The carbon footprint was assessed through data modeling based on the International Panel on Climate Change (IPCC) method. The functional unit was defined as one kilowatt-hour (kWh) of electricity generated, and the system boundary was set as gate-to-gate.</span></span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="line-height:107%"><span calibri="" style="font-family:"><b><span style="line-height:107%"><span new="" roman="" style="font-family:" times="">Results:</span></span></b> <span lang="EN" style="line-height:107%"><span new="" roman="" style="font-family:" times="">The study revealed that the most significant environmental impacts of the power plant were related to human carcinogenic toxicity, accounting for 42% at the midpoint level, and damage to human health, contributing 86% at the endpoint level. Sensitivity analysis identified natural gas as the most influential factor affecting the results. According to the IPCC method, fossil fuel consumption contributed 94% to the global warming potential. The highest amount of CO₂ emitted was 0.946 kg per kWh of electricity produced.</span></span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:107%"><span calibri="" style="font-family:"><b><span style="line-height:107%"><span new="" roman="" style="font-family:" times="">Conclusion:</span></span></b> <span style="line-height:107%"><span new="" roman="" style="font-family:" times="">The CO₂ emissions per kWh of electricity produced (0.946 kg/kWh) exceeded the average CO₂ emission factor for fossil fuel power plants in Iran (0.64 kg/kWh). Based on these findings, it is recommended to prioritize the use of renewable and clean energy sources, such as wind and solar power, as alternatives for electricity generation in the region.</span></span></span></span></span><br> &nbsp;</div> ردپای کربن, ارزیابی چرخه حیات, سوخت فسیلی, نیروگاه حرارتی Carbon footprint, Life cycle assessment, Fossil fuel, Thermal power plant 155 170 http://ijhe.tums.ac.ir/browse.php?a_code=A-10-1188-2&slc_lang=fa&sid=1 Mohadeseh Narouei محدثه نارویی mohim9203@gmail.com No Department of Environmental Science, Faculty of Natural Resources, University of Zabol, Zabol, Iran گروه محیط زیست، دانشکده منابع طبیعی، دانشگاه زابل، زابل، ایران Narjes Okati نرجس اکاتی narjesokati@uoz.ac.ir Yes Department of Environmental Science, Faculty of Natural Resources, University of Zabol, Zabol, Iran گروه محیط زیست، دانشکده منابع طبیعی، دانشگاه زابل، زابل، ایران Fatemeh Einollahi Peer فاطمه عین الهی پیر fatemeheynollahi@uoz.ac.ir No Department of Environmental Science, Faculty of Natural Resources, University of Zabol, Zabol, Iran گروه محیط زیست، دانشکده منابع طبیعی، دانشگاه زابل، زابل، ایران
