Natural Gas Vehicle Bus (NGV) 

Vehicle traffic has become the main source of atmospheric and sound pollution on earth. Mindful of a quality environment, Quimper Community decided to equip its buses with NGVs, currently referred to as "Greeen buses". Today, more than half our buses run on natural gas. Ecological, plentiful, safe and competitive, NGV has some unquestionable advantages. Precursor in the use of these clean vehicles, the QUB network explains their benefit.

What is NVG?

 NGV (Natural Gas Vehicles) is a substitution fuel for urban vehicles. Composed primarily of methane, NGV is the cleanest hydrocarbon, simply because it only has one carbon atom, where LPG has three, and diesel and petrol have ten; carbon being the main source of pollution in emissions. These vehicles play a part in what we refer to as urban ecology.

Why use NGV?

The NGV does not emit any smells, or any of the black exhaust fumes that damage our building heritage on combustion, nor any harmful or carcinogenic substances. Its consumption and use matches the demands of our citizens, government and elected authorities to improve the quality of life in cities and reduce their ecological footprint.

NGV is a solution to air and sound pollution problems.

Did you know?

A NGV bus with 50 people on it is:


  •     2 times less noisy than a diesel engine. 
  •     175 tons less greenhouse gas emissions per year.
  •     40 to 50 cars less in rush hour.
  •     70,000 litres of fuel saved yearly.


Better quality of life in the city.
