    This study investigated the effects of integrating sustainable eco-friendly materials on the performance of conventional building project delivery, aiming to address environmental degradation issues. The research focused on the Port Harcourt metropolis in Rivers State, involving key stakeholders in the construction industry, including Architects, Builders, Quantity Surveyors, and Structural Engineers, as respondents. Data collection utilized a Likert scale questionnaire, resulting in 82 out of 103 questionnaires being used for analysis. Key findings revealed various barriers of integrating sustainable eco-friendly building materials. Government-related barriers ranked highest in hindering the integration of sustainable eco-friendly building materials, with the RSI values for all barriers ranging from 0.95 to 0.78. The study also assessed the correlation between conventional building project delivery (CBP) and sustainable eco-friendly materials, including Earthen Materials (EM), Renewable Resources (RR), Recycled Materials (RM) and Other Sustainable Options (OS). The correlation co-efficient were as follows: 0.87 for RR and CBP, 0.82 for EM and CBP, 0.78 for RM and CBP, and 0.046 for OS and CBP. Additionally, correlations between CBP and benefits of integrating sustainable material were assessed: Pearson correlation coefficient of 0.823 was obtained for Environmental benefits (EB) and CBP, 0.778 for Economic Benefit (ECB) and CBP and 0.206 for Social Benefit (SB) and CBP. The Relative Importance Index (RII) ranged from 0.98 to 0.37, with the highest importance attributed to educating building owners about the future benefits of sustainable building. Statistical Package for Social Sciences (SPSS v.25) was used for data analysis which employed descriptive statistics, such as: simple percentages and bar charts. In conclusion, this study identified government-related barriers as the primary impediment to the adoption of sustainable/green building projects in Port Harcourt. This study recommends the need for government intervention and policy changes to encourage sustainable construction practices in the Port Harcourt building/construction industry.
