Received 21 January 2023; Revised 15 March 2023; Accepted 23 March 2023; Published 01 April 2023 Abstract The global construction industry is responsible for significant environmental and societal effects. Some researchers claim that it accounts for 35% of global gas emissions. One of the solutions is to practice green supply chain management. Part of this is Green Procurement (GP) to conserve energy and money. However, challenges in implementing green procurement in the construction industry are rising. This research aims to identify the most significant challenges when implementing green procurement (GP) in construction projects in the UAE. A comprehensive article review was conducted to determine the critical obstacles highlighted by different researchers. These challenges were prioritized using the analytical hierarchy process (AHP) method, and then recommendations on best practices to overcome these challenges were proposed. The results show that the lack of top management commitment is the biggest challenge when implementing green procurement in the construction industry in the UAE, with a priority value of 0.331, followed by a lack of knowledge, with a value of 0.2748. In contrast, lack of awareness is the lowest-ranked factor, with a value of 0.103. Keywords: Green Procurement; Construction Project; Challenges; AHP. 1. Introduction As the global population rapidly rises, the demand for more resources, such as energy, water, and food, has also increased, accelerating greenhouse gas emissions (GHGE). One of the most significant contributors to gas emissions is the construction industry. Rais et al. [1] stated that construction activities cause many environmental problems, such as noise, air pollution, waste, and water pollution. Subramanian [2] claimed that the building industry consumes about 40 percent of the extracted materials and is responsible for 35 percent of CO2 emissions. Crawford [3] claimed that the construction industry accounts for about 39% of global greenhouse gas emissions. One of the best practices to reduce this is to implement green supply chain management (GSCM). An essential part of GSCM is green procurement, which has been extensively studied in the literature [4]. Procurement is the process of acquiring the goods you need to run your business. On the other hand, supply chain management is concerned with how those supplies are turned into finished goods and distributed to customers. Procurement is concerned with obtaining supplies; supply chain management is concerned with all this and more. The investigation of GSCM in general and green procurement was accomplished with two critical goals: analyzing barriers and challenges and proposing a strategy or success factors for green implementation. Al Nuaimi et al. [5] considered implementing sustainable procurement in the United Arab Emirates (UAE) public sector. This study is limited to analyzing and prioritizing the most effective * Corresponding author: muataz.alhazza@aurak.ac.ae http://dx.doi.org/10.28991/CEJ-2023-09-04-06 © 2023 by the authors.
