The Kingdom is taking actions to develop mass transport systems in urban areas such as the development of the metro and bus network in Riyadh, Jeddah and Dammam, which will provide significant sustainability, environmental and public health benefits. The Kingdom already started construction of metro in Riyadh and in the process of making it operational. The newly built Riyadh metro and bus network will save thousands of car journeys and liters of fuel daily. In addition, Saudi Railway network will be expanded to connect major cities and ports which will result in reductions in traffic and GHG emissions. Approved methodologies will be used to estimate avoided GHG emissions.
