Research on Promotion Pathways for Zero-Emission Medium- and Heavy-Duty Trucks: A Case Study of Hainan Island

Promoting the use of zero-emission vehicles is an important measure for reducing pollutant and carbon dioxide emissions from medium- heavy-duty trucks (MHDTs). This study took Hainan Island as example. Based on big data such industrial layout traffic flow, it clarified that main channels freight transportation are concentrated in northern region, including surrounding areas Haikou; ports Haikou, Yangpu, Basuo; Chengmai Tunchang counties. Furthermore, pathways promotion MHDTs proposed, which can reduce exhaust by 1549 tons NOx, 62 particulate matter (PM), 3.60 million CO2 2030. Compared with vehicle type categorization plan, spatial plan achieve higher emission reduction benefits medium term (2025). In addition, conjunction existing policies planning requirements, this also puts forward policy suggestions MHDTs.
