Core Viewpoint - Guangdong Province has introduced a special subsidy policy to encourage the replacement of old non-operational heavy-duty trucks, aiming to improve air quality and reduce emissions through financial incentives [1][2]. Group 1: Subsidy Policy Details - The subsidy policy includes two categories: "early retirement subsidy" and "retirement and replacement subsidy" [2]. - The early retirement subsidy applies to non-operational National III and IV heavy-duty trucks registered in Guangdong Province before July 1, 2025, with specific exclusions for certain vehicle types [2]. - Subsidies for medium-duty trucks range from 10,000 to 25,000 yuan, while heavy-duty trucks can receive between 12,000 and 45,000 yuan, reflecting the principle of "more benefits for early retirement" [2][3]. 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].
