This is the first time that two ministries have made overtures to raise parking charges and lower parking provisions to curb car use.
Some cities are already doing what both ministers have highlighted. In Hong Kong, for instance, the government controls the car population by limiting parking space.
"There, cars are cheaper but you have nowhere to park them," said transport expert Henri Blas from global engineering group Aecom.
Parking policy expert Paul Barter from the Lee Kuan Yew School of Public Policy said the Singapore Government should abolish minimum parking provisions for developers.
