Wuhan Economic & Technological Development Zone (WEDZ) is making significant strides in sustainable development, as highlighted in a recent air quality report, revealing that the zone achieved 284 days of excellent air quality in 2025.
This achievement could be attributed to measures implemented by authorities, including the development of low-carbon industrial parks, the adoption of digital governance, and the addressing of river pollution.
These initiatives have led to notable accomplishments in green and low-carbon development, earning WEDZ recognition as the home of 17 national-level green factories, two national-level green supply chain management enterprises, and 35 waste-free factories.
For example, Geely Auto Wuhan branch's painting workshop utilizes ABB robots for precision spraying, achieving a high paint recovery rate of 98 percent and reducing VOC (volatile organic compounds) emissions.
The company's welding workshop employs 50 percent aluminum materials and 16 connection techniques, reducing vehicle body weight and minimizing welding fume emissions to industry lows.
This facility is the first in the world to apply digital twin technology across all processes, with rooftop and parking canopy solar panels generating over 23,000 megawatt-hours annually, reducing carbon emissions by nearly 13,000 metric tons per year.
WEDZ has deployed a comprehensive intelligent sensing network that includes drone monitoring, lidar mobile detection, online monitoring, and electricity usage surveillance. This network conducts 110 drone monitoring missions and over 500 lidar mobile detections annually, with 200 electricity-monitoring systems installed at key enterprises to track real-time operations of pollution-control and production facilities.
A ship pollutant terminal has also been established along the Yangtze River, offering free reception of domestic sewage, garbage, and oily wastewater from passing ships. The terminal has annually processed 61,000 tons of domestic sewage, 2,028 tons of ship garbage, and 57,000 tons of oily wastewater since its launch in 2023.
