Do Environmental Certifications Pay? A Bibliometric and Systematic Review of Environmental Management Systems and Eco‐Label Impacts

This paper investigates how environmental certifications—specifically, formal environmental management systems (EMSs) (ISO 14001, EMAS), and consumer-facing eco-labels—influence firm financial performance. Using a dual approach that includes a bibliometric review and a systematic analysis of key studies, we identify key trends, theoretical underpinnings, and methodological approaches across these distinct certification types. Our bibliometric results highlight a rapidly evolving field, with EMSs and eco-label research growing along different paths and showing varying levels of international collaboration. The systematic review complements these findings by examining evidence on how certifications impact internal efficiencies, market positioning, and overall profitability. We observe that benefits depend strongly on organizational context, implementation quality, and stakeholder engagement. By integrating insights from both reviews, this paper clarifies the conditions under which environmental certifications enhance financial outcomes and offers directions for future research aimed at advancing both environmental responsibility and firm-level success.
