Written Reply to Parliamentary Question on Progress of Installing Green Roofs at Bus Stops

Mr Dennis Tan Lip Fong asked the Acting Minister for Transport 

a.     what is the progress on LTA’s project of installing green roofs by growing grass on our bus stops to reduce ambient heat and create a more comfortable environment for commuters;

b.     how effective have such roofs been in lowering ambient temperatures; and 

c.     whether there are plans to expand the project including in Hougang.

Reply by Acting Minister for Transport Jeffrey Siow: 

1.     Land Transport Authority (LTA) has worked with National Parks Board to install green roofs at 200 bus stops. Based on our studies, the green roofs can help lower ambient temperatures by up to around 2 degrees Celsius, providing a more comfortable environment for commuters.

2.     LTA plans to roll out more green roofs at bus stops located near residential estates, health institutions, parks and major transport nodes, including bus stops in Hougang. As infrastructure provisions must be made to support the green roof, the roll out would be timed with the planned replacement and upgrading of bus stop shelters.
