Introduction: Air quality management and pollution control from mobile and stationary sources are of paramount importance from both environmental and human health perspectives. One key aspect in this regard is estimating air pollution emissions from vehicles and other mobile sources. Due to the diverse performance of vehicles under different conditions, estimating these emissions poses significant challenges for researchers and industry professionals alike. Hence, the use of accurate and reliable tools for such estimations is essential. The International Vehicle Emissions (IVE) modeling software is one of the main tools used in the development of emission inventories for air pollution studies in many countries. Material and Methods: This study compared IVE model data and measured emissions from zero-kilometer internal combustion engine passenger vehicles to examine the deviation of model values from reality. These measurements were performed using a chassis dynamometer test at ISQI laboratory, following the Euro 4 emission standard and the New European Driving Cycle (NEDC). Results and Discussion: The comparison of emission data obtained from the chassis dynamometer test of internal combustion engine vehicles with those modeled by IVE revealed differences in emission levels, particularly notable for nitrogen oxides (NOx). These disparities indicate that the IVE model may not accurately represent reality and requires necessary adjustments. Conclusion: Managers and decision-makers in air quality and environmental management should carefully consider the results of research and experiments in this field. Analysis of emission levels indicates that the IVE model, in some cases, may not closely reflect reality and relying on hypothetical conditions for estimating pollutant levels is unreliable. Improvements to the IVE model are necessary to enhance the accuracy of these estimations, contributing to better assessment quality and improved performance in air quality and environmental management. Developing data-driven and transparent approaches and solutions holds significant importance in this regard and can lead to considerable improvements in air quality management and pollution reduction efforts.
