This article aims to optimise energy use and consumption by integrating Lean Six Sigma methodology with the ISO 50001 energy management system standard in an Irish dairy plant operation.

This work utilised Lean Six Sigma methodology to identify methods to measure and optimise energy consumption. The authors use a single descriptive case study in an Irish dairy as the methodology to explain how DMAIC was applied to reduce energy consumption.

The replacement of heavy oil with liquid natural gas in combination with the new design of steam boilers led to a CO₂ footprint reduction of almost 50%.

A further longitudinal study would be useful to measure and monitor the energy management system progress and carry out more case studies on LSS integration with energy management systems across the dairy industry.

The novelty of this study is the application of LSS in the dairy sector as an enabler of a greater energy-efficient facility, as well as the testing of the DMAIC approach to meet a key objective for ISO 50001 accreditation.

The purpose of this paper is to develop an integrated theoretical framework for energy security concept and to shed light on the policies and strategies applied by the European Union countries to confront the challenges that faces them.

The research paper uses Regional Security complexes theory, which mainly developed in Copenhagen school for security studies, that founded by Barry Buzan. This school tried to clarify the untraditional security aspects, through expanding its scope by adding new dimensions than military perspective.

Despite the consolidated efforts exerted by the European Union to assure safe levels of energy security, and their continuous pursuit to be liberated from Russian energy over dependence, but the results are still limited.

The value of this research paper stems from the fact that it encompass the theoretical aspect by shedding light on all the developments occurred to energy security concept, in addition to the Empirical side, by analyzing various European energy security challenges and their confrontation strategies.

Due to the globalization of trade, hundreds of millions containers pass every year through world ports. Such a situation is extremely challenging in terms of securing freight transport operations. However, costs and lead-times are still very important components of supply chains' performance models. Therefore, the drive for enhanced safety and security cannot be made at the expense of these other two factors of competitiveness, and the processes implemented by the global supply chain links, including the maritime port one, should tend to a joint optimization of trade facilitation and operational safety / security.

The research on which this paper feeds back falls within the frame of this mixed performance requirement. More specifically, the paper presents a decision-support system dedicated to managing the risks associated with land and maritime container transportation; this system is based on the modeling of the knowledge of a group of experts, and covers the three phases of risk identification, assessment and avoidance / mitigation.

As the Malacca and Singapore Straits are part of the shortest route between Europe and Asia any impedance to shipping has serious commercial and strategic repercussions. What would be the consequences to tankers and container shipping if access was restricted or prevented? This issue is addressed by examining the costs of using alternative tanker routes to the Straits and the flow-on consequences of removing a mega-hub port from the container-shipping network. The analysis highlights differences between tanker shipping, where the ship itself is the prime unit of interest, and container shipping, where the door-to-door network is of paramount importance.

Government-owned companies (GOCs), such as ports, have engaged in efforts to become more sustainable. Most of such efforts have been technological and policy ones and mainly focusing on the environment, with limited research on organisational change management. This paper aims to provide insights into how ports have been addressing sustainability change forces and pressures.

Twelve semi-structured interviews were conducted with top-level directors and sustainability managers, representing ports across Europe’s maritime regions and a range of port types and sizes. The interviews were analysed using grounded theory’s constant comparative analysis.

The findings highlighted that the ports’ success in their process to become more sustainable depends on how they take advantage of the thrust forces and reduce the drag ones. The findings serve to develop the “ports’ sustainability change management framework”, with five stages: reactive, proactive, transactive, interactive, and sustainable port.

Ports, and other GOCs, should capitalise on their private–public nature in their contribution to making societies more sustainable by adopting a holistic perspective and interactive changes.

This paper provides a dynamic perspective on corporate sustainability efforts, particularly on GOCs, through organisational change management complementing technocentric and managerial approaches.

This study aims to analyze information on vessel traffic between the two Koreas with a probability distribution for each route/vessel type. The study will then conduct an estimate for maritime transport patterns of inter-Korean trade in the future. To analyze the flow of inter-Korean coastal shipping, this study conducted visualization analysis of shipping status between North and South Korea by year, ship type, and port using navigation data of three years from Port Logistics Information System (Port-MIS) sources during 2006 to 2008, which saw the most active exchanges between the two governments. Also, this study analyzes shipping status between the two governments as a probability distribution for each port and provides the prospects for future maritime transport for inter-Korean trade by means of Bayesian Networks and simulation. The results of the analysis are as follows: i) when North-South routes are reopened, the import volume for sand from North Korea will be increased; ii) investment in the modernization of ports in North Korea is required so that shipping companies can generate profit through economies of scale; iii) the number of the operating vessels including container ships between the two governments is expected to increase like when the tensions and conflict on the Korean Peninsula was release, especially between Busan port in South Korea and Nampo port in North Korea; and iv) among container ships, transshipment containers imported and exported through Busan Port will be shipped to North Korea by feeder transportation.

