Journal on Management 2230 – 715X 10 4 26 36 CorpSustainability Reporting, Stakeholder Management, Transparency Due to sector importance, size and strong growth rates, Aerospace and Defense (A & D) companies need to engage appropriately with stakeholders and communicate effectively their corporate policies, strategies and actions. As a result, in recent years, they have faced greater scrutiny and calls to produce sustainability reports. They rely on internationally recognized frameworks to create such reports. The Global Reporting Initiative (GRI) is one of the most trusted guidelines, being the nearest thing that exists to a standard for responsible management reporting. However, it is unclear whether it effectively fulfills its mission. The present paper explores the disclosure and information content of the top revenue-generating companies in the A&D industry. Results show that, there is a need for further development of the GRI guidelines in a sector-specific fashion, together with higher detail and specification in firms' disclosure of information, to achieve overall greater transparency.
