This paper reports on the findings of an on-going research study, which is focused on managing change and knowledge associated with sustainability initiatives for organisational competitiveness.

It involved semi-structured interviews with twenty six professionals from seventeen UK organisations in four sectors - construction, utility, transportation and  non-governmental organisational sectors. It reviews the key concepts of sustainability and KM, and challenges associated with managing stakeholders’ knowledge in addressing sustainability issues.

It also presents a conceptual knowledge portal framework for organisations to manage stakeholders’ knowledge in addressing sustainability issues.

The paper concludes that taking the knowledge of stakeholders into account can be particularly useful in addressing sustainability issues.

The key challenges impacting on the successful implementation of knowledge portals to address corporate sustainability issues effectively are lack of leadership, commitment from top management, organisational culture, people and technology.
