PurposeThe purpose of this paper is to examine how, and by whom, institutional logics are determined in the action of sustainable organisation. The authors analyse a supply chain network structure to understand how multiple stakeholders' perceptions of sustainability emerge into a dominant logic and diffuse across an organisational field.Design/methodology/approachStakeholder network theory provides novel insights into emerging logics within a chocolate supply chain network. Semi-structured interviews with 35 decision-makers were analysed alongside 269 company documents to capture variations in emergent logics. The network was mapped to include 63 nodes and 366 edges to analyse power structure and mechanisms.FindingsThe socio-economic organising principles of sustainable organisation, their sources of power and their logics are identified. Economic and social logics are revealed, yet the dominance of economic logics creates risks to their coexistence. Logics are largely shaped in pre-competitive activities, and resource fitness to collaborative clusters limits access for non-commercial actors.Research limitations/implicationsPowerful firms use network structures and collaborative and concurrent inter-organisational relationships to define and diffuse their conceptualisation of sustainability and restrict competing logics.Originality/valueThis novel study contributes to sustainable supply chain management (SSCM) through presenting the socio-economic logic as a new conceptual framework to understand the action of sustainable organisation. The identification of sophisticated mechanisms of power and hegemonic control in the network opens new research agendas.

In the context of sustainable supply chain management (SSCM), business processes that enable process integration have been explored in a limited way. This paper offers empirical data in response to this gap by evidencing business processes that create sustainability value in the context of the supply chain-and, the role of a phased approach as an enabler. The data are derived from a case study (of 52 organisations) based on a sustainable cocoa supply chain network and the key business processes across that network. Eight business processes were identified as critical to SSCM-strategic planning, design, governance, integration, collaboration, pre-competitive collaboration, stakeholder management, and performance monitoring and evaluation. We demonstrate how business processes become bespoke sustainability processes in relation to SCM through a phased approach of alignment, implementation and maintenance.
