Core Viewpoint - The Ministry of Ecology and Environment emphasizes the importance of heavy-duty trucks in pollution control, as they account for 75% of nitrogen oxide emissions despite being only 3% of the vehicle fleet. The focus for the "14th Five-Year Plan" is on enhancing standards, structural adjustments, targeting major users, and strengthening regulatory enforcement [1][2][3]. Group 1: Standards and Upgrades - The implementation of national standards such as the National VI for vehicles and National IV for non-road mobile machinery is crucial for upgrading emission control levels and aligning with global standards [1]. - By 2025, the national automobile export volume is expected to exceed 7 million units, contributing significantly to environmental technology upgrades [1]. Group 2: Structural Adjustments - The shift towards rail and water transport for coal and other resources has led to a 13.7% increase in railway freight and a 28.8% increase in waterway freight over the past five years [1]. - The proportion of heavy-duty trucks meeting National V and above standards has risen from 48% to 85%, with the number of new energy vehicles reaching 43.97 million, accounting for 12% of the total vehicle fleet [1]. Group 3: Major Users and Clean Transport - Heavy-duty trucks in key industries such as coal, steel, and electricity account for about two-thirds of the total, with a projected sales volume of 198,000 new energy heavy-duty trucks by 2025 [2]. - The clean transport ratio in key industries is expected to approach 80%, with over 9,000 enterprises connected to a national platform for monitoring [2]. Group 4: Regulatory Enforcement - The upgrade of the mobile source technical defense system is underway, with over 15,000 emission inspection institutions connected to a national platform [2]. - A special rectification of vehicle emission inspection institutions has been initiated, resulting in a 40%-60% decrease in fraudulent practices among heavy-duty trucks [2]. Group 5: Future Plans - The "15th Five-Year Plan" aims for comprehensive efforts in mobile source management, focusing on stringent regulations for diesel trucks and non-road machinery, and promoting zero-emission logistics [3]. - The Ministry plans to accelerate the development of new standards for vehicles and machinery to support pollution reduction and carbon neutrality [3].
