Abstract
Purpose
This study aims to assess the awareness and knowledge level of procurement officers (POs) in Ghanaian tertiary educational institutions regarding sustainability in general and specifically on environmental sustainability in the Public Procurement Act 2003 (Act 663) as amended.
Design/methodology/approach
Through purposive sampling technique and face-to-face interviews using semi-structured open-ended questions, qualitative data was collected from 19 POs who are well vested in the procurement profession and willingly agreed to partake in the research. The qualitative data were analyzed using content analysis technique to help organize and elicit meaning from the data collected and to draw realistic conclusions from it.
Findings
The results showed that most POs were aware of the Public Procurement Act 2003 (Act 663) as amended, primarily through seminars and workshops organized by the Public Procurement Authority. The interviewees demonstrated a good understanding of sustainable procurement, considering its social, environmental and economic aspects. However, one respondent primarily associated sustainability with only environmental issues. The POs were, however, of the view that the Amended Act 914 (2016) does not give detailed highlights on environmental sustainability, making implementation very difficult, especially regarding the procurement of goods. Overall, the findings indicate a positive level of environmental sustainability awareness and knowledge among the interviewed POs regarding the Public Procurement Act 2003 (Act 663) as amended.
Social implications
The findings from the study could be used by policymakers to strategize educational campaigns by using the POs’ knowledge and awareness to the implementers of Act 663 (2003) as amended to effectively ensure environmental sustainability in procurement practices. The findings from the study have also contributed to the literature on procurement policy by drawing the attention of policy formulators to give equal attention to all the sustainability pillars, i.e. social, economic and environmental. This would consequently help the implementers to contribute to achieving sustainable development.
Originality/value
This study is one of the few empirical qualitative types of research seeking the views of POs in tertiary educational institutions in Ghana on sustainability and environmental sustainability as enshrined in the Public Procurement Act 2003 (Act 663) as amended. The findings give positive feedback to policymakers on the knowledge and awareness level of the POs on environmental sustainability and highlight the importance of awareness programmes and educational initiatives by the Public Procurement Authority and other stakeholders to ensure compliance with the Act.

Abstract
Purpose
This study aims to identify in literature the role of construction stakeholders in the implementation of circular economy (CE) in the construction industry (CI). This study also sought to identify the status quo and research trend, “hot themes”, areas requiring more research and future research direction of stakeholders’ role in CE implementation in the CI.
Design/methodology/approach
A literature search was conducted using the Scopus search engine, augmented by Google Scholar to produce 50 relevant articles for the identification of stakeholders’ roles using content analysis. The scientometric study was undertaken using VOSviewer on 42 articles obtained from Scopus search to identify the status quo, “hot themes”, knowledge gaps and future research direction of the role of stakeholders in CE implementation.
Findings
Through content analysis, the identified roles of government as a stakeholder are to develop efficient policy instruments, legislation support and financial investment in research and development activities that will promote the smooth implementation of CE. The role of academia/research is to engage in research aimed at investigating both the short-term behaviour and the durability of recycled materials and products. In addition, the roles of professionals in the consultant/design/procurement team are to design with life cycle assessment and reused materials, design for deconstruction and disassembly, etc. The role of the user/consumer is to ensure knowledge diffusion and awareness exchange that recognize the available opportunities for long-term material usage (including repair, reuse, refurbishment and recycling). The research status quo identified from the scientometric analysis include how stakeholders can come up with innovative ways in demolition that will ensure that more of the materials can be reused. Stakeholders should focus on enacting policies and laws that can promote the use of recycled materials in buildings, etc. Research that focuses on how to engage the various construction stakeholders to come up with specific public policy that will promote CE implementation, identifying the specific roles to be played by stakeholders during policy enactment as well as managing the environment, laws and legislations towards CE implementation. The role of stakeholders in the extension of the life span of projects, the use of strategies to minimize waste generation and standardization of building materials, components and connectors with the purpose of simplifying disassembly are the research gaps and areas for future research studies. Some of the research “hot themes” include “circular business models in the CI”, “environmental sustainability policy implementation”, “environmental, economic and social sustainability”, “policy, laws and legislations on waste management” and “environmental and industrial economics” towards CE implementation.
Practical implications
The findings from this study serve as a valuable reference for construction stakeholders to assess their specific roles as stakeholders and to identify the status quo and research trend, “hot themes”, areas requiring more research and future research directions on stakeholders’ roles in CE implementation in the CI.
Originality/value
Identifying the role of stakeholders for CE implementation is one bold step towards the achievement of CE implementation in the CI.

