Developing an official program to calculate heavy-duty vehicles CO₂ emissions in Korea

In 2020, Korean government introduced a CO₂ monitoring regulation that heavy-duty vehicle (HDV) manufactures are required to submit CO₂ calculation data using Heavy-duty vehicle Emission Simulator (HES). Based on HES program, the mandatory CO₂ regulation for HDVs is expected to be implemented from 2026. This study addresses the development of HES program, which is a vehicle dynamics-based vehicle system model that estimates fuel consumption and CO₂ emissions of HDVs. The CO₂ prediction accuracy of HES was rigorously validated with 19 experimental data, and the average CO₂ emission error between the experimental values and HES results was 4.6%. For comparative analysis between HES and European HDV simulation program VECTO, 21 simulations were performed using the same input data for both programs, and the average CO₂ emission error is 1.59%. Using the HES program, the authors calculated CO₂ emissions from HDVs from 2015 to 2020 in Korea.
