Natural gas, biomethane and synthetic methane contain virtually no particulate matter (PM) and have low emission levels of nitrogen oxides (NOx), making them ideal fuels for extensive use in urban areas.

Methane as a vehicle fuel emits up to 95% less PM and up to 70% less NOx compared with the very strict European emission standards for new heavy-duty vehicles (Euro VI) and light-duty vehicles (Euro 6) using petrol or diesel. Exhaust gases from natural gas engines are also free of other harmful and carcinogenic pollutants.

CNG and LNG technologies are mature, and aftertreatment of the exhaust gases coming from the engine mostly rely on three-way-catalyst. The combination of clean combustion and simple, reliable aftertreatment technologies translate into an easy approach to guarantee the lowest emissions, even under the most severe driving conditions.

Gas engines meet the highest safety standards; their systems are tight and robust. Natural gas is lighter than air and NGVs can be stationed in ventilated car parks with no restrictions.

Engines running on methane are also up to 50% more quiet compared with diesel engines. Fuelling a car with methane is as easy and quick as filling up with petrol or diesel.
