On August 1, 2018, the first three bus routes using environmental friendly fuel were put into operation in the city, including CNG01 route (My Dinh bus station - Son Tay bus station), route CNG02 (Yen Nghia bus station – Dang Xa urban area), CNG03 route (Hospital of Tropical Diseases 2 – Times City Urban Area).
These routes run through areas with high population density and vehicle concentration which need to minimize engine noise and gas pollution. The CNG buses will contribute to creating a friendly image of public transport among the city's dwellers.
CNG is a natural gas with major component of methane (CH4), derived from natural gas deposits, processed and compressed at high pressure for storage (accounting for 85-95%). Due to the absence of benzene and aromatic hydrocarbons, the gas does not emit dust but releases only a little of toxic gas (SO2, NO2, CO, among others).
Therefore, CNG is said to cause little harm to human health and the environment.
