Applying Social Life Cycle Assessment in the Thai Sugar Industry: Challenges from the field

Abstract

This paper discusses the challenges in applying Social Life Cycle Assessment (S-LCA) in the Thai sugar industry sector. A case study of an S-LCA of sugar in Nakhon Ratchasima province was undertaken following the UNEP/SETAC guidelines for S-LCA of products. Qualitative evaluation was made to assess an extent to which S-LCA is applicable for the Thai sugar industry sector. Based on the results from this study, the main challenges in applying S-LCA in the Thai sugar industry sector are diversity of scope of study and reference flow choices, difficulty in data collection and data quality, limited choices of social subcategories and indicators to assess social impact at product level for some stakeholder groups and absence of established interpretation approach. Though findings are derived for the sugar industry, many of them could also be applied to other systems. The main social issues that need urgent attention are problems such as cane trash burning that affects local health and safety, low wages, land and water rights. Appropriate ways to conduct S-LCA for Thai sugar industry have been suggested. In addition, it was suggested that the S-LCA of Thai sugar industry should be conducted at provincial level scope.
