Given the complexity of green public procurement, decisions are likely to be driven by bounded rationality. However, we know little about what determines supplier selection criteria in any given situation. This study explores buyer behavior when considering environmental criteria. We first conducted interviews and identified 12 operational procedures used by buyers. We then developed a survey to explore the use of these procedures. Our quantitative analysis suggests that public buyers are motivated by their belief that they can make a difference. This is independent of buyers' experience or gender. However, their occupational position and the nature of a procurement seem to influence how buyers seek information about environmental criteria and which information source(s) they use. The data suggest that four specific decision-making heuristics are associated with the selected operational procedures.

The purpose of this study is to discuss policy review in the interest of sustainable innovations in Malaysia’s public procurement. This study also offers the overall relationship between existing policies related to sustainable innovations in public procurement and the coherences towards the four dimensions of sustainable innovations.

This study outlines the current policies in Malaysia which are related to sustainable innovation initiatives and explores the cohesiveness that appears disconnected and understood separately. Policy content analysis is conducted on the current policies related to sustainable innovations in the context of Malaysia’s public procurement.

This study observed that the current policies related to sustainable innovations in public procurement are actually interconnected with each other through a hierarchical framework. This study also demonstrates that the 12th Malaysia Plan has comprehensively encompassed every aspect of the environment, social, economic and innovation to contribute to one primary goal – green economic growth.

The proposed policy framework is expected to be beneficial for the administrator executive among the civil servant to connect the independent policies and, at the same time, contribute to the overall goal of green economic growth. Through a broad policy structure too, this study helps the industry player to recognize their potential in any area related to sustainable innovation.

The policy framework illustrated is new to the literature, especially in Malaysia’s context. The compilation of current policy grounded by the 12th Malaysia Plan has not been presented in any publications.

In many countries, public procurement of goods, services and works is required to serve wider social purposes apart from the needs of the user agencies (which may be referred to as social responsibility procurement). In recent years, reforms have been implemented in the countries of East Asia to promote social responsibility procurement. They have entailed four main types of social responsibility: (a) supporting small and medium enterprises; (b) creating opportunities for small or start up venture firms; (c) fostering environmental sustainability through green purchasing, and environmentally sustainable construction (in the case of public works); (d) promoting work safety in site management in public works. The paper will examine the reforms in the countries of the region under which various preferential arrangements have been implemented to meet these objectives. It will consider why the reforms were adopted and also the differences between the countries of the region in the priority given to each of the reforms.

It is unclear as to what extent sustainable procurement is being practised in Ireland and what barriers there are to implementing it in organisations. This study provides the first complete insight into the use of sustainable procurement in Irish commercial semi-state bodies. It explores the extent and type of use of sustainable procurement plus identifies and examines the challenges to its use. A deductive approach is utilised to determine the barriers. Eleven participants, nine from the commercial semistate bodies and two experts with knowledge of this subject, are interviewed using semi-structured questions. The research findings show that sustainable procurement is being practised in the majority of the commercial semi-state bodies. Definition of sustainable procurement, the absence of mandatory guidelines, cost, time and a dearth of sustainable procurement knowledge by suppliers are some of the main barriers put forward by participants.

Scholars and practitioners have come to understand the important role of local governments in the causes and effects of climate change. The literature has examined both the substantive and symbolic determinants of urban sustainability policies in addition to the implementation issues associated with those policies. At the heart of these policies is the idea that local governments have the desire and ability to engage in socially and environmentally responsible practices to mitigate climate change. While important, these studies are missing a key component in the investigation of local government involvement in sustainability policies: government purchasing power. This study examines the effect of administrative professionalism and interest group presence on the determinants of green procurement in the understudied context of counties in the United States.

This study aims to uncover the black box of the influence mechanism between external stakeholder drivers and green public procurement practice, and meanwhile to explore the moderating role of administrative level in this process. Green public procurement (GPP) has been widely implemented. Existing literature has found that external stakeholder drivers can affect public sectors' GPP practice, however, the definition of its connotation is still unclear, and how external stakeholders affect GPP practice has remained a black box.

After defining the major external stakeholders, this study develops a multiple mediation theoretical model using survey data from 142 Chinese local public sectors. It aims to uncover the black box of the influence mechanism between external stakeholder drivers and GPP practice and meanwhile explore the moderating effect of administrative levels in this process.

