Seoul: A recent analysis by the National Institute of Environmental Research, conducted in collaboration with NASA, has pinpointed China as the primary source of Korea's recurring ultrafine dust problem. Released last month, the study revealed that approximately 55 percent of Korea's PM2.5 particles originate from China, overshadowing the 29 percent attributed to domestic sources.
According to Yonhap News Agency, the Korean government has set ambitious goals to combat this issue, aiming for a 2 percent cut in ultrafine dust and its precursors this year. This involves reducing total emissions to about 129,000 tons and lowering national average PM2.5 levels from 20 to 19 micrograms per cubic meter. Despite Korea's commitment to these targets through stringent regulations and public cooperation, the effectiveness of these measures is limited by the significant influx of pollutants from China.
Korea has emphasized continued cooperation with China, focusing on sharing forecast data, exchanging policy measures, and coordinating alerts. However, the editorial from The Korea Times suggests that such collaboration is insufficient. Korea needs to demand accountability from China, which has shown the capability to enforce strict emissions controls during major international events. The editorial argues that if China can clean its skies for such occasions, it can certainly take steps to mitigate the spread of pollution across its borders.
The editorial also calls for Korea to address this issue as a matter of regional public health and environmental justice. It suggests demanding concrete action plans from China, including targeted emissions reductions from industrial zones affecting Korea. Additionally, Korea should explore compensation mechanisms to recognize the environmental, medical, and economic costs imposed by China's pollution.
Critics may warn of potential diplomatic tensions, but the editorial emphasizes that inaction carries a greater cost. Koreans bear significant expenses for health care, air filtration, and protective measures due to poor air quality. The editorial concludes with a moral imperative: when over half of Korea's PM2.5 is sourced from China, any solution that fails to address this is inadequate. It advocates for a move beyond mere courtesy to accountability, compensation, and coordinated regional action to safeguard the health of the Korean population.
