Core Viewpoint - The recent measures taken by the Ministry of Ecology and Environment aim to enhance the regulation of vehicle emissions in response to the severe pollution caused by motor vehicles, particularly heavy-duty vehicles, which are significant contributors to nitrogen oxide emissions [2][3][4]. Group 1: Current Situation of Vehicle Emissions - The total number of motor vehicles in the country has exceeded 450 million, with nitrogen oxide emissions reaching 4.7 million tons annually, accounting for over one-third of the national total [3]. - Heavy-duty fuel vehicles, despite representing only 2% of the total vehicle count, contribute 75% of nitrogen oxide emissions, amounting to 3.5 million tons [3]. - A significant number of heavy-duty vehicles have been found to engage in fraudulent practices, with 39% of inspected vehicles exhibiting tampering with pollution control devices [3][4]. Group 2: Issues with Inspection Agencies - Among 1,823 inspected vehicle inspection agencies, 46% were found to have serious issues, including issuing false compliance reports and using cheating devices [4]. - In a sample of 83 maintenance stations, 41% were found to issue false maintenance certificates, further complicating the regulatory landscape [4]. Group 3: Causes of Frequent Issues - Low utilization rates of remote sensing monitoring equipment, with only 50% operational, hinder effective emissions monitoring [6]. - Ambiguities in regulatory responsibilities among various departments contribute to the prevalence of fraudulent activities [6]. - The emergence of new cheating methods, such as the use of devices that can manipulate inspection results, has been reported across multiple provinces [7]. Group 4: Regulatory Improvements - The Ministry of Ecology and Environment has initiated multiple rounds of special supervision and inspections to combat fraudulent practices in vehicle emissions testing [9]. - Plans are underway to establish a long-term regulatory mechanism, including stricter oversight of inspection agencies and enhanced responsibilities for ecological departments [9][10]. - The integration of big data and AI technologies is being pursued to improve the efficiency of emissions regulation and identify anomalies in vehicle emissions [10][11].
