This study aims to increase competitive advantage of Thai Arabica coffee by improving its value chain performance towards sustainability perspective including economic, social, and environmental aspects. Data were collected from key players along the supply chain by face-to-face interviewing using a semi-structured interview form. Results of this study show that in the social aspect, information and material flow along the chain are satisfactorily effective, while relationship between key players especially in downstream part is relatively weak. In addition, the interview results show that the Arabica coffee promotion efforts done by the manufacturers has created positive impacts on communities. In the economic aspect, it is found that the added value gained by the franchisees is the largest at 88%, while that of the coffee growers’ ranges from only 2.2% in the franchising channel to 17.4% in the export channel, with the average added value at 8.5%. In the environmental aspect which is assessed by the product’s carbon footprint released during coffee growing, processing, and distributing stages as the direct emissions from the use of fertilizer, electricity, and fossil fuels, calculation results show that the coffee grower activities including cultivation and coffee cherries transport have the largest Global Warming Potential (GWP) contribution, with the calculated total GWP value of 1 kg of roasted coffee bean being 3.3 kg CO2e. Findings from this study reveal that there still are potentials to improve sustainability performance of this Thai Arabica coffee value chain.
