Abstract [en]

Purpose – The purpose of this study is to measure the gaps between the engagements of shippers (i.e.logistics buyers) and logistics service providers (LSPs) in different green logistics practices (GLPs)throughout the key phases of the logistics purchasing process: request for proposal, negotiations, contractingand execution.

Design/methodology/approach – A large-scale survey of shippers and LSPs in Sweden was conducted.Respondents were 331 firms (169 shippers, 162 LSPs). Mean values of the actors’ perceptions were analysedusing independent- and paired sample t-tests.

Findings – While this study supports previous research indicating that LSPs engage more extensively inselling GLPs than shippers do in buying them, it shows that this conclusion does not uniformly apply to allGLPs nor all purchasing phases. Three patterns emerged for the gaps between the actors’ buying-sellingengagements throughout the purchasing process: (1) steady and wide gaps, (2) steady and narrow gaps and(3) emergent gaps. Distinct GLPs were associated with each pattern. It is also shown that the prioritisation ofGLPs is fairly aligned between shippers and LSPs.

Research limitations/implications – This study contributes to the green logistics purchasing literature bysystematically and simultaneously creating three types of distinction, between (1) shippers and LSPs, (2)different GLPs and (3) different logistics purchasing phases. Future studies could replicate the analysis incountries other than Sweden.

Practical implications – Managers of shipper/LSP firms learn tips to spot the GLPs that their partnersprioritise, enabling them to modify their purchasing/marketing strategies accordingly.

Originality/value – The three types of distinction represent a novel approach in the green logisticspurchasing literature.

Abstract [en]

Purpose: The green logistics literature remains undecided on how collaboration between shippers (i.e. logistics buyers) and logistics service providers (LSPs) may facilitate green logistics practices (GLPs). This paper identifies two types of collaboration mechanisms, relation specific and knowledge sharing, to systematically examine their influence on facilitating the different types of GLPs – as seen by shippers versus LSPs. Design/methodology/approach: Survey responses of 169 shippers and 162 LSPs in Sweden were collected and analysed using exploratory- and confirmatory factor analysis, followed by multiple regression analysis. Findings: The findings reveal that neither of the actors consistently favour a certain type of collaboration mechanisms for facilitating all types of GLPs. Although it was found that both actors share the same view on the role of collaboration mechanisms for some GLPs, their views took contrasting forms for others. Research limitations/implications: This study contributes to the green logistics literature by incorporating a trilateral distinction to present collaboration recommendations for GLPs, based on (1) the collaboration mechanism at play, (2) the actor's perspective and (3) the GLP in question. Practical implications: Insights are offered to managers at shipper/LSP firms to apply the right (“fit for purpose”) collaboration mechanisms in their relationships with their logistics partners with respect to the desired GLPs. Originality/value: This is one of the first large-scale studies to systematically reveal in what way collaboration can facilitate the different types of GLPs.

Abstract [en]

This paper explores shippers’ (i.e. logistics buyers) and logistics service providers’ (LSPs) perceptions of green concerns under diverse contractual settings during the key phases of the lo-gistics purchasing process: request for proposal, negotiations, contracting and execution. Accordingly, it derives recommendations that could increase the actors’ inter- and intra-organisational alignment on green targets throughout these phases. Empirical data are obtained from eight individual cases of three shippers and five LSPs, representing the buyer/seller roles within logistics arrangements. Contrary to previous literature holding the view that setting more green demands by shippers would guarantee green outcomes, the findings show that shippers’ green demands may hinder green logistics applications due to impediments to LSPs’ asset-sharing strategies. Also, a deadlock situation is revealed in the negotiations phase, where both actors await each other to introduce additional demands/offers - calling for further regulatory intervention to release this deadlock. Moreover, this paper shows how a mismatch of interests in contractual periods between shippers and LSPs can obstruct green investments - signalling that the green criterion is not the decisive factor in shaping shippers’ outsourcing strategies. The findings also stress a lack of follow-up efforts by shippers on green measures that were specified pre-contract, attributing this to contrasting intra-organisational objectives within shippers’ firms. This paper contributes to the green logistics purchasing literature by revealing how different contractual settings play an important role in shaping shippers’/LSPs’ perceptions of green concerns during the logistics purchasing process. Further, it is one of the first studies to provide phase-specific recommendations to increase the actors’ alignment on green targets.

