The growing awareness of the importance of sustainability motivates companies to engage in sustainability practices. However, practising sustainability is challenging since most initiatives are interorganisational in nature. The implementation depends heavily on the capability of multiple organisations within the supply chain, which are not easily assessed. Although a few scholars have proposed a number of frameworks to help organisations identify the required organisational capabilities, none of them is comprehensive enough due to the limited scope. In order to develop a more comprehensive sustainability framework, a complete understanding of organisational capabilities needed for sustainability practices is necessary. This research-in-progress paper therefore aims to synthesize the required key capabilities based on widely implemented sustainability guidelines/standards. The identification of key capabilities is important to understand and explore how ICT can be used by organisations to develop the required sustainability capabilities. This study will potentially contribute to the development of a holistic sustainability framework.
