Investors are currently obliged to take environment, social, and governance (ESG) issues into consideration as part of their fiduciary duty. As such, it becomes increasingly important to identify sustainable investments that also hold financial value. A sector where this is especially underdeveloped is real estate. This has a lot to do with the obfuscated conceptualization of ESG. The article identifies key gaps in the literature and practice and provides a framework to further the understanding of how ESG factors can add societal and financial value in the real estate sector. A key premise of the article is that the user in the building is grossly overlooked. Drawing on insights from behavioral social science and environmental psychology, the paper explains the role of the user in improving buildings’ ESG, also taking into account the investment value. To conclude, the article makes the case that the transition to user-centered smart real estate is the solution to improving both the environmental (E) and social (S) sustainability of buildings, as well as their investment value. Therefore, practitioners and academics are encouraged to critically evaluate and contextualize the ESG framework they are using as well as the extent to which users are considered and smart technology is employed.

Carbon capture and utilization (CCU) is one of the key technologies that may help to reduce industrial emissions. However, the deployment of CCU is hampered by various barriers, including high levels of technical, policy and market uncertainty. The real options theory (ROT) provides a method to account for these uncertainties and introduce flexibility in the investment decision by allowing decisions to be changed in response to the evolution of uncertainties. ROT is already being applied frequently in the evaluation of renewable energy or carbon capture and storage (CCS) projects, e.g., addressing the uncertainty in the price of CO₂. However, ROT has only found a few applications in the CCU literature to date. Therefore, this paper investigates the specific types of uncertainty that arise with the utilization of CO₂, identifies the types of real options present in CCU projects and discusses the applied valuation techniques. Research gaps are identified in the CCU literature and recommendations are made to fill these gaps. The investment decision sequence for CCU projects is shown, together with the uncertainties and flexibility options in the CCU projects. This review can support the real options-based evaluations of the investment decisions in CCU projects to allow for flexibility and uncertainty.

Megaprojects are complex and contain multiple risks and uncertainties. The dominant ‘predict and control’ planning method mainly ignores risks and uncertainties, making megaprojects inflexible and vulnerable to unforeseen changes. Insights and methods from real options theory (ROT) in economics and finance have the potential to improve planning of megaprojects in three ways: (a) better management and assessment of risks and uncertainties, (b) a more transparent and explicit identification and communication of risks and uncertainties, and (c) a monetary valuation of flexibility. An in-depth literature review of 42 papers of real options applications to megaprojects serves as a benchmark to analyse if current real options literature meets these three expectations. Through this review, we identify the main trends, relevance and research gaps. While its theoretical relevance is illustrated, three main gaps impede real options’ practical relevance for megaprojects: the applications paint an incomplete picture of megaprojects; its mathematical complexity; and the lack of empirical evidence of real-life cases. Based on a plea for more interactive research between scholars and planning practitioners, we provide an agenda for further research as to how ROT can better meet its expectations and fulfill its potential for the planning of megaprojects.
