Over recent years, a growing body of empirical evidence highlights a positive correlation between ecological innovation and firm value creation. Building on natural resource‐based view and upper echelons theory, this study examines the relationship between environmental innovation and the cost of debt, by verifying whether and to what extent there is a moderation effect due to the board gender diversity. Using a sample of 458 European firms belonging to the healthcare industry, we carried out a cross‐sectional analysis, given that the sample is based on just the fiscal year 2020. The empirical evidence shows that environmental innovation decreases the cost of debt, by reducing company's perceived risk. In addition, board gender diversity negatively moderates the foregoing relationship. Therefore, our study suggests that public policy makers might underpin environmental innovation policies and specific features on board of directors, since they exert relevant implications on firm's value creation and investors' decisions.
