seoul remains vigilant. The ongoing challenge of ozone pollution during warmer months requires continued attention. The city's plans for targeted inspections of volatile organic compound-emitting businesses and enhanced monitoring of vehicle emissions underscore a commitment to addressing all facets of air quality. This dual focus on past successes and future challenges reflects a mature and responsible approach to environmental governance, a perspective often appreciated by citizens who directly experience the benefits of cleaner air.

We will operate a high-concentration ozone season management plan from this month to August, inspecting 1,030 businesses that emit volatile organic compounds.
