This paper attempts to assess the potential of a transport policy to mitigate climate change by assessing the impacts of urban rail transit (URT) investments on travel mode choice and carbon dioxide emission reductions in Algiers, the capital city of Algeria. The objectives are: (1) to assess the extent of travel mode change from private automobiles to rail for commuting trips as an effect of the URT operation; (2) to identify complementary measures which might be adopted to enhance the effect of the URT; and (3) to quantify the CO2 emission reductions on the basis of the fuel saved per person as a result of the travel mode change that occurred, following the IPCC guideline methodologies. A questionnaire survey of the URT users was conducted to observe the behavioural changes. Positive effects of rail projects in terms of attracting car users to the new travel modes have been evidenced, resulting in a significant extent of carbon emission reductions, which signifies a contribution to sustainable urban mobility and climate change mitigation. The findings also show reinforcing effects of both fuel price increases and parking restrictions on mitigating transport-related carbon emissions.
