Today, more than ever, achieving sustainability of business activities, intertwining social, economic, and environmental perspectives, is one of the most challenging objectives for companies. Project management processes are no exception. This paper aims to contribute to the current research knowledge through a systematic review of the literature on the integration of project management and sustainability. Specifically, the aim was to clarify the research domains of sustainable project management, and to understand the current state of development and the future research directions. Results indicate that academic literature about this topic is still in its infancy, but that scholars’ attention is growing, opening new research directions. Based on the literature review results, we propose a new conceptual framework linking five key dimensions of sustainable project management: corporate policies and practices, resource management, life cycle orientation, stakeholders’ engagement, and organizational learning.

Green purchase behaviour is receiving a growing attention in the academic community, as understanding it is crucial for the growing number of companies developing and marketing green products. In order to provide a broader and novel picture of the phenomenon, this study extends the widely used Theory of Planned Behaviour (TPB) model in several ways, through a large survey of Italian consumers. First, three dimensions of green purchase behaviour are considered, namely, the willingness to pay a premium price, the green purchase frequency and the green purchase satisfaction. Second, several antecedents are considered simultaneously. Third, new (consumer creativity) or so far marginally studied (materialism and green practices) antecedents are included. Fourth, the mediating roles of green purchase satisfaction and willingness to pay a premium price in the link between the considered antecedents and the frequency of green purchase are investigated.Results show that the three dimensions of green purchase behaviour have different antecedents, so highlighting that green purchase behaviour is a multi-faceted phenomenon that should not be studied as a single general concept. Personal norms and value for money emerged to be very relevant predictors. The significant effects of creativity, materialism and green practices provide evidence that extending the TPB model with these three antecedents is useful to more deeply understand green purchase behaviour. Green purchase satisfaction is the strongest predictor of purchase frequency and mediates the effects of personal norms and value for money.

Purpose The purpose of this study is to analyze the impacts of different policies to address the water supply crisis experienced by the metropolitan region of Sao Paulo during 2013 to 2015 and evaluate the resilience of its water supply system for the coming years. Design/methodology/approach The methodology used in this study is based on the system dynamics simulation paradigm, combined with empirical data obtained from the regional water authority. Findings The results from the simulations suggest that the first layer of sustainability of the water supply in the region strongly depends on how the system’s operator responds to crises, in particular how it balances policies acting on the supply and demand for the resource. Practical implications Severe water crises typically make salient the perception that water is a finite and public resource. Long-term, sustainable management of the system requires a paradigm shift from widespread, old-fashioned beliefs that water is an infinite resource. It also requires active management to increase the system’s preparedness to withstand events caused by climate change. Originality/value This study contributes to the system dynamics and water resource management literature by presenting an integrative model to evaluate the resilience of a particular water supply system. Although there are previous studies on this subject, the present one focuses on the role that the water authority plays in a crisis and especially on a specific combination of policies to address an episode of crisis in a system unprepared for it.

Water is a common good which is fundamental for life and it is only apparently an unlimited resource. In fact, natural water resources are becoming scarce, both due to global climate change but also due to an irresponsible behavior of human beings. Lakes are perhaps among the most delicate aquatic systems due to their limited size. The objective of this paper is to propose a System Dynamics simulation model, employed in a real case study regarding the city of Rome and one of its water reserves, the Bracciano Lake, for the evaluation of environmental impacts resulting from different water exploitation/use strategies and policies, under different climatic and context scenarios. The results indicate that, as the system is currently exposed to a high risk of ecological disaster, the situation might worsen, and the disaster effectively happen; especially if meteorological conditions, like the one experienced in 2017, will occur again in the near future. However, according to certain policies and contextual situations, the risk can be avoided and ultimately mitigated. Nevertheless, models like the one presented in this paper may help water agencies and municipal administrations to explore policies and find solutions to address this fundamental problem, that may become even worst over the next years, given the potential severe consequences deriving from the current global warming trends.
