The dilemma of firms in developing economies was the crux of this study. In probing whether the adoption of organization-wide green strategy would enhance the product quality and the firm’s financial lifeline, while also improving the environment, we developed a mediation model. The specific objectives were to ascertain the direct effect of green strategy on both environmental and financial performance and its total effect on both environmental and financial performance through product quality. With data collated and analyzed from 648 respondents, using the Hayes mediation approach, results show that while environmental performance is strongly predicted by green strategy and product quality (as a mediator), financial performance is also positively predicted, but by a smaller effect. The import of the findings of this study is that the adoption of green strategy mediated by product quality improves both environmental and financial performance, implying that firms can remain financially viable while adopting product-focused green strategy.
