COVID-19 has significantly affected the financial and commodity markets. The purpose of this investigation is to understand the impact of the COVID-19 crisis on Dow Jones and West Texas Intermediate (WTI) oil returns in relation to other crises using the Exponential Generalized Autoregressive Conditional Heteroskedasticity (EGARCH) model. The results indicate that COVID-19 and the accompanying lockdown have adversely impacted both yields and that the impact on oil prices is more significant than on the Dow Jones index. The variance and squared residuals of oil prices and the Dow Jones reached their highest historical levels during the COVID-19 outbreak, even higher than during the global financial crisis, and especially the VaR of both markets reached their historical peak points during the COVID-19 era. The variance of WTI during COVID-19 is higher than that of DJI, as was also the case during the financial crisis. These findings confirm that COVID-19 has negatively impacted investors’ ability to determine optimal portfolios and thus the sustainability of financial and energy markets more than the global financial crisis of 2007–2009. We, therefore, suggest that policy changes are needed to maintain financial sustainability and help investors deal with future financial and other crises.

Construction is one of the most energy-intensive sectors in the world. To scale down the energy demand of the building sector, some changes must be made. Formal exemplifications of this need can be seen in recent changes in the law in different countries. The energy identity/performance certificate contains requirements about buildings’ energy consumption in Turkey, and the Energy Performance Regulation in Buildings is mandatory from 01.01.2020. Moreover, it aimed to measure the level of awareness of individuals in saving energy. Face-to-face surveys were conducted with the use of a questionnaire with individuals residing in Adana's pilot region on the awareness of similar issues such as green buildings and energy efficiency, especially energy identity/performance certificate. The survey results were prepared in Microsoft Excel, and the reliability of the survey questions was measured with the help of the SPSS (Statistical Package for the Social Sciences) program. The analysis of the data was obtained from WEKA (Waikato Environment for Knowledge Analysis). Association rule extraction, which is one of the data mining methods, was used in the analysis. Based on the findings, it was seen that most of the individuals did not have enough information about the topics in the survey.

This paper examines the effect of energy consumption, globalization, and economic growth on the CO2 emission of the BRICS (Brazil, Russian Federation, India, China and South Africa) region. Using annual data from 1989 to 2019, this research applies a panel cointegration approach. In this framework, we use Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS) methods to examine the long-run relationship between the selected variables. This empirical investigation reveals that there is a long-run association between these variables, and energy consumption positively and significantly affects the carbon emission in these countries. These results indicate that energy consumption is the primary source of environmental degradation in the region. In contrast, the globalization (KOF Index of Globalization) negatively and significantly affects the carbon emission, implying the improvement of environmental quality. Further, this research could not find the presence of environmental Kuznets curve in the region. Policy guidelines are suggested in the line of findings.

Due to the negative impact of Heavy Pollution Projects (HPPs) on the surrounding environment and the general public’s daily life, HPPs are often resisted by the public during the site selection process, resulting in “Not in My Back Yard (NIMBY)” events, which hinder the implementation of the project. Demonstrating an early warning system is important to determine the NIMBY likeliness of HPPs. However, the existing literature related to the NIMBY assessment has deficiencies in terms of the assessment subject, method, and procedure. The aim of the study was to establish an early warning system to determine NIMBY level of HPPs in China. The early warning system was constructed based on the ordered weighted averaging operator and cloud model from the perspective of public perception. The results showed that the NIMBY level of the case project was “Center”, and the indicators with “High” level included the public security influence, the impact of production safety accidents, the impact of wastewater pollution, and the impact of toxic gas pollution. Finally, by analyzing the NIMBY issues for the project, we propose suggestions for the prevention and treatment of social security issues, production safety accidents, and wastewater and toxic gas pollution. To reduce the NIMBY level and ensure the smooth implementation of the project, the environmental protection department of the government should strengthen its environmental protection supervision, and the enterprise should strengthen the social safety management of workers, establish a perfect production management system, and upgrade and improve the treatment facilities of wastewater and toxic gas.

