It also examines the evolving role of sustainability in contributing to project success, highlighting both its direct and indirect benefits. Furthermore, this review explores key sustainable project management processes, such as stakeholder management and life-cycle assessment, outlining their associated benefits and challenges. Finally, critical success factors and indicators for implementing sustainability within project frameworks are presented, offering a structured overview of incorporating sustainability into project management.

  • Background and Evolution of Sustainability in Project Management

The initial conceptualizations of sustainability and sustainable development can be traced back to the 1970s, with the growing recognition of the interconnectedness between social, economic, and environmental issues. However, research specifically focusing on its integration into project management practices gained significant attention after the 1992 UN Earth Summit Conference. Following this pivotal event, studies emerged that highlighted the potential impact of projects and managerial practices on crucial sustainable pillars, such as social impact and environmental impact. A subsequent critical juncture was the 2008 IPMA World Congress, where the opening keynote demanded "accountability for sustainability" from project managers. This call initiated another significant wave of research, leading to more contemporary studies on sustainable project management. As the imperative for sustainable practices intensifies across all sectors, the need to research and introduce effective methodologies to achieve this integration also grows. Incorporating sustainability into project management transcends merely addressing environmental concerns; it is about ensuring the long-term viability of both individual projects and the organizations that undertake them. A sustainable approach promotes the efficient utilization of resources, minimizes waste generation, and reduces the environmental footprint of projects, while concurrently considering social and economic factors. This holistic perspective, commonly referred to as the triple bottom line, ensures that projects not only meet their financial objectives but also contribute positively to society and the environment. This is particularly vital as stakeholders, including investors, regulators, and communities, increasingly hold organizations accountable for their environmental and social impact. Projects that effectively integrate sustainability can enhance a company’s reputation, foster greater stakeholder engagement, and potentially unlock new market opportunities driven by responsible innovation. Moreover, the adoption of sustainability in project management can provide a significant competitive advantage, leading to long-term cost reductions through improved resource efficiency and effective risk mitigation, especially in industries susceptible to regulatory changes or environmental risks. Projects that embed sustainability principles from their inception are also more likely to exhibit adaptability to future challenges, such as climate change and resource scarcity. This adaptability not only enhances the success rate of individual projects but also contributes to the overall resilience and agility of the organization. Consequently, sustainability is no longer a peripheral consideration but has become a core competency within project management, aligning with global sustainability agendas like the United Nations Sustainable Development Goals (SDGs) and establishing a foundation for sustainable growth. Research in sustainable project management is continuously evolving, with a focus on developing methodologies and frameworks that enable organizations to achieve their objectives without compromising the ability of future generations to meet their own needs.

III. Defining Sustainability in Project Management

Sustainability in project management is fundamentally rooted in the concept of sustainable development, defined by the World Commission on Environment and Development as "a process of change in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are made consistent with future as well as present needs". This overarching concept is often operationalized through the Triple Bottom Line (TBL), which encompasses three key and interconnected dimensions: environmental, economic, and social. The environmental dimension concentrates on the preservation of the natural environment and the responsible use of natural resources. This includes minimizing pollution, conserving biodiversity, and utilizing resources efficiently throughout the project lifecycle. The economic dimension emphasizes maintaining financial stability and generating economic value. In the context of projects, this extends beyond mere profitability to include aspects like cost efficiency over the long term, creation of local economic opportunities, and the economic viability of the project's outcomes. The social dimension centers on building strong social relationships and promoting social well-being. This involves considering the impact of the project on communities, ensuring fair labor practices, promoting inclusivity, and fostering positive stakeholder relationships. Reviews of existing literature reveal several common points in defining sustainability within project management practices. These include: the importance of minimizing resource use throughout the project’s life-cycle, the necessity of considering sustainability throughout the entire lifecycle of a project, the integration of environmental, social, and economic aspects to balance these three pillars of sustainability, and the need for active and transparent stakeholder involvement. However, some aspects appear to be less emphasized or occasionally overlooked in these definitions. These include a broader view into the project and further defining sustainability within the key project management domains or practices, as well as placing more emphasis on organizational learning and adaptive management.

