The purpose of this study is to empirically investigate the impact of institutional pressures, institutional logics and institutional complexity on Sustainable Supply Chain Management (SSCM) practices across mixed public and private sector supply chains.

Multi-case study data were collected from three tiers of food and catering supply chains: the customer/consumer tier; focal public sector UK Universities; and private sector suppliers/contractors.

The findings indicate that: normative and mimetic pressures are more prevalent in focal Universities, compared to suppliers; there is typically no single dominant logic across these supply chains; and the multiplicity of institutional logics (e.g. sustainability logic versus financial logic) increases institutional complexity. Therefore, in the typical case of homogeneity in terms of institutional pressures and logics, e.g. with a dominant sustainability logic throughout the supply chain, radical change in SSCM practices is facilitated. In contrast, in the more typical case when there is heterogeneity, with competing logics at different supply chain tiers, this limits SSCM to more incremental changes in practices.

Research limitations/implications
This study is limited to three tiers of the food and catering supply chains of UK Universities.

Practical implications
To aid in the successful implementation of SSCM, this study suggests a need for managers to develop an initial understanding of the prevailing institutional logics and pressures at different tiers of the supply chain.

Social implications
A number of the SSCM practices studied address social sustainability.

No previous studies have empirically investigated the impact of institutional complexity in the context of SSCM practices across supply chains, involving both mixed public and private sector organisations.