Until now, construction was considered through the prism of technical possibilities of implementing investment plan supporting and, at the same time, urbanization processes. The development model, present in highly developed countries, is far from sustainable. The departure from natural technologies for erecting construction works must have resulted in excessive use of resources, mainly nonrenewable. The strong negative impact on the natural environment of the architecture, engineering, and construction (AEC) industry cannot go unnoticed. Therefore, a solution to the problem of excessive energy consumption in technological processes in construction, which are also generators of huge amounts of pollution, should be discovered. Circular economy (CE) is one of the concepts of response to the threat posed by these negative externalities. It is worth considering construction materials as reusable elements, e.g., after the demolition of a building. The implementation of the CE concept in AEC requires an identification of the next stage in the life cycle of buildings—the rebirth. The chapter focuses on the issues of green public procurement present in the orbit of interest of decision-makers from the European Union. It was associated with the idea of CE, which is significantly entering the construction sector in both managerial and technical terms.

Society and the business world are paying more and more attention to the Circular Economy (CE) principles. The construction industry is no stranger to this issue, and the companies are transitioning towards sustainable production models. However, it is not easy to predict when and to what extent a company implements the CE. To measure this process, a scorecard, that includes the main Key Performance Indicators (KPIs) of the construction industry, related to the CE, was designed. Thus, the objective of this article is to design and test the CE-dashboard applicable to the construction industry. To do it, firstly, a literature review is performed. The next step is the selection of the KPIs collected in the literature, more suitable for reporting information about CE. Afterwards, a simulation based on the Monte Carlo technique performs. After multiple iterations, this method establishes the most probable KPI values as a result, which will be confronted with the limits used in the scorecard. With all this information, the dashboard emerges in Qlik software. Finally, a test of this dashboard takes place according to the information about KPIs from one of the leading Spanish companies (General Contractor (GC) building company). This step brings the validity of the created measurement instrument.

More and more construction projects are closed before they ever start. Among the most significant reasons for project failures is cost risk. Construction companies have many problems with reliable cost management. Rising demands of the key market players insist on making construction projects more sustainable according to the simultaneous improvement of the economic, environmental and social responsiveness dimensions. In order to investigate these problems, a four-phase research methodology has been followed consisting of: (1) literature review to identify research trends and gaps, (2) survey to construction experts to detect their subjective perspectives about risk costs and analyse the corresponding costs structure for the investment in sustainable projects, (3) simulations based on Monte Carlo simulation with an author’s methodology for calculating the cost risk with an additional statistical analysis, (4) ending questionnaire to obtain the final feedback from the experts and the validation of obtained results. A contribution to the development of knowledge about cost risk is the observation that the changing probability distributions of individual cost-generating components may include both economic as well as technological and organizational aspects. Thus, with the proposed approach, often complex, global challenges of sustainable construction projects can be tackled in an accessible way.

Circular economy (CE) is an emerging economic model based on the endless circulation flow of resources creating additional value. In temporary organizations such as construction projects, all administrative decisions are crucial for final success. One of the ideas is to enroll a circular economy manager (CEMR) and put him in an organizational structure. Implementation of the CE concept should be the effort of the entire project team. However, actions specific to the innovative nature of the procedures related to the CE in construction projects require additional support. It can be provided by professionals who can adapt a wide spectrum of knowledge to be used for promoting CE in the execution of construction processes. CEMRs can play the role of patrons of the CE issues because they support project managers in saving material resources in construction projects. The symmetry between visible outcomes of the CE idea and the employment of an extra manager has contributed to the development of the CEMR selection criteria model. However, effective recruitment for such a post may be a bit complicated for decision-makers, especially when CE is still enigmatic, as its procedures are quite undiscovered. All in all, the multi-criteria decision-making problem forces one to prepare the list of selection criteria and to rank them according to status in the hierarchy. This article shows prioritized criteria for selecting the CEMR based on the advanced literature review concluded after several expert-based reviews and calculated after some Monte Carlo simulations. The main purpose of this article is to help decision-makers in construction projects to perform a reliable recruitment process.

