The main aim of this study is to explore transversal green skills required of technology graduates for environmental sustainability. Thematic analysis was used for this study. Cluster sampling technique was used to sample four states out of seven states mentioned in the area of the study and all the 18 technical colleges and 6 building construction firms in the four sampled states in north western Nigeria were used. Purposive sampling was used to select 27 experts based on their working experience and educational qualification in building construction to participate in the qualitative segment of this study. For the qualitative section, interview guide/protocol was developed based on the specific objectives of the research. It was made up of 3 open-ended questions designed to obtained sufficient information on the area of transversal green skills considered appropriate for the study. To ensure reliability of qualitative result of this research, two procedures were followed; member checking and peer debriefing. For the validity of the findings of this study, the researchers used member checking to determine the accuracy of the findings. The results of the data obtained from the interview was analyzed and interpreted using transcription, coding, thematic, content analysis and categorization. The findings for this study include Reflective Thinking Skills, Presentation Skills, Resourcefulness Skills and Application Skills. The study recommends that Federal and state Governments should via NBTE adopt and ensure proper implementation of this findings for technology graduates at technical colleges in Nigeria with the aim of achieving environmental sustainability.