Abstract
Purpose
There is sufficient literature on green knowledge regarding supplier selections. Notwithstanding, there are hardly any empirical studies that analyze green knowledge toward supplier selection through the lenses of green intellectual capital (GIC). This paper aims to analyze green knowledge development toward supplier selection through the lenses of GIC.
Design/methodology/approach
This study uses an exploratory case study approach involving seven public universities in Ghana. A purposive sampling technique was used in selecting respondents who were interviewed through face-to-face and focus group discussions with a semistructured interview guide. Atlas ti software was used to generate themes for discussion.
Findings
The findings of this study attribute the nonapplication of green criteria to supplier selection to low knowledge among practitioners. Training, collaboration, opportunities for further studies and affiliation with professional bodies were identified as means to enhance green knowledge. Green human capital factors that support knowledge enhancement include commitment, capability, skills and ease of understanding.
Practical implications
Green procurement practitioners in public universities in developing countries stand little chance of integrating green criteria into supplier selection if they do not develop their level of knowledge.
Social implications
Selecting green suppliers is a complex issue for public organizations, particularly universities. This study would therefore help equip managers of public universities and procurement practitioners with the relevant GIC knowledge for the successful integration of green credentials into supplier selection.
Originality/value
This paper highlights the importance of knowledge in green supplier selection. To the best of the authors’ knowledge, analyzing the role of GIC in knowledge development is considered the first of this kind of study.

Abstract
Purpose
The purpose of this study is to identify the capacity needs of building professionals to deliver environmentally sustainable buildings (ESBs) globally, from a unique systems approach. Through a review of extant literature, this study contributes to knowledge of the global delivery of ESBs by identifying research trends and gaps that can be tackled in future research, and current hotspots in capacity building (CB) research within the built environment (BE). The adopted systems approach to CB postulates that the construction industry is systemized in nature, and thus, CB solutions within the industry should be approached from a systems approach.
Design/methodology/approach
A literature search was conducted using the Scopus search engine, augmented by Google Scholar and Web of Science, to produce 54 relevant articles for analysis. The scientometric analysis was undertaken with the use of VOSViewer to better understand the broad literature on CB in the construction industry which would not have been possible with traditional data analysis. The content analysis allowed, for a systematic review of selected articles, to reveal key themes in this study.
Findings
Through a content analysis, four levels of CB were identified within the construction industry; individual level, organizational level, industry level and state level. Nine sub-capacities were subsumed under the four identified levels adopted from Potter and Brough (2004), including but not limited to Performance capacity, Workload capacity, Supervisory capacity, Industry Role capacity and Systems capacity. Under each sub-capacity, key questions were posed to aid identify the capacity needs of BE professionals. A framework for identifying capacity needs in the BE is proposed.
Practical implications
The findings of this study serve as a useful reference for practitioners and policymakers to assess their level of commitment to CB efforts for ESB delivery. The findings of this study have revealed that building the capacities of BE professionals to deliver ESBs should be addressed as part of a broader framework, interdependent on the other levels of CB in the systemic construction industry.
Originality/value
As a review study identifying capacity needs for BE professionals to deliver ESBs, this study enhances knowledge of CB within the construction industry.