The results show that external stakeholder drivers have a positive relationship with GPP practices. The knowledge of GPP implementation policies and the knowledge of GPP benefits can both mediate this relationship. This study also finds that the administrative level of public sectors can positively moderate the mediating effect produced by the knowledge of GPP implementation policies and negatively moderate the mediation effect produced by the knowledge of GPP benefits.

Local governments need to better encourage public sectors to implement GPP. Managers of public sectors need to pay attention to organizational learning to acquire relevant knowledge on GPP.

This study makes a theoretical contribution to a better understanding of the influence mechanism for GPP practice. This study also provides comparisons of GPP implementation policies between China and European Union.

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.

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.

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.

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.

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.

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.

Government green procurement (GGP) is becoming a popular environmental policy instrument to spur the economy whilst protecting the environment. However, the implementation of GGP is impeded by various barriers. This paper aims to analyse the existing literature on barriers impeding GGP.

This systematic literature review was guided by the PRISMA Statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) review method. A total of 29 articles from the Scopus and Web of Science databases were selected for the review.

Five themes, i.e. finance, legal, people, knowledge and organisation, emerged from this review, which further produced 16 sub-themes. Lack of knowledge and awareness were the major barriers for GGP, while financial constraint was not the major barrier for GGP, as previously perceived. Barriers related to organisation were the most complex. Certain barriers were found more in developed or developing countries.

Only article journals with empirical data were selected. Review articles, book series, books, chapters in books and conference proceedings were excluded.

Public managers should place highest priority to enhance knowledge and awareness of procurers on GGP. Other important initiatives to be undertaken include emulating best practices, implementing change management and incentivising suppliers to tackle the prevalent barriers of GGP. Finally, with increasing evidences on barriers related to GGP, public managers should consider mapping and analysing specific barriers hindering GGP in their organisation/country.

A less challenging and efficient implementation of GGP contributes to a cleaner environment.

This article will be the first to systematically review the barriers of GGP.

Green Public Procurement (GPP) has recently gained attention in the academic and policy arenas since climate change has uncovered the need to be addressed by both private companies and public entities. Because of this growing interest this study aims to explore the most influential journals, publishers, categories, topics and therecent trends and future research lines in GPP.

Based on the Web of Science database, 1,008 articles from 1990 to November 2023 devoted to GPP are analysed by using Bibliometrix, an R-tool to perform bibliometric analysis.

This study introduces the following findings. The most influential journals by far are Journal of Cleaner Production and Sustainability, differing in that the latter is open access (OA) while the former publishes through traditional subscription (TS). This result also occurs regarding the main publishers (Elsevier and MDPI).

GPP is a political commitment that contributes to improving the efficiency of the economies and that has aroused the interest of the scientific community. The paper can provide important insights for GPPs formulation in the areas of procurements and literacy.

The paper leads a debate on the opportunities or threats that the OA journals present for the dissemination of scientific knowledge of GPP, compared to TS publications in the same field.

This paper examines the role of government procurement as a social policy mechanism within a multilateral open trading system. Government regulations globally are being transformed to foster more responsible business conduct in multinational enterprises (MNEs). Yet, concern that sustainability may present a discriminatory barrier to trade has stalled the progress of sustainable public procurement (SPP) at the international level, raising questions regarding the role and scope of the World Trade Organisation’s (WTO) Government Procurement Agreement (GPA) to align taxpayer-funded contracts with the United Nations (UN) Sustainable Development Goals.

With a focus on social sustainability, this paper reviews the grey and academic literature to assess the changing landscape of public procurement policy and supply chain legislation in high-income countries.

Frontrunner nations are adopting a mandatory approach to sustainable public procurement and due diligence legislation is elevating supply chain risk from reputational damage to legal liability. While technological innovation and the clean, green production of manufactured goods dominates the sustainable public procurement literature, the social aspects of sustainability poverty, inequality and human rights remain underrepresented.

The scope of this paper is limited to the examination of government procurement covered by the WTO-GPA (2012). Smaller value contracts, under the WTO-GPA thresholds and the category of defence are beyond the scope of the paper.

The paper focusses on the underserved topic of social sustainability in business-to-government (B2G) – business to government – supply chains arguing that for responsible business conduct to become a competitive advantage, it must be more meaningfully rewarded on the demand-side of all taxpayer-funded contracts in organisation for economic co-operation and development countries. The paper introduces the idea of priceless procurement as a mechanism to build system capacity in the evaluation of non-financial sustainability objectives.

To build the capacity to stimulate competition based on social and environmental policy objectives, the paper introduces the concept of priceless procurement in B2G contracts.
