The paper aims to depict the forces responsible for an effective introduction of a sustainability report within SMEs. The paper’s aim is addressed employing the case study methodology. In detail an SME considered a best practice in introducing sustainability innovations has been selected and analyzed. The main outcome of the paper is to use the case study evidence to construct a conceptual model highlighting the forces that drive companies to introduce innovative sustainable management tools. The conceptual model emphasizes as driving forces the capability of the firm to engage with its stakeholders, together with some relevant managerial and organizational features.
