Diesel's Share of Pollutants and Greenhouse Gas Emissions among All Energy Sources in Iran from ۲۰۰۰ to ۲۰۱۷

The annual pattern of diesel pollutant emissions is a significant environmental concern, with key pollutants such as suspended particulate matter, nitrous oxide, sulfur trioxide, sulfur dioxide, and nitrogen oxides impacting human health and the environment. A literature review focused on diesel-emitted pollutants was conducted using online databases. Data on diesel-related air pollution in Iran were collected, examining emissions of various pollutants from ۲۰۰۰ to ۲۰۱۷. Data distribution was analyzed using the Kolmogorov-Smirnov test. Descriptive and correlation analyses were performed using SPSS v۲۷ to explore relationships among greenhouse gases and air pollutant emissions. The study examines the impact of diesel on pollutants and greenhouse gas emissions in Iran from ۲۰۰۰ to ۲۰۱۷. It shows a small decline in diesel's share of NOx emissions, attributed to better combustion efficiency and emission control systems. In contrast, diesel's share of SO۲ emissions has risen, likely due to increased diesel use despite a shift to natural gas and renewable energy. CO emissions have remained stable due to improved technologies, and CH۴ emissions have significantly dropped due to reduced methane slip and bio-based diesel adoption. The study also indicates a decrease in diesel's contribution to SPM, linked to better fuels and particulate filters. The correlation analysis reveals significant inverse relationships between CO۲ and N۲O emissions and suggests that reducing one type of pollution may affect another.
