Government policies on renewing vehicle fleet by introducing newer, cleaner vehicles and removing old, polluting vehicles have significant impacts on air pollution. In this study, the estimated emissions of air pollutants that influence human health are reported together with health endpoints and corresponding mortality and morbidity costs under five alternative road transport policy scenarios, varying in scrapping rate and the shares of hybrid and electric vehicles. Using COPERT software, PM₁₀, PM_2.5, NO₂, and SO₂ emissions are determined for five scenarios. PM_2.5 is the most reduced pollutant (41%) if the government adopts the most progressive scenario, followed by PM₁₀ (27%) and NO₂ (27%). A total of a maximum of 19,396 premature deaths and 803,328 years of life lost could be saved, corresponding to 252 billion TL cost savings over the 2020–2030 period if the most drastic policy encouraging an introduction of the newer and cleaner vehicles is adopted.

政府通过引入更新、更清洁的车辆和淘汰旧的污染车辆来更新车队的政策对空气污染有重大影响。在这项研究中，在五种替代道路运输政策情景下，影响人类健康的空气污染物的估计排放量与健康终点和相应的死亡率和发病率成本一起报告，这些情景在报废率以及混合动力和电动汽车的份额方面各不相同。使用 COPERT 软件，可以确定五种情景的PM ₁₀、PM _2.5、NO ₂和 SO ₂排放量。如果政府采用最先进的方案，PM _2.5是减少最多的污染物 (41%)，其次是 PM ₁₀(27%) 和 NO ₂ (27%)。如果采用最严厉的鼓励引入更新和清洁车辆的政策，最多可以挽救 19,396 人过早死亡和 803,328 年的生命损失，相当于在 2020-2030 年期间节省 2520 亿里拉的成本。