  • Expanding the Triple Bottom Line in Project Management

While the traditional TBL framework provides a fundamental structure for understanding sustainability, its application within the specific context of project management necessitates an expansion and contextualization of its core pillars. Based on a synthesis of previous research, the economic, social, and environmental pillars of sustainability can be further elaborated into more specific project management-related aspects. The economic pillar expands to include: stakeholders’ management, recognizing the interconnectedness of corporate sustainability with how companies conduct their business and meet stakeholder expectations; political and public management, acknowledging the influence of institutions, public entities, and political organizations on the business environment; engagement and innovation, encompassing key indicators such as leadership, commitment, productivity, and innovation within the project context; economic performance, emphasizing the direct positive influence of consistently delivering value through projects; company–customer relationship management, recognizing the crucial role of customer relationships in a company's growth; the value chain, viewing it as a business model that outlines the entire process of creating a product or service; quality management, referring to the comprehensive management of activities and responsibilities to achieve a specified level of perfection; and productivity, often defined as the ratio of output to input volume, reflecting process efficiency. The social pillar expands to incorporate: decision-making, pertaining to the ability of individuals to exert influence and bring about change within a system; learning, recognizing the importance of acquiring knowledge and innovative solutions for long-term system sustainability; meaning making, highlighting how agile project management can foster an organizational culture that empowers innovation; self-organization, where optimal project elements emerge from self-organizing teams; trust, playing a pivotal role in employee motivation and self-organization; collaboration/communication, widely recognized as central elements of Agile Project Management; motivation, encouraged by well-defined and systematic approaches; stress reduction, positively impacted by generating essential project documentation; and commitment/ownership, fostering responsibility and dedication within the project team. The environmental pillar expands to include: environmental resource, referring to the natural resources used to obtain goods and services; legislation, highlighting the importance of adhering to legal requirements and standards like ISO 14004; environmental involvement, recognizing sustainable development as a significant factor influencing business strategies; certifications and environmental education, emphasizing the role of knowledge acquisition in environmental sustainability; sustainable consumption of environmental resources, involving the efficient management of natural resources; environmental policy and management system, a formal statement outlining a company's environmental objectives; and commitment, scope and dissemination of environmental policies and criteria, crucial for environmental protection and resource management. It is noteworthy that an element such as risk management and risk mitigation, which could play a crucial role in both environmental and economic sustainability, might be overlooked in some of these expansions.

  • The Role of Sustainability in Project Management

Research reveals diverse interpretations of the role of sustainability within the context of project management. Studies have presented different and sometimes even opposing views on its significance and function. Friedrich's research identified three main evolving roles of sustainability in project management: initially viewed as a roadblock or constraint that might impede traditional project goals; subsequently recognized as an asset that can provide benefits such as enhanced reputation and stakeholder engagement; and finally, emerging as a core project objective that significantly influences decision-making throughout the project lifecycle. This evolution signifies a paradigm shift where project decisions, traditionally driven primarily by cost, time, and quality considerations, now increasingly need to incorporate sustainable objectives, even if these objectives sometimes conflict with traditional project goals. Conversely, numerous studies have also highlighted the crucial role of project management and its associated skills in ensuring the success of project sustainability. Skills such as effective communication, comprehensive project planning, strong leadership, and diligent project evaluation and monitoring are identified as critical enablers for achieving sustainable project outcomes.

  • Sustainable Project Management Processes

Many widely accepted project management standards, such as the PMBok of PMI and ISO 21500, are fundamentally based on process frameworks. Consequently, a process-based approach has been frequently utilized in studies aiming to integrate sustainability into project management. Research, such as that illustrated in the source, indicates that the project management processes most frequently mentioned in the context of sustainability are: Stakeholder management, Life cycle management, Assessment, and Decision-making. Integrating sustainability considerations into these processes can yield several benefits for projects. Enhanced stakeholder management, which prioritizes open communication and transparency, can increase stakeholder satisfaction by fostering collaboration and trust. Incorporating a lifecycle perspective allows for a focus on waste management and the efficient use of resources throughout the project's duration, minimizing environmental impact. Sustainability assessments, such as environmental impact assessments, help projects comply with relevant regulations, thereby avoiding potential legal issues. Finally, integrating sustainable criteria into decision-making processes leads to more informed and responsible choices. However, the application of sustainable principles in project management is not without its challenges. These challenges can be broadly categorized as: planning-related challenges, involving difficulties in integrating long-term sustainability goals with short-term project deliverables; project-related challenges, arising from the complexities of incorporating sustainable practices, potentially leading to additional steps, constraints, or trade-offs, and thus possible delays or increased costs; client-related challenges, where differing client priorities or a lack of understanding of sustainability can hinder the alignment of project goals with sustainable practices, particularly when clients prioritize cost and speed; project team-related challenges, stemming from a lack of necessary knowledge, skills, or motivation within the project team to effectively implement sustainability; labor-related challenges, which involve ensuring labor practices align with sustainability goals, such as fair labor standards and safety, especially in complex supply chains; and various external challenges.

