During the last years, renewable energy strategies for sustainable development perform as best practices and strategic insights necessary to support large scale organizations’ approach to sustainability. Power purchase agreements (PPAs) enhance the value of such initiatives. A renewable PPA contract delivers green energy efficiently to organizations that seek sustainability benefits. Consequently, various approaches that define PPAs are utilized to motivate both interested parties to participate in such deals. Highlighting sustainability tactics during negotiations and identifying relative impacts during the projects’ implementation are both necessary. Following the methodological approach of this study, open-ended criteria are used to identify vital negotiation pricing patterns that permit practitioners to deliver win–win outcomes. The aim of this research is to introduce a multicriteria decision analysis-based method, namely PROMETHEE, to evaluate the implementation of sustainability-related strategies using PPAs. This paper proposes a method for ranking alternative sustainable energy strategies in order for decision-makers to be able to select the most appropriate PPA structure for an organization.

The lockdown and social distancing policies to reduce COVID-19 spread and perceived safety threats of COVID-19 significantly affected people’s travel behavior. Greece has been suffering from the COVID-19 pandemic, and people’s mobility behavior has been greatly affected. This study aims at: (1) exploring the variations in individuals’ trip frequencies by mode and purpose before and after the COVID-19 outbreak; (2) understanding the effects of individual differences (i.e., sociodemographic details) and perceptions towards COVID-19 (i.e., the perceived threats of COVID-19) on people’s mobility behavior changes after the outbreak; (3) underlining the individuals’ perceptions of the COVID-19 threat on the willingness of public transportation usage. Overall, 403 responses were collected in late 2020. A series of random parameter Probit modeling results reveal multiple individual and perception factors affecting the changes in mobility behavior in Greece. The results from structural equation modeling indicate that perceived COVID-19 threats affect the attitudes and subjective norms towards people’s intentions to use public transportation. The results from this study provide valuable insights for transportation authorities to develop effective strategies to manage traffic during the spread of disease for a possible future epidemic.

The events industry is a project-based industry where sustainable development has been of ever-increasing interest over the last decade. In this regard, the importance of managing risks and delivering quality outcomes in corporate events and the events industry in general cannot be overstated. This paper aims to contribute to the enhancement of project management processes and quality of corporate events, with a focus on risk management. For this purpose, a set of semi-structured interviews with event managers was conducted and thematic analysis was used to qualitatively analyse the research data gathered. Data analysis resulted in the development of a set of tools and methods that have the potential to assist corporate event managers in the project risk management process. This set comprises of a work breakdown structure (WBS) template, a risk breakdown structure (RBS), and a set of risk treatment and mitigation strategies for corporate events. These tools are innovative in the sense that they are based on and correspond to the phases of the event life-cycle rather than individual management domains, have not been developed in unison before, and can be utilized collectively for greater benefits realization.

Even though recent studies designate that sustainability should be integrated in project management, this integration remains a complex issue. Hence, there is a need to develop a new approach that would assess the organizational sustainability and reveal to what extent sustainable project management practices are effective. The aim of this research is to propose a Multi-Criteria Decision Analysis-based method to assess the integration of the sustainability philosophy in large-scale organizations via the utilization of sustainable project management-related indicators. By utilising the proposed approach to compare internal organizational structures, the researchers aim to reveal the sustainability integration level within different business units, in order to allow organizations to make decisions toward sustainable practices. The indicators used in the proposed model are related to key aspects of organizations and they measure how the departments’ staff utilize sustainable project management processes in their construction projects. The case study was conducted in a market-leading design, engineering, and project management consultancy organization. Evaluating organizational sustainability can help organizations target their efforts in certain areas (enhancing sustainable outcomes). It can also facilitate data collection, analysis, and future projections.
