Purpose: Green supply chain management (GSCM) research is so far dominated by studies focusing on manufacturing companies, while research on retailers is missing. The purpose of this study is to assess the interaction between green in-store activities (environment-related infrastructure and retail in-store processes), GSCM and environmental and economic performance outcomes.Design/methodology/approach: The paper builds on empirical evidence gathered from 190 responses by Croatian food retailers to a self-administered survey. The identified relationships in the conceptual model are tested using partial least squares structural equation modeling.Findings: The results reveal a positive relation between green in-store activities and GSCM in food retailing regarding environmental and economic performance. The relevance of these relationships accrues from the positive association between GSCM and food retailers’ environmental performance, which in turn drives economic performance. It is noteworthy that green supply chain practices drive environmental and then also economic performance.Research limitations/implications: The study extends the application of GSCM to retailing and, therefore, broadens its scope. However, the data collected are based on one country and, thus, should be extended to assess the impact of green retailing practices in the supply chain on environmental and economic performance in other countries.Originality/value: This study, to the best of the authors’ knowledge, is the first empirical analysis on the relationship between green in-store activities and GSCM in the context of food retail. This important link to customers has rarely been explored. Further, the representative sample of food retailers in Croatia is unique as generally data from Central and Eastern European countries are still rare. Finally, the operationalization of GSCM practices into three constructs as green logistics, green purchasing and cooperation with suppliers’ offers conceptual contributions to the GSCM field.

Purpose: This paper identifies, evaluates and structures research that focuses on “collaboration” (C), “trust” (T) and “performance” (P) in the agri-food supply chain (AFSC) and reveals its intellectual foundation. It aims to synthesize research published over a period of 18 years (from 2003 to the beginning of 2020) and provide a platform for practitioners and researchers in their efforts to identify the existing state of work, gaps in current research and future directions in the area of collaboration–trust–performance (CTP) in the AFSC.Design/methodology/approach: Prior to carrying out a bibliometric analysis (BA), literature search was performed, identifying 69 related papers focused on CTP in the AFSC. The content of the papers was further analysed in a systematic literature review (SLR) with regard to the subject area, theoretical lenses, research methodology, supply chain (SC) category and other relevant categories.Findings: CTP in the AFSC are based on a relationship marketing and operations management fundament but show specific particularities. AFSCM is a multi-dimensional design task, and collaboration is considered a necessity, whereas trust significantly affects the AFSC effectiveness. The paper also develops a conceptual CTP model, which shows the interrelations between all identified construct variables, where the authors were able to see also bi-directional relations. Furthermore, the paper presents viable future research opportunities, e.g. focus on organic food chains or multi-actor analysis.Research limitations/implications: Results of the conducted BA refer to the CTP discussion within a preselected number of peer-reviewed academic articles, which are provided by the WoS CC (Web of Science Core Collection) database.Practical implications: CTP measurements within the AFSC context are a relevant subject with increasing academic interest in the area of agricultural economics as well as operations and supply chain management (SCM). Therefore, further studies are necessary to develop the related theory and ascertain the practical implications of collaboration, trust and performance among members in the consistently complex AFSC.Originality/value: CTP have been recognized as important factors for designing a sustainable SCM strategy, particularly in the case of the AFSC. However, although previous studies have addressed the AFSC, there is insufficient knowledge regarding all three pillars (CTP) and how they enable successful AFSCM. The originality of this paper lies in systematically mapping the intellectual base of CTP research and providing path forward for research in AFSCM.

Modern production of packaging is characterized by great choice of packaging materials and the shape of the packaging. There is almost no product on the market that does not have highlighted symbols that should give information about the product and the packaging. Although most consumers pay attention to the symbols, a certain number never checks them, because they consider them irrelevant. The paper investigates consumer perception of the importance of green packaging of food products. A primary research on the sample of 115 respondents has been carried out investigating respondents' behaviour while making the choice on food product packaging. The findings suggest that concern for the environment and less danger for health are two major motives for buying food products in ecologically sustainable packaging. The respondents think that wood and paper have least influence on the environment, while plastic and glass harm the environment the most.

Due to insufficient research on the relationships in the supply chain (SC) of agri-food products, and especially organic food products, the main goal of this study was to examine the perceptions of organic food producers about the importance of collaboration and trust to their performance in the organic food SC. An analysis of previous research has concluded that the important categories of relationship quality (RQ) are the following: appropriate inter-organisational collaboration, effective communication, mutual exchange of information, resource sharing (physical, financial, human, and organisational), willingness to share risks, transparency between partners, relationship quality and commitment, and the presence of trust between partners in the SC. An empirical study based on in-depth interviews was conducted on a sample of six organic food producers in Croatia. The results indicated that the producers’ perceptions of the impact of collaboration and trust on overall performance differs depending on the length of the collaboration with retailers, the types of products, and the percentage of overall sales they sell through retailers. The results of this research can serve as an information base for all stakeholders in the SCs of organic products by encouraging them to participate in activities that will strengthen trust and collaboration as a prerequisite for increasing SC organic food performance.
