This study presents a modelling system to evaluate the impact of weight reduction in light commercial vehicles with diesel engines on air quality and greenhouse gas emissions.The PROPS model assesses the emissions of one vehicle in the aforementioned category and its corresponding reduced-weight version. The results serve as an input to the RIAT + tool, an air quality integrated assessment modelling system.This paper applies the tools in a case study in the Lombardy region (Italy) and discusses the input data pre-processing, the PROPS-RIAT + modelling system runs, and the results.

轻型商用车重量减少对燃料消耗，CO ₂排放，空气质量和社会经济成本的影响

这项研究提出了一个建模系统，以评估轻型柴油发动机商用车的减重对空气质量和温室气体排放的影响.PROPS模型评估上述类别及其对应的减重版本中的一辆汽车的排放量。结果将作为空气质量综合评估建模系统RIAT +工具的输入。本文将这些工具应用于伦巴第地区（意大利）的案例研究中，并讨论了输入数据预处理PROPS-RIAT +建模系统运行以及结果。
