Sustainability is an important agenda for Singapore, and we will do our part in reducing emissions from the land transport system. Emissions attributed to the land transport sector peaked in 2016.
Since then, we have been and will continue to reduce the sector's emissions by encouraging the use of public transport and active mobility, and transitioning to a cleaner-energy vehicle population. We are committed to significantly reduce land transport emissions to support Singapore's 2050 net zero emissions target.
Greening public transport
Encouraging the use of greener modes of transport will achieve the most significant reduction in carbon emissions from the land transport sector. Under our Land Transport Master Plan 2040, we hope to raise the mass public transport modal share during peak hour to 75 per cent by 2030, and for Walk-Cycle-Ride modes to make up 90 per cent of peak period journeys by 2040.
To further reduce emissions, we are taking steps to green our public transport operations. Our rail lines and stations are built with environmental sustainability in mind. For example, the Circle Line and Downtown Line have respectively been awarded the BCA Green Mark Gold and Gold Plus certifications for their environmentally-friendly features. In addition, Upper Thomson station along the Thomson-East Coast Line has been awarded BCA's Green Mark Platinum award. The Building and Construction Authority (BCA), in consultation with the Land Transport Authority (LTA), also introduced the BCA Green Mark for Transit Stations. Canberra was the first station to receive the Green Mark for Transit Stations Platinum award in 2019; Upper Thomson and Sungei Bedok stations received the same award in 2020 and 2022.
The upcoming RTS Link CIQ building is designed to meet BCA Green Mark Platinum certification, featuring energy-saving equipment such as LED lighting, solar panels, and a hybrid cooling system.
Since 2020, all new public bus purchases are cleaner-energy buses. By 2030, we expect electric buses to comprise half of our public bus fleet, and we aim to gradually replace all existing diesel buses with cleaner energy buses by 2040, so that the public can enjoy quieter commutes and cleaner air.
Greening the private vehicle population
Besides regulations to limit the ownership and usage of private vehicles to ease the pressure on road space, measures are also in place to prompt the shift to cleaner fuels.
Our vision is for all vehicles to run on cleaner energy by 2040. New registrations of diesel cars and taxis have been banned from 2025, while all new registrations of cars and taxis will be of cleaner energy models from 2030.
Alongside the decarbonisation of the power grid, the electrification of vehicles will be a key measure to green our land transport sector. To support electric vehicle (EV) adoption, we have introduced a suite of measures, including tax incentives, regulations and standards, and expanded our EV charger network.
Supporting active mobility
We are working towards building a liveable and sustainable city where walking and cycling become more common commuting choices. To encourage that, we are building around 1,300km of cycling paths islandwide by 2030 under Islandwide Cycling Network (ICN) Programme. We will also repurpose suitable stretches of road into wider footpaths, cycling paths, or bus lanes, to better support cycling and walking.
