Although prior studies draw upon natural resource-based views, environmental strategy permits competitive advantages, and as such, gains financial performance. However, empirical results are mixed. To shed light on this issue, this study proposes that environmental performance mediates the link between environmental strategy and financial performance. Data were collected from 175 third-party logistic providers currently operating in Vietnam to test the hypotheses. Partial least square structural equation modeling was borrowed to test the data. The results reveal environmental performance partially mediates the link between environmental strategy and financial performance. By considering the mediating effect, this study contributes to the literature by addressing the intervening mechanism of environmental performance on the inconclusive relationship between environmental strategy and financial performance. Besides, this study also extends prior studies by borrowing a concept of environmental strategy, which captures the extent of organizations pursuing this strategy, to explain how and why pursuing this strategy permits environmental and financial performance.
