RT Journal Article T1 How Environmental Assurances and Certifications Shape Environmental Scores and Their Relationship with Environmental Controversies: Evidence from the Main European Union Companies A1 González Sánchez, Francisco José A1 Moreno Adalid, Ana María A1 Rubio Martín, Gracia María A1 Cid Moreno, Daniel AB This study examines whether environmental assurance and environmental managementcertifications are associated with subsequent environmental performance and reputationalexposure in European Union listed firms. Using Refinitiv Eikon panel data for 441 firms(1773 firm-year observations) from 2017–2023, we analyze environmental pillar sub-scores(Emissions, Resource Use, and Innovation) and three intensity indicators (energy, pollution,and recycled waste intensity). We estimate firm fixed-effects models for performanceoutcomes and Firth’s logistic regression models for media-reported environmental controversies,using lagged assurance/certification indicators. Environmental assurance isconsistently associated with higher environmental sub-scores and with lower energy andpollution intensity, alongside higher recycled waste intensity. In contrast, certificationeffects are weaker and more heterogeneous across intensity-based indicators. Regardingreputational exposure, assured firms show a higher likelihood of subsequent media-reportedenvironmental controversies, which is consistent with heightened scrutiny andvisibility rather than evidence of intent. These findings inform boards, assurance providers,investors, and policymakers seeking to strengthen the credibility and use of corporateenvironmental information.
