Investigation of Gas Pollutant Emissions from Fossil ‎Fuel Combustion in Iran from ۲۰۰۰ to ۲۰۱۷‎

Solid fuels such as coal and wood contribute to air pollution by releasing harmful substances into the air during cooking and heating. The burning of coal emits toxins, and industrial activities further degrade air quality. Although natural gas is cleaner compared to coal and oil, it still generates harmful carbon dioxide, with concerns surrounding methane and nitrogen oxides. Tailored policies are essential to decrease emissions in cities like Tehran, Iran, and regions in China, emphasizing the necessity for comprehensive strategies. A search was conducted for keywords related to air pollutants like natural gas, fuel oil, and diesel in online databases such as Google Scholar and Scopus. A review of scientific literature on air pollution caused by these fuels was undertaken, and air pollution production statistics in Iran from ۲۰۰۰ to ۲۰۱۷ were gathered. The One-Sample Kolmogorov-Smirnov Test was used to evaluate the normality of the air pollutant data distribution, and a descriptive study on air pollutant production was carried out using SPSS v۲۷ software, which included statistical tests for correlation analysis. The analysis indicated that from ۲۰۰۰ to ۲۰۱۷, natural gas was the primary producer of CO۲, while diesel was responsible for higher overall pollution despite lower consumption. Significant correlations between pollution levels and fuel types were discovered, with diesel exhibiting the highest emissions, underscoring the necessity for stricter regulations and cleaner fuel alternatives. Strategies to reduce diesel emissions involve increasing natural gas usage, enhancing diesel quality, adopting advanced technologies, promoting electric vehicles, enforcing stringent standards, investing in public transportation.