This study investigates how cruise corporations, which have shown consistent and high growth rates in recent years, address the Sustainable Development Goal 17 (SDG17) “Partnership for the Goals” to meet the UN 2030 Agenda. This study aims to fill the existent gap in the literature, as also highlighted by practitioners in the First Research Conference on Tourism, through the lens of stakeholder theory.

This study focuses on the analysis of partnerships and collaborative governance of cruise corporations’ endeavours to meet the UN 2030 Agenda. This study is supported by the sustainability disclosure framework and stakeholder theory, based on the dependence of resources and descriptive and instrumental approaches to describe, analyse and map, through multi-stakeholder partnerships, the sustainability initiatives and practices adopted by cruise corporations. A systematic manual content analysis has been developed on sustainability reporting published by corporations.

According to the descriptive and instrumental approaches and the dependence resources construct of the stakeholder theory, this study highlights the typology and nature of partnerships with SDGs, and their strategic role in achieving them, although cruise corporations do not highlight in their sustainability reporting the measures of effectiveness regarding the relationship between single partnerships and targets reached for each SDG.

Recommendations at the managerial level are put forward to support cruise corporations’ initiatives and practices to meet UN 2030 Agenda. This study suggests to governors of corporations the cooperation between the cruise industry and institutions at the local, national and international levels for promoting institutional interventions at the infrastructure and economic level.

This study provides further insights into the under-researched topic of sustainability disclosure within the cruise industry, adopting the lens of stakeholder theory from the partnerships’ perspective. To the best of the authors’ knowledge, this is the first study to adopt the analysis of the SDG practices under the lens of the stakeholder theory, based on the dependence of resources and descriptive and instrumental approaches to identify, map and analyse the multi-stakeholder partnerships as an enabling key to meet UN 2030 Agenda in the cruise industry.

Ports create harmful effects on their adjacent population because ships discharge noxious gases like SO_X, NO_X, and particulate matter (PM). To tackle this problem, some ports started to control emission through regulations such as Emission Control Areas (ECA) and Reduced Speed Zone (RSZ). This paper estimates the social cost of ship emission and eco-efficiency at the Port of Incheon (POI). We further examine how the ECA and RSZ designation can reduce the social cost. The estimation is based on the activity-based approach, where ship type, engine, and movement are used to measure fuel consumption and then emission. Results suggest that the social cost of ship emission at the POI amounts to $90,805,478. The eco-efficiency of the POI, compared to the one at the Port of Las Palmas in another study, is substantially better. Under RSZ, the corresponding emission abatement values are $4,485,308, $2,642,009 and $21,932,435 from SO₂, NO_X and PM reduction, respectively. If 1.0% and 0.1% sulfur fuel are used complying with rules of the ECA, the social cost savings amount to $8,174,947 and $12,868,842 from SO₂ reduction.

This paper aims to explore how the Italian wine industry discloses corporate social responsibility (CSR) practices and quality certifications and the corresponding determinants via websites. The study also aims to investigate the relationship between CSR practices and financial performance. The information consistency between the quality certificates reported on corporate websites and official database statements is also explored. Lastly, the paper investigates how the relationship between the size of wineries and CSR disclosure changes according to firms' geographic location.

This paper analyses CSR corporate communication via the websites of a sample of Italian wineries by adjusting the theoretical framework developed by Amran (2012) to the wine sector's peculiarities. Moreover, a cross-certification analysis and a moderation analysis were performed to fulfil the purpose of the research.

The analysis revealed the extensive use of CSR disclosure via websites. It was found that company size positively affects CSR disclosure and Quality Certification Disclosure (QCD), while geographic location slightly moderates the relationship between the two variables. In addition, a negative relationship between CSR disclosure and corporate financial performance and its reverse causality emerged. Moreover, for most wineries, information consistency between the quality certificates reported on corporate websites and official database statements was observed.

The study's main limitation is that the search process was performed during lockdown. Therefore, the examined issues could change in the near future due to the shift in priorities that the COVID-19 pandemic is determining.

The results can help managers implement CSR disclosure and QCD practices to enhance stakeholder legitimacy and enable their companies to compete in strongly competitive international markets.

The paper represents the first study investigating online QCD and its consistency in the Italian wine sector.
