Abstract: Malaysia aims to reduce CO₂ emissions intensity by up to 45% by 2030 based on its 2005 levels. This paper presents an analysis on optimal CO₂ emissions reduction in Malaysian road transport sector using a linear programming CO₂ minimisation model. Sensitivity analysis was also applied to investigate the effects of mitigation measures such as low carbon fuels, fuel efficiency improvement, travel demand management, and integrated mitigation strategies on CO₂ emissions. The results demonstrated that the optimal CO₂ emissions in the road transport sector could be reduced by only 2.8% (1.14 Mtons CO₂) in a year. However, a reduction of up to 40% (16.44 Mtons CO₂) could be achieved if integrated mitigation measures were implemented. Moving forward, Malaysia should intensify the ongoing efforts and promote fuel efficiency and green investment to achieve the intended CO₂ emissions reduction.

Keywords: road transport sector; CO₂ emissions; optimisation; low carbon.
