PurposeThe purpose of this paper is twofold: first, it aims at the identification and assessment of the commitments towards sustainable development (SD) communicated to all interested parties (stakeholders) by top management; and second, mapping the profile of the organisations which prominently communicate those commitments.Design/methodology/approachThe research methodology was supported on the content analysis of the organisations’ statements (disclosed on the institutional website) that sustain the strategy and policies (organisational culture). A total of 540 certified Portuguese organisations in Quality, Environment and Occupational Health and Safety (QEOHS) comprised the sample.FindingsAccording to this research, it is possible to identify three main commitments towards SD addressing customers (consumers), human resources (employees) and continuous improvement. Furthermore, results suggest that commitments towards customers and human resources fit properly into the theoretical assumptions of the stakeholder theory and, in turn, the commitment towards continuous improvement fits accurately into the assumptions of the “normative isomorphism” of the institutional theory. Moreover, the results pointed out the characteristics of Portuguese organisations (QEOHS) that prominently communicate commitments towards SD: large business volume, located in Lisbon or Setubal, fall within the public business sector, are members of the BCSD Portugal and publish annual reports on the institutional website.Research limitations/implicationsSolely organisations operating in Portugal and simultaneously encompassing three certified management subsystems (against the clauses of ISO 9001, ISO 14001 and OHSAS 18001 standards) were considered throughout this study. So it is not possible to ascertain at which extent the conclusions are valid. However, although the statistical generalisation of the results may be precluded, there is not any peculiar reason preventing the analytical generalisation, namely, in organisations operating in countries with similar macro-characteristics of Portugal.Originality/valueTo the best of authors’ knowledge this is the first time that such a comprehensive, detailed and thorough analysis of the communicated commitments towards SD is carried out regardless the activity sector. The conclusions from this paper are useful both for practitioners and scholars. On one hand companies have now information on the more often communicated statements, while on the other hand academics and scholars will benefit from this research and hopefully be able to replicate it in other contexts.
