The purpose of this paper is to delineate a green supply-chain performance measurement framework using an intra-organisational Collaborative Decision-Making (CDM) approach. A fuzzy-Analytic Network Process (ANP) based Green Balanced Scorecard (GrBSc) has been used within the CDM approach. CDM aids in arriving at a consistent, accurate and timely data flow across all cross-functional areas of a business thereby providing real-time information for the evaluation, control and improvement of processes, products and services so as to meet both business objectives and rapidly changing customer needs. A green causal relationship is established and linked to the fuzzy-ANP approach. The causal relationship involves organisational commitment, eco-design, green supply-chain process, social performance and sustainable performance constructs. Sub-constructs and sub-sub-constructs are also identified and linked to the causal relationship to form a network. The fuzzy-ANP approach suitably handles the vagueness of the linguistics information of the CDM approach. The CDM approach is implemented in a UK-based carpet manufacturing firm. The performance measurement approach, in addition to the traditional financial performance and accounting measures, aids in making decisions of the firm in regard to the overall organisational goals. The implemented approach assists the firm in identifying further requirements of the collaborative data across the supply-chain and information about customers and markets. Overall, the CDM-based GrBSc approach assists managers in deciding if the suppliers’ performances meet the industry and environment standards and the human resource is effective.
