Core Viewpoint - The article highlights the successful implementation of a comprehensive registration system for non-road mobile machinery in Shenyang, Liaoning Province, achieving a 78.4% increase in newly registered machines, totaling 3,461 units, thereby enhancing environmental regulation efforts [1][2]. Group 1: Department Collaboration - The management of non-road mobile machinery involves multiple sectors, necessitating a collaborative approach. The Yuhong District Bureau of Ecology and Environment has established a mechanism for inter-departmental cooperation, integrating efforts from construction, transportation, urban management, and local street offices to ensure comprehensive registration management [1]. - The principle of "registration for all machines" is strictly enforced, ensuring that every machine entering a worksite is registered, thus eliminating regulatory blind spots and fostering a unified governance effort [1]. Group 2: Source Guidance - The Yuhong District Bureau has focused on the source of registration by establishing communication channels with 13 non-road machinery sales units and 4 maintenance units, promoting awareness of registration requirements and tracking the flow of machinery [2]. - Through direct engagement with enterprises, the bureau has enhanced the understanding of legal requirements and operational processes related to environmental coding, thereby improving registration efficiency and reinforcing corporate responsibility [2]. Group 3: Smart Application - To address the challenges posed by the mobility and irregular operation times of non-road machinery, the bureau has implemented an environmental regulation APP, facilitating a closed-loop management system for real-time monitoring and registration [2]. - This smart platform allows for efficient tracking and registration of machinery, significantly improving regulatory effectiveness and addressing previous challenges related to locating and registering non-road mobile machinery [2].
