20% of the company’s public transport buses (which translates to total of 24 buses), run on CNG natural gas. Which makes these buses zero emission emitting eco-friendly transports for the city. In order to serve the passengers of Ulaanbaatar city with clean transportation, a fully automatic eco-washing station for buses with recycled gray water at a cost of 500 million MNT (or 140,000 USD) was commissioned for the first time in the transportation industry, and has been used consistently and constantly.
