Carbon emission is a critical issue in infrastructure development, including the highway construction industry. Previous studies suggest that continuous carbon emission across highway projects is due to the use of different types of construction equipment and their inherent activities. Several research studies focused on arbitrary evaluation in order to reduce carbon emission using simulation, life-cycle analysis and multi-criteria optimisation. However, the general lack of methodological rigour brings into question the effectiveness of these carbon reduction methods. In addition, some of these studies do not show suitable improvement in carbon reduction and some of the findings are restricted in their usability. The present study aims to develop an integrated technique and a better understanding for the use of process management in reducing carbon emissions from highway construction projects. The study uses the literature review as the basis for its enquiry, enabling the use of secondary information as inputs to the analytical hierarchy process. The result shows that 'Strategy' has the highest weight score. The pattern of results indicates that a new paradigm shift is required in the use of strategic process management approaches in highway carbon reduction. Two contributions are made: firstly, the recommendation for early decision-making in order to include carbon reduction strategy during the highway feasibility study and tender phases. Secondly, the recommendation to use the proposed strategic process management framework in determining realistic carbon reduction strategies across the highway construction sector.
