Translating Corporate Sustainability Policies into Employee Pro-Environmental Behaviors: Evidence from Thai Organizations

In Thailand, companies are facing increasing pressure from investors, consumers, customers, and regulators to integrate sustainability into business policies and practices. Achieving corporate sustainable development requires incorporating environmental attitudes and work environments into employee behaviors. This study examines how perceived sustainability policies (PSP) influence pro-environmental behaviors (PEB) in the workplace. A total of 589 respondents from four Thai companies in diverse sectors—rubber, consumer products, B2B industrials, and garments—participated in the study. Grounded in the Focus Theory of Normative Conduct, the research extends individual-level psychological frameworks by incorporating the mediating roles of organizational-level descriptive norms—green shared vision (GSV) and green work climate (GWC)—and the moderating role of individual green value (IGV). Structural equation modeling was conducted using AMOS. The findings supported both a direct effect of PSP on PEB and a sequential mediation pathway through GSV and GWC, while the individual mediation roles of GSV and GWC were not significant. These results reflected strong institutional and in-group collectivist culture of Thailand. Moreover, IGV was found to have a significantly negative moderating effect, suggesting that employees with high IGV may rely less on formal perceived sustainability policies in shaping their pro-environmental behaviors.
