Corporate sustainability is often instantiated within a firm on a continuum, ranging from decoupling behaviors to substantive sustainability actions. Prior research has considered organizational and institutional predictors of this phenomenon, but to date, the role of micro-level mechanisms has been largely overlooked. Yet, individual value orientation and motivation are key indicators of pro-environmental behavior. We consider how values drive a managerÕs end goals, and influence the firmÕs environmental strategy. We also explore how the managerÕs cognitive motivation Ð specifically promotion and prevention regulatory focus Ð moderates these effects. We test our model using quantitative survey with executives in the Mongolian mining industry. While our findings show a significant effect between altruistic value orientation and environmental strategy, there is a lack of direct effects by egoistic and biospheric value orientations. Instead, a managerÕs regulatory focus is a boundary condition that affects how egoistic and biospheric values are expressed in corporate environmental behavior
