How technology boosts Beijing's air pollution governance_我的网站
一 |
In 2025, Beijing recorded 311 days with good air quality and only one heavily polluted day, compared with 58 heavily polluted days in 2013, when the city officially began releasing PM2.5 monitoring data. The annual average PM2.5 concentration, a key indicator of air quality, fell from 89.5 micrograms per cubic meter in 2013 to 27 micrograms per cubic meter in 2025, a decline of nearly 70 percent.
The progress has drawn international attention. The United Nations Environment Programme has highlighted Beijing's experience in improving air quality as a model for other cities.
According to experts at the Beijing Municipal Ecological and Environmental Monitoring Center, the cleaner air is the result of a comprehensive system integrating environmental monitoring, scientific analysis, policymaking, regional cooperation and law enforcement -- with digital technologies now woven into every link of that chain.
MORE TARGETED APPROACH
Effective governance begins with accurate monitoring. Beijing has established a multi-level air-quality monitoring network. Figures show 35 standard monitoring stations across the city continuously measure six major pollutants, while more than 1,000 compact sensors deployed across communities and townships provide more detailed information on local air-quality variations.
The monitoring system was gradually built by the Beijing Municipal Ecological and Environmental Monitoring Center, one of China's earliest ecological and environmental monitoring institutions, responsible for monitoring Beijing's air, water, noise, soil environments and ecosystems.
The center has developed an analytical system that can identify around 125 components of PM2.5, covering most of its composition and helping researchers trace pollution sources.
"Source analysis helps us identify the major contributors to pollution at different stages, providing a scientific basis for policymakers to target key emission sources," said Li Yunting, technical director at the center.
Coordinated by the Beijing Municipal Ecology and Environment Bureau, the center has conducted four rounds of PM2.5 source analysis studies with other institutions, with results released in 2014, 2018, 2021 and 2025.
The latest analysis showed that regional transport contributed 57 percent of Beijing's PM2.5 pollution. Among local sources that accounted for the remaining 43 percent, vehicle emissions and residential sources represented the largest share of pollution, a distinctive characteristic of a major international metropolis.
The monitoring results have provided scientific support for a series of pollution-control measures. For example, Beijing has promoted new-energy vehicles to reduce transport emissions and adopted advanced techniques, including air-supported membrane structures, to control dust emissions. Meanwhile, coal combustion pollution, once a major contributor, has almost been eliminated and is no longer listed among the main sources, reflecting broader national efforts to reduce coal consumption, promote clean energy and upgrade heavily polluting industries.
With PM2.5 concentrations now at relatively low levels, further gains in air quality will depend on more targeted, science-driven approaches.
SMARTER ENVIRONMENTAL GOVERNANCE
Beyond monitoring pollution, Beijing has built a data-driven environmental governance system that links monitoring, regulation and enforcement in a closed loop from detection to action and follow-up evaluation.
Developed by the center and known as the innovative regulation-monitoring-inspection linkage model, the system integrates artificial intelligence, the Internet of Things, satellite remote sensing and vehicle-mounted monitoring technologies to pull together environmental data from multiple sources onto a unified platform.
"The system brings information that was once scattered across different departments onto a single platform," said Zhang Likun, director of the smart system division at the center, adding that this enables off-site enforcement and joint cross-sector actions involving housing, water resources and transportation, significantly improving the efficiency and precision of environmental management.
Using more than 30 intelligent algorithms, the platform automatically analyzes data and identifies potential pollution risks, based on which monitoring staff identify the most pressing problems and forward them to enforcement departments.
The approach has already drawn international attention. Clean Air Asia, an international nongovernmental organization focused on improving air quality across Asia, featured the system as a representative case study in its "China Air 2025" report. The model was also presented at the 2026 Better Air Quality Conference and recognized with the Certificate for Clean Air Best Practice Sharing.
China has integrated ecological conservation into its modernization drive. As the country speeds up efforts under the Beautiful China Initiative, Beijing's experience demonstrates how technology can support more precise, coordinated and sustainable environmental governance.

原标题：德广联：德国央行行长放风 欧洲央行加息不足以遏制通胀进一步加息势在必行德广联：德国央行行长放风 欧洲央行加息不足以遏制通胀进一步加息势在必行 中国小康网9月10日讯 老马 欧洲中央银行 (ECB) 启动了其历史上最大规模的加息，以应对持续高企的通胀。欧元区主要利率上升0.75个百分点至1.25%。欧元区的通货膨胀率最近超过了 9%。欧洲央行总部德国广播联盟报道，这是朝着正确方向迈出的重要一步，德国央行行长内格尔 Joachim Nagel 在 Deutschlandfunk 上表示。
。
二 | 他还认为在不久的将来需要进一步加息。作为德国央行行长，内格尔还担任欧洲央行最高决策机构欧洲央行理事会成员。在管理委员会中坐在他旁边的是欧洲央行执行委员会的六名成员和欧元区成员国其他国家中央银行的 18 名行长。
三 | 内格尔表示，欧元区的价格将继续上涨。12月份的通货膨胀率可能会超过百分之十，来年超过百分之六的通货膨胀率显然也太高了。如果通胀情况保持这种状态，利率将不得不上升。理事会必须采取负责任的行动。
四 | 在对抗通货膨胀时，重要的是要发出明确的信号。
五 | 然后，欧洲央行行长克里斯蒂娜·拉加德（Christine Lagarde）只字未提，随后将不得不进一步大幅加息。德国央行行长警告称，通胀不应侵蚀所有领域。低收入尤其受到食品和能源价格上涨的影响。如果通胀固化，也会影响工资。Nagel 预计第三和第四季度的增长率将趋于平稳，新的一年可能会出现衰退。但他说，干旱期不会那么糟糕，很快就会结束。最后，稳定的价格是最重要的。通胀预计也将在 2023 年下降。