The principal production activity of construction companies is centralised on the investment and construction projects executed on various construction sites. In the pursuit of using the potential accumulated in the means of production, construction companies start to manage a number of projects implemented concurrently. Therefore, a project portfolio is a key challenge for the strategic management of modern construction companies. There is a way to deal with the multi-project phenomenon called the project portfolio management. At this level, specific features of construction production have to be taken into account. An efficient selection of the project portfolio, treated as the project portfolio management maturity, allows reducing the risk associated with investing in projects, by creating a combination of expenses on a number of projects. The strategies accepted by an organisation determine the project portfolio to the implementation according to some specific requirements (scope, deadlines, cost, quality). Disruptions of meeting these requirements generate the risk associated with concrete projects, and the configuration of the project portfolio, i.e. a number of projects implemented parallelly, their distribution in time and space, produces the risk connected with resources vital to the project execution. Results of a survey conducted among 100 Polish construction entrepreneurs, regarding the problems of establishing the project portfolio management, were presented. Majority of respondents indicated a profit margin as the most important factor in the selection of the project. A number of projects executed in one year, in individual groups of the surveyed enterprises, varies. Large companies usually execute up to 5 projects at the same time. In turn, small and micro-sized enterprises are mostly involved in 6-20 projects in one year. The research revealed that the most frequently indicated criterion for selecting the project portfolio in the construction industry is the availability of workforce. Subsequently, the availability of materials and equipment were indicated in the second and third place. All factors of production, i.e. human resources, materials, equipment as well as financial resources, become sources of the risk in projects, as it comes to a chance to obtain or substitute them. The summary includes a conclusion of the considerations, containing a specification of criteria for selecting the project portfolio in a construction company.

A construction project shapes the natural environment of human beings throughout its life cycle. Therefore, problems related to the ecological quality of the applied solutions require special interest. A method of solving these problems can be directly related to stakeholders involved in the projects. The role of a construction company in the context of decision making problems, and in particular its ecological responsibility, has become one of the fundamental elements of the genesis of this research. Linking ecological maturity of the stakeholders participating in the implementation of construction projects, and taking into account the environment friendly approach, related to the scarce resource management and the possibility of reducing their environmental impact, became the main goal of the article. The detailed objectives of the conducted research can be connected with promoting eco-friendly strategies among construction companies and increasing the awareness of construction entrepreneurs about the current EU requirements regarding the environmental issues of business. There is also a need for building ecological maturity of construction companies. Research conducted among the management staff of construction companies allowed to specify some factors of the ecological maturity in construction enterprise (EMCE) and their priorities.

The article describes the roles of particular subjects involved in a construction project, taking into account risk factors related to decision making process. It was revealed that the construction process is located in the area of investment and construction projects, and therefore the risk factors of the construction project should be expected around the projects. Case studies (own research of authors – direct interviews) involving the risk problems of stakeholders involved in an-execution of the construction projects were presented. The risks and their mutual relationships were also described.

An idea of sustainable development is spread in many aspects of human activity. Recently, there has been a growing interest in it among entrepreneurs of various industries. Investigations of researchers in the field of ecology issues led to a formulation of the Ecodesign Maturity Model (EcoM2) supporting production companies in their pursuit of providing more sustainable products and services. The Circular Economy (CE), on the other hand, appears as a concept of reducing the ecological footprint by finding new concepts of the flow of matter in manufacturing processes, assuming its closed loop. In the literature, comparisons of production systems compatible with the idea of CE to ecosystems occurring in the natural environment, also known as closed ecological systems, can be found. CE in a building sector may be considered at different levels. At first, we can treat objects as ones that can be reused as a whole without any extra processing, for example: construction elements, pallets and multi-use wrapping of building materials. The second level includes reused parts of the construction that need to be remanufactured. The last stage requires a process of recycling, e.g. after a demolition of buildings, building materials are shredded and reprocessed into new elements. The EcoM2 model is used as a basis for an implementation of the Circular Economy in the construction industry. It is justified by its specificity because the construction of buildings is always associated with interference in the natural environment. The aim of the article is to indicate the role of construction enterprises in implementing the CE concept in the sector at the level of both processes and products, treated as an outcome of their activity. The article refers to the functioning of construction companies, including CE in their business strategy. The CE problem in a construction company should be recognised within the entire organizational structure. The concept of Circular Economy Maturity (CEM) of the enterprise is defined. The assumptions of the CEM model for construction enterprises is also described. The basic features that should characterise a company that is mature in terms of the application of the CE concept are specified. It is worth to note that the CE maturity is represented by enterprises that have a natural ability to reform and improve an ecological quality of their products and services. Moreover, these organizations are able to have unified processes and procedures that are identified, and knowledge about ecology is effectively communicated to employees. All organizations that have a CE maturity should plan all activities using processes that are designed and then improved by follow-up studies.

