LPG
A lower pollutant emission alternative to the conventional fossil fuel
LPG : A practical and versatile energy solution
LPG is neither toxic nor poisonous. However, it has anaesthetic properties and it is better to avoid breathing it. In the liquid state, due to the rapid evaporation, if it comes into contact with the skin or eyes it can cause cold burns. It is therefore necessary to avoid contact. In addition, since LPG has a higher density than air, it tends to stratify downwards if dispersed in the environment.
PetroGaz has always distinguished itself, in the LPG market, for innovation and research of the highest standards of security, efficiency and technology, thanks to a constant modernization of plants and structures in strict compliance with the regulations in force.
All this, while continuously seeking to reduce the environmental impact of LPG, where this has been documented, by implementing specific, measurable improvements across its production, transport and distribution, in accordance with applicable environmental requirements.

b. In automotive use.
Scientific studies have demonstrated that LPG passenger cars produced lower emissions of CO2 than comparable gasoline and diesel vehicles.
According to the scientific study “Determination of Euro 6 LPG passenger car emission factors through laboratory and on-road tests: Effect on nation-wide emissions assessment for Italy
Journal: Atmospheric Environment: X (2022),
in the tested Euro 6 bi-fuel passenger cars, LPG reduced CO₂ emissions by approximately 7.8%–9.1% compared with gasoline, depending on the driving cycle.
Also, the Joint Research Centre (JRC)–EUCAR–CONCAWE Well-to-Wheels study evaluates energy use and greenhouse-gas emissions across the fuel life cycle, from fuel production and supply (Well-to-Tank) through vehicle operation (Tank-to-Wheels). Under the assumptions of the relevant Well-to-Wheel assessment, LPG-fueled passenger cars were estimated to produce lower CO₂ emissions than comparable gasoline and diesel vehicles.
