Essays on sustainability: the impact on firms' performance and innovation

Eco-innovation is crucial for companies to balance environmental compliance with profitability. It involves implementing more efficient resource use and reducing harmful environmental effects. However, eco-innovation requires significant resources and corporate commitment. This thesis examines how sustainability affects firms’ performance and how some firms’ structures influence this relationship. Three articles are included: one studies the moderating role of the supply chain network in the relationship between corporate environmental and financial performance; the second studies how board gender diversity impacts eco-innovation through a moderated mediation model introducing the CSR committee as a mediator and board-independent members as a moderator; and the third studies the link between eco-innovation and productivity in reducing GHG emissions.