VII. Sustainable Indicators and Critical Success Factors

A critical aspect of integrating sustainability into project management is the identification and application of sustainable indicators and critical success factors (CSFs). Implementing a well-defined set of indicators is essential for monitoring the progress towards meeting sustainable targets throughout the project lifecycle. CSFs, on the other hand, represent the minimum essential conditions that must be in place for a project to achieve its desired sustainable outcomes and effectively mitigate significant risks. Numerous studies have focused on defining both indicators and CSFs for sustainable projects. Banihashemi et al. synthesized sustainable CSFs into a multi-stage process, encompassing identification, evaluation, commitment, preparation in organization, preparation on project, and implementation. In contrast, Martens & Carvalho identified four main types of CSFs: Environmental policies and resources saving, Economics and competitive advantage, Stakeholders management (society, employee, suppliers and contractors), and Sustainable innovation business model, further breaking these down into sub-factors. Several studies have also focused on developing sustainable project indicators, often presenting indicators aligned with each of the TBL pillars. For instance, research on sustainable indicators for construction projects has identified principal considerations such as: sustainable use of natural resources, energy efficiency, eco-efficiency, efficient allocation of resources, environmental impact assessment project report, updated environmental construction methods and technologies, economic/financial performance, cost management plan, environmental/economics accounting, and environmental education and training.

VIII. Sustainability Principles in Project Management

Beyond the TBL framework, several studies have proposed additional principles or 'dimensions' of sustainability that hold specific relevance for project management. Research such as that by Silvius & Schipper and Goedknegt & Silvius has identified multiple dimensions beyond the traditional three pillars, as depicted in the source. These studies also explore the potential influence of these broader sustainability dimensions on various project management roles, including project managers, clients, sponsors, and senior management.

  • Sustainability in Project Management Knowledge Domains

Project management standards, such as the PMBOK Guide, typically divide project management practices into multiple knowledge domains. However, the source notes that there has been limited research specifically examining the integration of sustainability within these separate project management domains. The majority of the research in this area has predominantly focused on project stakeholder management and project risk management. Table 2 in the source provides a summary of different studies categorized by knowledge domains, including schedule, resource, cost, risk, procurement, and stakeholder management. Notably, the source identifies a research gap in the integration of sustainability within the knowledge domains of project integration management and project communications management, potentially due to the inherent fundamental nature of these domains, making their direct alignment with sustainable goals challenging.

  • Points of Agreement, Debate, and Gaps in the Research

The reviewed literature generally agrees on the increasing importance of integrating sustainability into project management and the relevance of the Triple Bottom Line framework as a foundational concept. However, debates persist regarding the precise definition and effective practical implementation of sustainability principles within diverse project contexts. A significant research gap exists in the exploration of sustainability integration within the project management knowledge domains of project integration management, project communications management, project scope management, and project quality management. Furthermore, the literature reveals a need for more research focused on: various project contexts and different types of projects; the examination of sustainability across different project management phases (planning, execution, etc.); the study of success factors and their effective measurement in sustainable project management, as well as the impact of sustainability on overall project success; in-depth studies on the factors within separate project management domains or different project contexts for more specific findings; dedicated research on each of the TBL pillars and their extensions within the project management context; examining the effect of sustainability on project team productivity; empirical studies of projects based on the various presented theories of sustainability; proposing practical frameworks to manage and balance sustainable goals with traditional project management goals (cost, time, quality); examining the characteristics, leadership styles, and competencies of project managers in the field of sustainable development and project management; further study on sustainable project management domains that have received limited research attention; and proposing frameworks for more effectively integrating sustainability into project management education and training programs and measuring its impact on project performance and the achievement of sustainable goals.

  • Methodological Approaches in the Reviewed Literature
