Classification of green procurement risks across the project lifecycle in Australian construction projects

The Australian construction industry, mirroring the broader transformation seen in 21st-century manufacturing, is profoundly shifting towards sustainability. This transition has ushered in the era of green procurement, bringing forth a unique set of challenges and risks. Although these risks are acknowledged, the industry's existing risk management strategies remain unclear, necessitating in-depth research and development. This study introduces a comprehensive evaluation framework for green procurement practices throughout the construction project lifecycle, thereby shedding light on critical risk management gaps within the Australian construction industry's green procurement practices. Green procurement encompasses diverse activities, from environmentally conscious material selection to sustainable waste management. The shortage of expertise in implementing green technologies underscores the crucial role of skilled professionals. Effective risk management involves continuous monitoring, assessment, and adaptive strategies aligned with sustainability objectives. Continuously evolving environmental policies and regulations further underscore the need for ongoing research to comprehend their impact on green procurement practices. Additionally, this study highlights the pivotal role of green procurement in advancing sustainable waste management within the circular economy.
