Implementing a sustainable business strategy entails assessment of corporate sustainability. In this communication, the Enterprise Sustainability Evaluation Tool (E-SET) is presented and its importance is illustrated. E-SET was developed using the indicators from six global sustainability reporting frameworks and the programming language R. The platform, which can be used for self-assessment and comparison purposes, will provide a comprehensible sustainability score and its graphical representation. Although different sector-specific indicators are proposed in existing literature, E-SET, which is intended to promote sustainability in business practices, incorporates indicators relevant to the three pillars of sustainability. The free and easy tool is expected to help managers of all industries assess their companies, and, based on the results, they would be able to judge their sustainability standing and take remedial steps founded upon the low-scoring sustainability elements. Wider adoption of E-SET will help firms to contribute significantly to national sustainability goals.
