Green productivity indexing

Purpose - The purpose of the paper is to illustrate an approach for developing a framework of indicators for integrating environmental protection into corporate performance. This paper also highlights Green Productivity Index (GPI) of the Continuous Improvement (CI) performed in a foundry casting, which includes both economic and environmental performances. Design/methodology/approach - In the paper data were collected from a foundry and used for developing indicators and Green Productivity Index (GPI). Mass balance concept was used for quantification of environmental indicators. Findings - The paper finds the approach adopted will provide a clear guidance for developing indicator and GPI to various types of industries. A casting case indicates that the GPI can be used as an actionable feedback for leadership to make effective decisions. Research limitations/implications - This research in this paper developed a framework of indicators for measuring direct environmental impact from the foundry, while indirect environmental impact due to electricity consumed has yet to be performed. Limited external validity of the indicator framework, as the analysis was performed in a single foundry. Practical implications - The paper relies on a unique foundry data. Environmental indicators may vary, since the melting furnace used for melting metal and type of molding process used for making molds may vary from one foundry to another. Originality/value - This paper is a holistic approach of combining theory and practical ideas to cover the scope of sustainable development. From a research perspective, it establishes a framework of indicators for the integration of environment into foundry and creates new research and application opportunities to other pollution‐intensive industries. From a practical perspective,the framework of indicators developed to this point provides a guideline of immediate applicability.
