(Xinhua/Sun Suying)Beijing's blue skies have become a visible sign of the city's progress in tackling air pollution, and behind that progress, digital technologies are playing an increasingly important role.
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.
。图为昨天早上市民在柳浪闻莺微笑亭购买“爱心莲莲”套餐。" />昨天早上8点半，西湖荷叶莲蓬爱心义卖活动在柳浪闻莺微笑亭如约开摊。

二 | 现场，音乐剧《钱氏今生》里的钱王和吴夫人的扮演者黄千懿、董静也到场助阵，为市民送上祝福。图为昨天早上市民在柳浪闻莺微笑亭购买“爱心莲莲”套餐。每到盛夏，许多老杭州人就会有一种莫名的期待——西湖的荷叶与莲蓬，昨天，大家心心念念一整年的“西湖有爱·好运莲莲”爱心义卖热闹开集，地址还设在老地方：柳浪闻莺微笑亭。早上8点20分，记者赶到现场时，已经有不少市民提前排队等候。年近90岁的洪先生早上6点左右抵达西湖边，拿到了第5号。“特别高兴。

三 | ”老人笑呵呵地举着号码牌说。在这位老杭州人的心中，西湖的山水是童年一份特殊的印记，“我们小时候到湖里抓鱼、摸虾，退休了之后没事儿就过来转转，对这里特别有感情。

四 | ”洪先生说，自打西湖莲蓬义卖的第一年以来，自己就参与了，此后年年到场，“尝过之后就会知道，西湖长出的莲子和莲蓬味道和其他地方的不一样，荷叶还可以用来泡茶，香气扑鼻。”昨天的1号小票，被准高三学生操睿收入囊中，小姑娘骑了1小时的车，凌晨4点多到达现场，“去年我也来了，今年比预想中的人少一点，没想到真的拿到1号，希望能借着好运给接下来的高三生活开一个好头。”早上8点30分，义卖活动准时开启，市民们按照号码牌有序排队，“爱心莲莲”套餐还是老规矩：10元钱能够买到3个莲蓬和5张荷叶，每人限购一份，售完即止。

五 | 领到爱心套餐的市民都迫不及待地打开袋子，满眼欣喜地展示“战利品”：有人第一时间拍照分享，有人直接剥开莲蓬品尝果实的清甜，还有小朋友顽皮地举起荷叶，当成帽子……每个人的脸上都洋溢着由衷的快乐。西湖景区水域管理处水生植物养护班班长俞阳洋说，这些带着“鲜气儿”的爱心套餐都是西湖养荷人凌晨4点采摘下来的，“为了确保荷花健康和美态，养荷人会一根根疏理，然后将这些带着露水与清香第一时间送到微笑亭。”俞阳洋透露，荷花喜欢阳光，由于台风刚过以及近期阴雨影响，部分荷叶叶面上可能有斑点等，样子没那么完美。同时西湖荷花属于观赏性“花莲”，莲蓬产量等都比不了专供食用的“子莲”。所以每天义卖数量将根据天气和荷花生长情况而定，还请大家理解。

六 | 今年的爱心义卖从昨天开始将持续至8月下旬。其间，每周一到周五上午7时，在柳浪闻莺微笑亭发放当日号码牌；8点30分至9点凭号码牌当场购买，过时号码作废；请自备零钱，或使用支付宝支付。

七 | 如遇雨天或双休日，义卖活动暂停，所有的义卖善款将全部捐给慈善机构。需要再次提醒市民朋友，天气炎热，请大家注意防暑，根据自身状况前往，文明有序购买。
