Hangzhou split the city into 48,000 sensor grid cells and put AI pollution detectors on buses and taxis — the bureau says it now flags dust hotspots in real time, though the accuracy numbers are entirely self-reported.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

The Hangzhou Ecology and Environment Bureau's 'Eco-Smart Guard' (生态智卫) platform divides the city into roughly 48,000 micro-grid cells of 300m x 300m and fuses fixed monitors with mobile sensors mounted on electric buses and taxis, processing over 500,000 data points an hour with an AI model to flag construction-dust and other particulate hotspots in near real time. Reported in Hangzhou government coverage in 2024-25, the system flagged over 4,000 high-dust incidents with a claimed 95% early-warning accuracy and an 80% success rate tracing pollution back to a source; the bureau credits it as one factor behind a 6.7% year-on-year drop in average PM10 to 47.1 micrograms per cubic metre in 2024. All figures are self-reported by the operating bureau; no independent audit of the accuracy or attribution claims was found.
📊 Impact
48,000 micro-grid cells (300m x 300m each); over 500,000 data points processed per hour; 4,000+ high-dust incidents flagged; 95% early-warning accuracy and 80% source-tracing success claimed by the bureau; city-average PM10 fell 6.7% year-on-year to 47.1 µg/m3 in 2024.
🎓 Lesson
The bureau credits the AI system for a real, city-measured pollution drop — but every number in that chain, including the accuracy rate of the AI itself, comes from the same self-reporting bureau, with no outside audit found.
