Core Viewpoint - The article highlights the illegal modification of heavy-duty trucks in China, specifically the installation of a screw on the exhaust temperature sensor, which significantly increases harmful emissions by preventing the proper functioning of the urea injection system [1][3][4]. Group 1: Illegal Modifications and Their Impact - A small screw can turn a heavy-duty truck into a mobile source of pollution, with emissions potentially increasing by dozens of times [1][3]. - In a recent inspection in Zhengzhou, only one out of fifty trucks was found to have this illegal modification, indicating a decrease in such practices due to increased enforcement [1][3]. - Heavy-duty trucks account for 80% of nitrogen oxide emissions from vehicles, making them a primary target for pollution control efforts [4]. Group 2: Economic Incentives for Illegal Modifications - Truck drivers are motivated to modify their vehicles to save costs, as the annual expense for urea can reach around 10,000 yuan, while modifications can lead to savings of several thousand yuan [5][4]. - The availability of "urea-saving screws" on e-commerce platforms, often sold with installation tutorials, facilitates these illegal modifications [5][10]. Group 3: Regulatory and Enforcement Measures - The Chinese government has recognized the need for a coordinated approach to combat illegal modifications, involving multiple departments such as ecology, transportation, and market regulation [11][10]. - Recent policies emphasize the importance of regular inspections and the establishment of a blacklist for repeat offenders [11][10]. - E-commerce platforms are urged to take responsibility for monitoring and removing illegal products that facilitate these modifications [10][11].

Group 1 - The core point of the report indicates that mobile source pollution has become a significant contributor to air pollution in China, with total emissions reaching 18.582 million tons in 2024 [1] - Among mobile sources, motor vehicles accounted for 12.856 million tons of pollutants, with cars being the primary contributors, responsible for over 90% of emissions of carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter [1] - Diesel vehicles are particularly concerning, with nitrogen oxides and particulate matter emissions constituting 87.1% and over 99% of total car emissions, respectively [1] Group 2 - Non-road mobile sources, including construction machinery, agricultural machinery, ships, and railway diesel locomotives, contributed 5.726 million tons of emissions in 2024 [2] - The transportation structure in China is predominantly road-based, handling approximately 70% of passenger and freight transport, highlighting the need for optimization towards electrified railways and clean shipping [2] - The Ministry of Ecology and Environment plans to enhance efforts in pollution management, focusing on diesel truck pollution control and improving mobile source environmental management to effectively reduce emissions and improve air quality [2]

Group 2: Additional Incentives - In addition to the retirement subsidy, owners can receive a replacement subsidy if they purchase new energy heavy-duty trucks (pure electric or hydrogen fuel cell vehicles) between July 1, 2025, and December 31, 2026 [3]. - The replacement subsidy amounts to 35,000 yuan for medium-duty new energy trucks, while heavy-duty trucks receive subsidies based on axle count: 70,000 yuan for 2 axles, 85,000 yuan for 3 axles, and 95,000 yuan for 4 or more axles, allowing for a maximum total subsidy of 140,000 yuan per vehicle [3]. - This policy aims to fill the gap in existing national policies that primarily cover operational vehicles and specific passenger cars, thus providing comprehensive incentives for the retirement of high-emission old trucks [3]. Group 3: Environmental Impact - The initiative is part of a broader effort to address mobile source pollution, as heavy-duty fuel trucks, which constitute less than 2% of the vehicle ownership in Guangdong, account for 58% of nitrogen oxide emissions from vehicles [3].