One pillar of the European Union's policy is the environmental policy, which indicates, among other things, a need for taking into account ecological conditions and effects in all types of economic activity. The construction industry is exposed to conflicts between processes and the natural environment. Taking into account the sustainable development in construction projects requires an inclusion of environmental problems in the scope of project risk management. Risk management in construction projects is considered as a very important process supporting the achievement of project goals in terms of time, cost, quality, safety and stainability issues. The aim of the article is to pay particular attention to the latter aspect. Project risk management is effective when it is implemented in a systematic manner throughout the life cycle of the construction project. The article indicates that the specific features of construction activity have a significant impact on shaping the nature of construction investment projects. Their executions are connected with deep and long-lasting interference in the natural environment, and they are burdensome for the environment, both in the construction phase, as well as during their maintenance and liquidation phase. It requires the consumption of significant amount of material resources and the involvement of a number of specialists and institutions making decisions in succeeding phases of the life cycle of erected structures. Therefore, these projects have many stakeholders - interested, to a different extent, in the particular stages of the project. The results of the survey carried out among construction entrepreneurs at the turn of 2015-2016 about the fuel and energy consumption in the logistics processes of construction projects are presented. This provides a basis for answering a research question about how seriously entrepreneurs treat sustainability problems. Risks related to sustainable development are indicated on the map of risks in the construction project. It is emphasized that construction works should be executed with the use of such energy-saving technical solutions that enable for minimising a use of natural resources in the construction and maintenance phases, and in the final stage will allow easy liquidation of the structure.

The growing demand for electricity forces the humanity to find the most economical methods of its production. Functioning without electricity in today's world deprives human from the possibility of a free existence, and even completely prevents it because of the technicisation of society. Growing awareness of acquiring "clean" environmentally-friendly energy from renewable sources contributes to the successive development of this sector of the economy. The purpose of the article was to analyse the risk of construction costs for small hydroelectric power plants along with an indication of the location and needs of a small hydroelectric power plant in Poland. The subject of the study was a small hydroelectric power plant producing electricity, using a turbine to convert the kinetic energy of water into mechanical energy. Aiming at illustrating the benefits of the discussed investment based on the estimation of construction costs and, as a result, financial results, a specific case of a small hydroelectric power plant located in the region of Kujawsko-Pomorskie [Kuyavian-Pomeranian Viovodeship] in central Poland was analysed. The intended research objective was achieved using industry literature, magazines as well as technical knowledge of persons holding building qualifications (including hydro-technical construction) and materials made available by two Bydgoszcz companies specializing in the implementation of small hydroelectric power plants. The COMAR- Jarek Górecki® algorithm, which operates in the industry as the author's concept of calculating the variation of financial outlays incurred for the implementation of investment and construction projects, was used to analyse the risk of costs of a construction project.

Risk management plays a key role in project management methodology. Nowadays, it is quite common to manage projects with the use of digitally collected data. The Big Data (BD) analysis can enhance the quality of information taken from these records and be used for project management. Moreover, it can be a project risk management tool. Some examples of BD application can be found in the investment and construction projects which use both physical and virtual data derived from controlling, bids for tender, schedules from sub-contractors or some other specific information. An accurate analysis of all that data (BD) makes it possible to discover new phenomena characteristic for the project. Getting to know them can be helpful in reducing the risk of accomplishing the project objective. The chapter is intended to arouse the readers’ interest in this new source of valuable information, required to improve a course of projects. An awareness of utility of Big Data was presented on the basis of the recent anonymous survey among Polish construction entrepreneurs at the turn of years 2016 and 2017. The research has been the first step towards the broad analysis of the propensity of construction companies for using BD in project risk management. Moreover, it points out some capabilities in this matter.

The article indicates that a role and tasks of particular participants of construction projects vary depending on the phase of construction production. The influence of individual entities on the quality of construction production is also diversified. The results of the questionnaire survey conducted among 64 employees of construction companies involved in the implementation of construction projects were presented. They show the opinions of respondents representing the construction industry about a role of participants of the construction process in maintaining the proper quality of construction works. Their impact on the compliance of construction processes with applicable legal regulations was emphasized. The declarations may cover PN/EN standards, Polish construction law, technical specification of performance and acceptance of construction works and other formal and legal requirements and construction production standards.