Abstract
Purpose
Employee unsafe behaviours and failure to adhere to safety standards resulting from poor safety perception among employees contribute to the high rate of accidents in the construction industry. This study seeks to examine the role of respectable engagement in improving construction workers' safety perceptions in the Ghanaian Construction Industry.
Design/methodology/approach
The study adopted a quantitative research method where survey questionnaires were administered to respondents. Sixty-six construction workers who were actively involved in ongoing construction projects in Kumasi and Greater Accra regions of Ghana were selected through stratified purposive sampling. The analytical tools utilised in the data analysis include a one-sample t-test, descriptive statistics and mean score ranking.
Findings
The study identified five key drivers and strategies of respectable engagement from pertinent literature. The findings confirmed that all these drivers and strategies play a key role in improving workers' safety perception. The study further revealed that improving employees' safety perception will enhance and sustain their awareness of the organisation's commitment to health and safety. Employees will therefore portray positive safety behaviour by adhering to the safety standards of their organisation.
Practical implications
The findings of this study will contribute to construction site safety improvement by informing contractors, site supervisors and other stakeholders of their role and the need to improve their worker's safety perception.
Originality/value
This research is unique in that; it identifies the role of respectable engagement in improving construction workers' safety perception. This research creates awareness among management and site supervisors on the need to be present for their workers, affirm them, attend to their needs, understand and appreciate them, and communicate and listen to them.

Abstract
Purpose
This research presents a comprehensive review of the literature on the barriers to incorporating indoor environmental quality (IEQ) principles into building designs. The aim was to identify these barriers in the literature and subsume them under broad categories for the development of a framework showing the interrelationships among the barriers.
Design/methodology/approach
The research design used a systematic desktop review which comprised of three levels of screening. The first level allowed for a broad selection of papers; the second level of screening was done to limit the results to papers within the construction industry, and the third level of screening limited the documents strictly to the publication period of 2000–2021.
Findings
Twenty-four (24) barriers were identified in the literature, including lack of integrated design teams, which ranked the highest in appearance, high initial costs, poor market for IEQ buildings and higher design charges among others. The identified barriers were classified into six (6) categories namely capacity barriers, economic barriers, process-related barriers, cultural barriers, client-related barriers and steering barriers.
Practical implications
The findings of this study would enable practitioners and policymakers to better understand what is preventing the widespread adoption of IEQ designs in the built environment and devise actionable strategies to overcome them. It adds to the body of knowledge on IEQ research by categorizing the various barriers that prevent the delivery of IEQ projects.
Social implications
The developed barriers in this research can serve as a useful checklist to future researchers who may want to validate the barriers to IEQ designs in empirical studies and in different settings.
Originality/value
The interconnectivity revealed by the web-like framework allows for an appreciation of the various barriers of IEQ adoption which would help in expanding the current knowledge on IEQ beyond the narrow scope of isolated barriers. The fact that the papers selected in this study are not limited geographically, underscores the wide applicability of the findings in the global construction industry.

Abstract
Purpose
The aim of this study was to identify these enablers in literature and subsume them under broad categories for the development of a framework showing the interrelationships among the enablers.
Design/methodology/approach
Fifty-four (54) relevant articles were desk reviewed from different construction peer-reviewed journals and published conference proceedings to identify 20 core enablers of incorporating indoor environmental quality (IEQ) into building designs.
Findings
The identified enablers include improved occupants' health, well-being and satisfaction, environmental conservation, high return on investments and co-operative methods of design and construction management among others. To better understand the enablers identified, they were classified into seven main interconnected categories: economic enablers, environmental enablers, occupant and end-user enablers, process enablers, corporate image, culture and vision enablers, client-related enablers and external enablers.
Research limitations/implications
The interconnectedness brought to the fore a subtler appreciation of the drivers of IEQ, which could help expand current knowledge outside the narrow scope of isolated drivers. The fact that the papers selected in this study are not limited geographically underscores the wide applicability of the findings to the global construction industry.
Practical implications
Understanding that the enablers will enhance the adoption and design of quality indoor environments, help in building the capacity of consultants to adopt the design of quality IEs and reduce the impact of construction on the environment.
Social implications
These identified enablers are not limited geographically and thus could promote the design of quality indoor environments globally, particularly in green building design. To the global construction community, this review presents a list of enablers that would expedite the adoption of principles of IEQ designs in buildings thus taking the global construction industry one more step towards sustainable built forms. Promoting the identified enablers would ultimately steer stakeholders to design and build better indoor environments.
Originality/value
The fact that the papers selected in this study are not limited geographically underscores the wide applicability of the findings to the global construction industry.

