印度已成为全球道路运输部门大气污染物的最大排放国之一。在这里，我们提出了一个最新的清单的废气排放量的十个物种。这份清单是从车辆里程数自下而上计算的，分为七个车辆类别、四个年龄/技术层和三种燃料类型，适用于七个最大的城市以及全国。对流动车队的车龄组成进行了仔细模拟，扣除了仍在登记但实际上已停止使用的车辆的约四分之一。车辆里程根据国家燃料消耗量进行校准，这对于限制不确定性至关重要。敏感性分析揭示了排放因子的主要影响和车辆里程和车辆组成对总排放量的次要影响。对1980年以来的排放量估计进行了审查和鉴定。更全面的检查和维护对于限制污染物排放至关重要;这必须适当地包括商用车辆。它们也是最重要的车辆类别，以解决时，燃料消耗和二氧化碳排放量应控制。(C)2009爱思唯尔有限公司保留所有权利。
India has become one of the biggest emitters of atmospheric pollutants from the road transportation sector globally. Here we present an up-to-date inventory of the exhaust emissions of ten species. This inventory has been calculated bottom-up from the vehicle mileage, differentiating by seven vehicle categories, four age/technology layers and three fuel types each, for the seven biggest cities as well as for the whole nation. The age composition of the rolling fleet has been carefully modelled, deducting about one quarter of vehicles still registered but actually out-of-service. The vehicle mileage is calibrated to the national fuel consumption which is essential to limit uncertainties. Sensitivity analyses reveal the primary impact of the emission factors and the secondary influence of vehicle mileage and stock composition on total emissions. Emission estimates since 1980 are reviewed and qualified. A more comprehensive inspection and maintenance is essential to limit pollutant emissions; this must properly include commercial vehicles. They are also the most important vehicle category to address when fuel consumption and CO2 emissions shall be contained. (C) 2009 Elsevier Ltd. All rights reserved.
