The objective of this study is to determine the biogas amount and energy value of biogas pro-duced from livestock manure in Kayseri province and its effects on greenhouse gas emissions (GHG). For this purpose, biogas potential was calculated considering the number of cattle, broil-er chickens and laying hens in the province. According to 2023 data, there are approximately 433.3 thousand cattle, 220 thousand broiler chickens and 3.62 million laying hens in Kayseri province. These livestock in the province produce a total of 4.41 million tons of manure per year, including 4.31 million tons of cattle manure, 440 tons of broiler manure and 105.61 thou-sand tons of laying hen manure. From the usable amount of these manures, 76.4 Mm3 of biogas can be produced annually. The calorific value of the biogas produced from these manures is approximately 1,734.4 TJ and the amount of electricity that can be produced from this biogas is calculated as approximately 192.71 GWhel. This value can supply 4.43% of the annual electricity consumption of Kayseri province (4,344 GWhel). The calculated amount of manure and energy values are mapped by district. When the districts are ranked according to the amount of biogas production, the first three districts are Kocasinan (23.4%), Develi (13.1%) and Pınarbaşı (12.5%). Also, greenhouse gas emission reduction values were calculated to indicate the envi-ronmental benefits of biogas production from farm manure. It was determined that CO2 equiva-lent emission reductions ranging between 902.62 - 1,285.82 thousand tons per year could be achieved by utilizing the calculated biogas potential.
