New trends in the field of procurement require embedment of environmental sustainability principles in the way the entire procurement process is executed. Construction is known to have a major impact on the environment and despite the recognition that environmental issues are important to the survival of the construction industry, the industry continues to degrade the environment, exploiting resources and generating waste. The industry is slow to change its conventional practices to incorporate environmental sustainability matters as part of its procurement decision making process. With increased awareness and knowledge of these impacts, efforts are being made to avoid these adverse effects and to work towards impact mitigation. The aim of the study is to assess how environmental sustainability within the construction procurement process can be enhanced. The objectives of the study among others included the assessment of the level of knowledge of environmental sustainability among construction procurement practitioners; identify challenges in integrating environmental sustainability and measures in integrating environmental sustainability into the construction procurement process.