Abstract [en]

This paper applies institutional theory to analyse the institutional pressures (regulatory, market, competitive) experienced by two actors within supply chains: shippers (i.e. logistics buyers) and logistics service providers (LSPs). Both actors are subject to institutional pressures to adopt green supply chain management practices, which could drive shippers to purchase green logistics services from LSPs, and LSPs to provide them. Also, the two actors are influenced by various factors that moderate the level of pressures on them and the responses they undertake. This study examines these pressures and moderators in detail to analyse how they influence green logistics purchasing/providing decisions. Empirical data were obtained from eight individual cases of three shippers and five LSPs. Accordingly, we compare these pressures and moderators based on the actors’ different roles in the supply chain. The findings aim to contribute to advancing the theory through (i) incorporating the roles of the moderating factors and (ii) providing further applications within specific shipper-LSP contexts. Further, this paper aims to assist managers within shipper and LSP organisations by demonstrating how their firm and market characteristics moderate the pressures exerted on them to buy or provide green logistics services, while providing insights on issues influencing their responsiveness.

Abstract [en]

Purpose: Greenhouse gases, such as CO2, are heating up the planet and causing sea levels to rise, and the logistics industry, although vital for contemporary society, it is also a main contributor to the problem. Shippers and logistics service providers (LSPs=) can reduce their emissions by implementing green logistics practices, but these actors also need keep a close eye on costs. The purpose of this paper is to analyse the impact of different green logistics practices on logistics emissions and cost efficiency.

Methodology: The paper is based on survey, with responses from 169 shippers and 162 LSPs in Sweden. Commonly used methods such as correlation-, principal component- and multiple regression analyses have been employed.

Findings: The findings reveal that some types of green logistics practices are strongly associated with reduced emissions, whereas others have less of an impact. Moreover, the results provide no evidence of a trade-off situation, i.e. a situation where green logistics practices would reduce emission while increasing costs.

Research limitations/implications: This paper contributes to the discussion on green logistics practices, and particularly on whether going green is costing more. This paper is based on self-reported emissions and cost-efficiency. It is recommended that future studies look at real emission data that may be available from companies’ annual reports.

Practical and Social implications: The findings provide insights to practitioners and policymakers who are seeking to reduce emissions from logistics. While it may be too optimistic to assume that cost efficiency will improve while becoming greener, there seems to be economic down-side to investing in green practices either.

Originality: Research is thus needed to simultaneously assess the relative impact of different green logistics practices on both emissions and on cost efficiency in logistics. This paper aims to fill this gap

Abstract [en]

The logistics and transport industry places a heavy load on the environment, causing various harms such as air pollution, global warming and resource depletion. The logistics and supply chain management literature assigns the largest share of responsibility for alleviating such harms to two supply chain actors: shippers (i.e., logistics buyers) and logistics service providers (LSPs), which motivated focusing on them in this thesis. Specifically, the purpose of this thesis is to investigate the engagements of shippers and LSPs in different green logistics practices (GLPs) throughout the logistics purchasing process, and to propose improvements for such engagements by their interactions.

Three research questions drive this investigation. The first question handles comparing the drivers (i.e., institutional pressures) for shippers to purchase GLPs and for LSPs to provide them—to reveal how this ‘one-tier network’ is driven as a whole. The second question aims to describe how shippers and LSPs engage in the different GLPs throughout the logistics purchasing process (across its four phases: request for proposal, negotiations, contracting and execution) and why such engagement takes place as it does. The third question aims to propose improvements for shippers’ and LSPs’ engagements in the different GLPs throughout the process—by enacting different degrees of interactions (cooperation vs. collaboration). A methodological triangulation approach is used to answer these questions, based on five papers that are extracted from three studies: a single case (shipper-LSP dyad), a multiple case (3 shippers, 5 LSPs) and a survey (169 shippers, 162 LSPs).

The findings reveal a lack of direct regulatory, market and competitive pressures on shippers to purchase GLPs. These are compared to existing (yet insufficient) regulatory pressure, effective market pressure and emergent competitive pressure on LSPs to provide GLPs. The findings also reveal gaps between the actors’ purchasing-providing engagements in GLPs across the purchasing process, which followed three patterns: steady & wide, steady & narrow and emergent. Distinct GLPs are associated with each pattern, and detailed explanations are presented for these associations based on the characteristics of each GLP . Further, the findings propose paths to improve the actors’ engagements in GLPs across the process, based on the gap pattern for each GLP and the degrees of shipper-LSP interactions required for it (cooperation vs. collaboration).