The construction industry is among the sectors that need closer attention due to their environmental impact. The Circular Economy (CE) model promotes the transition to more sustainable production models, which are based on careful management of resources and the reduction of negative externalities generated by such businesses. Its application in this industry can foster significant improvements in sustainability. However, the measurement of the degree of implementation of CE is difficult, owing to an absence of psychometrically sound measures. In this paper, the development of the CE scale for the building industry was described, treated as an instrument that allows for a direct measurement of the importance of CE for companies. The processes used to generate items by applying the e-Delphi research technique were explained in the article, and the developed scale was tested and validated through confirmatory factor analysis (CFA). The final construction is composed of seven different weighted dimensions: four related to Resource Management: 3Rs (Reduce, Reuse, and Recycle), Efficient Management of Energy, Water, and Materials; two dimensions regarding environmental impact: Emissions and Wastes generated; and, one providing indicators of transition to the CE.

Risk management requires a comprehensive review of possible hazards, their possible outcomes as well as some recommendations about minimizing the risk. The study emphasises that the project risk management refers to an analysis of the risk factors and a creation of the strategy minimising negative effects of the risk. It was pointed out that a construction project is this kind of projects that can be defined as a unique process of high complexity (design documentation, various stages of creating the building), which has clearly defined time frames and a given financial limit. It is executed as a team work, by qualified or highly qualified specialists of different matters, for example masonry, precast, etc. Additionally, it requires a use of modern equipment and an adequate preparation of the investment. Therefore, the risk management focuses on the problems allowing for troubleshooting. A basis of the risk management is to recognise the fundamentals, which are crucial for the construction project management, i.e. an object perspective, including technological, supporting and management processes as well as an entity perspective – project stakeholders. Construction projects require also an acquaintance with the specificity of the branch. The article refers to the risk management in construction project and, in particular, a phenomenon of participants' fairness in such projects. The problem of fairness of the entities involved in a project should be understood as a fair play, according to the arrangements agreed in a contract and compatible with current formal procedures and social rules. It was indicated that fairness can be treated as an important factor in predicting the success of such projects. Interviews conducted among contractors in Kuyavian-Pomeranian region showed varied fairness requirements put to individual participants of construction projects. The article presents results of the research. It shows a desired attitude of the surveyed enterprises towards a problem of the fair behaviour. These behaviours, relating to individual stakeholders, have been underlined in different phases of the construction projects' life cycle.

The article presents an entity perspective of the construction investment projects. In a course of the project there are stakeholders who have an indirect influence (e.g. decision-makers in the selection of projects) or a direct influence (e.g. members of the project team). An intuitive opinion about a significant influence of project stakeholders on the project's course encouraged the authors to undertake a research in this area. The article illustrates the initial phases of the construction project life cycle in a perspective of the entities and, in particular, a role of different stakeholders in making decisions that affect a course of the project. An analysis of the structure of the construction project life cycle makes a substantial involvement of various subjects in the initial phases of the project, i.e. in an initial phase and during a creation of the structures. A key point is to underline the factors of decision-making by the participants of the construction process. It was indicated that the stakeholders have a different impact on the course of the project. In large projects, which have many stakeholders, their role in the implementation of the investment project can vary, depending on the life cycle of the project. They can have positive or negative impacts on achieving the project objectives. The paper presents the results of 100 surveys made among participants of the building processes, executors of the construction projects in the Kuyavian-Pomeranian region. The study was conducted in December 2016 and January 2017. It revealed what is the impact of individual stakeholders of the construction projects on the course of the project. A special attention was paid to a complex relationship between objectives of the project and stakeholders' goals. A great care to the smallest possible number of risks, which may arise from the different objectives of the project and its stakeholders' goals, should be focused on the augmentation of correlation of measures of the goals. It is crucial to identify the stakeholders, whereas it is a continuous and quite difficult process. However, when ignoring the impact of specific stakeholders on the implementation of the project, a duration of the project and its costs may increase. A main problem, in establishing a relationship of participants in the construction process, is to take into account the risk of all project stakeholders.
