The textile industry is identified as one of the largest producers of greenhouse gases (GHG) worldwide. It has been reported to generate the highest GHG emission per unit of material. Since, the growing demand for textile products, global textile production has increased rapidly in recent years. Considering the existing studies have limited GHG emissions from energy consumption in the dyeing process. This study aims to estimate GHG emission in the dyeing factory at Samut Prakan province, Thailand, from 2017 to 2019. These were calculated based on the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. The result showed that the textile production in the dyeing factory during 2017, 2018, and 2019 were 2,040.52, 3,389.62, 3,741.68 t. The GHG emission from the production process were 10,541.84 ±1 05.45, 12,320.31 ± 121.65, 12,545.53 ± 121.87 t CO2 eq. The greatest GHG emissions were produced from natural gas utilization (70 % of the total GHG emissions), followed by electricity, fuel oil, gasoline, LPG, and diesel oil. GHG emission flow from the production process found that the supporting processes section was the processes with the largest GHG emissions, accounting for 75 %, followed by finishing, dyeing, and preparation. GHG emissions per production found that GHG emissions per yard reduced from 4.93 ± 1.76, 3.63 ± 0.31, 2.68 ± 0.31 kg CO2 eq/kg of production for 2017 to 2019, because energy type was moved from fuel oil to natural gas.
