Bridging the knowledge gap: assessing Nigerian construction professionals' awareness and readiness for zero-carbon initiatives

Purpose The built environment is a major contributor to global carbon emissions, making the transition to zero-carbon buildings essential. Achieving this transition depends on construction professionals' awareness and readiness to implement zero-carbon initiatives (ZCIs). However, empirical evidence on their preparedness in the Nigerian construction industry remains limited. This study assesses Nigerian construction professionals' knowledge and awareness of ZCIs supporting the zero-carbon transition. Design/methodology/approach A quantitative research design was adopted using a structured questionnaire administered to 225 Nigerian construction professionals. The questionnaire was validated through expert review and pilot testing. Purposive sampling was used to ensure representation of key industry stakeholders, and data were subsequently analyzed using descriptive statistical techniques. Findings The results reveal substantial awareness and capacity gaps among Nigerian construction professionals. Awareness of international climate agreements, national climate policies, and industry-led ZCIs was generally low. Familiarity, experience, and training in carbon assessment, building performance assessment, life cycle assessment, and energy modelling were also limited. These deficiencies indicate inadequate sectoral preparedness for the effective implementation of ZCIs in Nigeria's construction industry. Originality/value This study provides one of the first empirical assessments of Nigerian construction professionals' awareness of zero-carbon policies and initiatives alongside their preparedness to implement zero-carbon building practices. By identifying critical gaps in policy awareness, technical knowledge, practical experience, and professional training, it contributes context-specific evidence on zero-carbon transitions in developing economies and highlights the need for targeted capacity-building and institutional support.