This thesis contributes to the body of knowledge through systematically incorporating a trilateral actor-, phase- and GLP-specific distinction into the green logistics purchasing discussion. Also, it transcends the descriptive (and general) level of analysis of shippers’ and LSPs’ green engagements during the logistics purchasing process, by: (i) explaining why such engagements occur as they do and (ii) providing recommendations that could actually improve these engagements. Insights are offered to managers at shipper/LSP firms to assist them in modifying their purchasing/marketing strategies throughout the purchasing process with respect to specifically targeted GLPs. Insights are also offered to policymakers to set suitable regulations on both actors to support ‘greening’ logistics networks.

Findings: While our findings conform with previous studies asserting that LSPs engage more extensively in green logistics practices than shippers do, we show that such situation is not uniformly applicable to all practices nor all purchasing phases; three patterns emerged that depict the gapsbetween the actors’ engagements along the process: (i) steady and wide gap, (ii) steady and narrow gap, and (iii) emergent gap – each gap is associated with distinct practices.

Research limitations/implications: Contributing to the green logistics purchasing literature by creating three types of distinctions: (i) between shippers and LSPs, (ii) between different green logistics practices, and (iii) between different logistics purchasing phases. The survey covered actors in Sweden only, future studies could replicate the analysis in other countries.

Practical implications: Insights are offered for managers within shipper/LSP firms to help them in spotting the green practices that are least focused upon by their partners, thus enabling them to modify their purchasing/marketing strategies accordingly.

Social implications: Potentially contributing in reducing the carbon footprint of the logistics industry.

Original/value: The three types of distinctions is a novel outset within the contract logistics and green supply chain management bodies of literature.

Abstract [en]

The contract logistics literature implicitly suggests that establishing advanced relationships between shippers (logistics buyers) and logistics service providers (LSPs) plays a role in facilitating green logistics practices. We systematically test this claim through surveying 335 companies (170 shippers; 165 LSPs) in Sweden. Using factor- and multiple regression analyses, we confirm that implementing green logistics practices is influenced by advanced relationships settings, but not all practices adhere to this. Also, a distinction is made on whether relationship advancement is expressed by the contract design or the degree of integration between the partners; the former better explains the implementation of the practices.

Abstract [en]

The logistics industry causes various harms to the environment. The literature assigns the main responsibility for alleviating such harms to two supply chain actors: shippers (logistics buyers) and logistics service providers (LSPs), which motivated studying them in this thesis. Specifically, this thesis explores and identifies how green logistics practices can be facilitated through aligning both actors throughout the different phases of their relationships. Two studies are compiled. The first study is based on five distinct cases -- three shippers and five LSPs, providing the basis for two papers: (i) one that analyses the institutional pressures (regulatory, market, competitive) on shippers to purchase green logistics services, and on LSPs to provide these services, and (ii) one that investigates the two actors’ stances on environmental concerns in the four key logistics purchasing phases (request for proposal, negotiations, contracting, execution), while proposing ways to align their efforts along such phases. The second study covers a single case of a dyadic relationship between a shipper and its LSP, handling enhancing logistics performance (cost efficiency, on-time delivery) in the early stages of their relationship. The findings indicate a general lack of regulatory pressure in driving shippers and LSPs to engage in green logistics, contrasted by a long-term influence of competitive pressure and a prevalent influence of market pressure. It was also found that both actors must put substantial efforts in the beginning of their relationships to reach a mutual business understanding, allowing performance and green enhancements. In the execution, it was found that both partners should regularly communicate performance metrics while modifying working standards, which would also support their green practices. For practitioners, insights are offered to align shippers’ and LSPs’ efforts within their relationships to attain positive performance and green outcomes.

Abstract [en]

This study aims to identify the main drivers for engaging in sustainability practices in shipper-third-party logistics (3PL) provider relationships, and differentiate between both actors’ perspectives based on their roles within 3PL arrangements. A literature review is conducted to outline the main drivers for each actor among different academic themes. Then, data obtained from an explorative multiple-case study involving two large shippers and two large 3PL providers is illustrated and critically analysed. The drivers are sorted in a matrix that demonstrates nine categories to enable distinguishing both actors’ perceptions accurately. Detecting variations among the actors’ viewpoints on the drivers enables future research to focus on aligning both actors together to realise positive sustainable change.
