This research studies the quantity of greenhouse gases emission emitted by the power plant's electricity generation. Employing carbon footprint evaluation, the research studies from the acquisition and transportation of raw materials to the electricity generation in order to evaluate the quantity of carbon footprints and their reduction. Carbon footprint from the generation of electric power plants in Thailand using fossil fuel, 4 cases, such as power generation of Bangprakong combined cycle power plant no. 1-2 with natural gas and diesel fuel. Bangprakong combined cycle power plant no. 3-4 using natural gas. Krabi thermal power plants using fuel oil and diesel fuel and Maehongsorn diesel power plant. The study also introduces some basic guidelines for reducing carbon footprint. To evaluate carbon footprint is to use software package SimaPro 7.2.4 is used and its boundary is Business-to-business (B2B) type. The results of it are carbon footprint in every case,mostly time over 20 years, secondly 100 years and the least time over 500 years. Maehongsorn diesel power plant cause the highest carbon footprints 1.06 0.977 and 0.947 kg CO₂ eq/kWh, respectively, followed by Krabi thermal power plants using fuel oil as the main causing the carbon footprint 0.966 0.918 and 0.898 kg CO₂ eq/kWh, respectively. Bangprakong combined cycle power plant using natural gas as primary fuel to generate has the smallest carbon footprint, 0.89 0.744 and 0.689 kg CO₂ eq/kWh respectively. The carbon footprint caused by the generation process of electricity most, followed by the process of acquisition of raw materials.The process of shipping raw materials will cause the least carbon footprint.The introductory options for carbonfootprint mitigation are using wind, solar and nuclear energy for power generation combine case study and using CCS
