Abstract

The purposes of this research are to investigate the social and environmental reporting based on the GRI reporting framework, version 3.1 among firms in the SET 100 index group (100 firms). Based on the GRI reporting guidelines, the checklist, which consisted of 5 aspects and 48 core indicators, was developed as a research instrument to measure the extent of social and environmental reporting. In addition, the content analysis was applied to review and to extract subjects of social and environmental reporting from their annual reports, their annual registration statements, their offering securities statements and their sustainability reports for the year ended 2014. The content analysis was applied to codifying the text of the social and environmental reporting for calculating the social and environmental reporting index. Then, collected data were analyzed by the descriptive statistics.


          Research findings showed that the extent of social and environmental reporting among firms in the SET 100 index group was relative low, average not more than 10% and they reported some items in each aspect. The industrial groups (petrochemicals and chemicals sector) and the resource group (energy and utilities sector) had higher level of social and environmental reporting than other industry groups. On the other hand, the service group had the lowest level of reporting. In respect of 5 aspects of GRI reporting, all industry groups had more reported in the social aspect than other aspects.


          Research findings of this study were consistent with stakeholder theory in that Thai firms might get low pressure from stakeholders; therefore, they had low level of reporting based on GRI.  In addition, the industry group may be a factor affecting the social and environmental reporting of Thai firms.  Under legitimacy theory, the industries operating with high risk to social and environmental effect would get high pressure from external stakeholders to disclose social and environmental information.
