Sustainability of a business may be expressed as the capacity of an organisation to continue its operations over a long period of time and depends to a large extent on stakeholder relationships. Sustainability reporting is being used as a communication tool to highlight organisation commitment towards sustainability and enhance relationships with stakeholders. With some stakeholder groups being in a position to influence the quality of sustainability disclosures, the objective of this paper is to find if the quality of disclosures in sustainability reports is influenced by pressure from key stakeholders groups like customers, investors, employees and NGOs or environmental organisations. To achieve the objectives a dimension of quality of sustainability disclosures is extracted using Principal Component analysis (PCA) technique of factor analysis. Industrial sector, listing status and size of the organisation are used as proxy for stakeholder salience. Using step wise multiple linear regression, the study finds causal relationship between quality of disclosures and stakeholder salience. The results show that organisations operating in environmentally sensitive sector, consumer contiguous sector, financial sector, in areas where sustainability reporting is regulated, large size and listed organisations and provide high quality disclosures.