Abstract
Purpose
The purpose of the study is to investigate the challenges in improving women's energy access, rights and equitable sustainable development from a Ghanaian perspective.
Design/methodology/approach
The research utilizes a mixed method. A qualitative in-depth exploratory design was chosen to understand how gender is mainstreamed within Ghana's energy sector. This included semi-structured interviews with key managers, experience policy experts and focus groups. The semi-structured interviews were analyzed using thematic content analysis (TCA).
Findings
The study reveals that the National Energy Policy of 2010, as the main energy policy regulating the energy sector in Ghana, does make provision for gender equality, safety especially women, in line with Ghana's sustainable development goals. The energy policy aims to empower women and create gender parity in the sector. Nevertheless, the study also found major challenges to gender mainstreaming in the energy sector, including poor analysis in formulating energy policies, inadequate financial resources, and poor monitoring and evaluation.
Originality/value
The paper exposes gender equity challenges associated with the energy sector in Ghana. It also offers a new policy angle which connects gender mainstreaming to sustainable development. The research describes how women are included in developing energy policies and in addressing gender challenges in the energy sector.

Abstract
Purpose
This study aimed to identify barriers impeding circular economy (CE) uptake in the construction industry in literature, categorize them for the development of a framework and to seek the interrelationships among the categorized barriers. This allowed for identifying integrated solutions to holistically address the barriers. The study also sought to identify the “hot” themes, the knowledge gaps and future research directions on barriers impeding CE.
Design/methodology/approach
Forty-eight relevant articles were desk reviewed from different construction peer-reviewed journals and published conference papers. A scientometric analysis allowed for co-occurrence of keywords relating to CE. A content analysis enabled the identification of 79 barriers impeding the uptake of CE in the construction industry which were further categorized into six distinct categories for the development of a framework showing the interrelationships among the categorized barriers.
Findings
The identified barriers include construction sector inertia, lack of design standards, lack of knowledge, awareness and understanding, design cost, and perception of second-hand materials as substandard among others. The study categorized the identified barriers for better understanding into six different groups: cultural barriers, social barriers, environmental barriers, economic barriers, technical barriers and technological barriers. Strategies to address the barriers were also proposed. The interrelationships among the various barriers were also shown in a proposed framework to educate professionals on the interconnectivity of the barriers.
Practical implications
Categorization of the various barriers impeding CE uptake contributes to the body of knowledge. Also, the interrelationships among the various categorized barriers in the framework will enable construction professionals make informed decisions regarding the successful integration of CE in the industry, better appreciate the barriers that impede CE uptake and apply strategies to holistically address the barriers. This will expand current knowledge outside the narrow scope of isolated barriers.
Social implications
To the global construction industry, the review presents a list of barriers and their interrelationships that could provide implementation strategies for the uptake of CE in the industry.
Originality/value
The geographical scope of this study is not limited, and therefore encourages wide applicability of the findings to the global construction industry.

Abstract
Purpose
This paper aims to provide a systematic review of extant literature on supplier selection by identifying drivers of integration of Environmental Sustainability (ES) into supplier selection, with the aim of classifying them under broad categories for the development of a framework showing the interrelationships among them.
Design/methodology/approach
A search was ran for selected keyword themes using three powerful and rigorous search engines: Scopus, Google Scholar and Science Direct, to identify relevant articles from 12 peer-reviewed journals. These were desk reviewed through manual filtering to select drivers of integration of ES into supplier selection.
Findings
Thirty-one drivers identified from 41 relevant articles as propelling integration of ES into supplier selection were then classified into five categories: strong policy direction, high level of commitment, desire for high reputation, robust technology and availability of green products. This yielded a framework showing the interconnectedness among the drivers.
Research limitations/implications
The study contributes to the body of knowledge by developing a classification of drivers of integration of ES into supplier selection. The interconnectedness brought to the fore a more subtle appreciation of the drivers of green integration, which could help expand current knowledge outside the narrow scope of isolated drivers. This study provides detailed analyses of drivers of green integration into supplier selection.
Originality/value
This paper provides a comprehensive review of drivers of integrating green into supplier selection, which is lacking in the body of knowledge on ES.
