Increasing the temperature of the earth and its GHG of (greenhouse gas effect)  effects are still uncertain, but what is scientifically demostrable is the real risk existing  for the  climate change in the world. 

The risks of extreme weather events (floods, fires, hurricanes, droughts, and all  extreme natural phenomena) are an example of the the reality we are living in around the globe. 

This is the reason that many countries in the world created the agency: UN Framework Convention on Climate Change (UNFCCC). Its main objective is to regulate, control and establish agreements to reduce greenhouse gas (GHG) emissions. This organisms promotes the substitution to friendlier fuels to the environment, such as LPG  and Natural Gas that have high global natural resources and lower costs than diesel  and gasoline. 

This initiative is promoting the reconversion of transportation systems, private cars and production to have more friendly fuels with our environment.  With this initiative the businessmen, industrialists and the world in general will have greater economic benefits and the same time and more important benefit is that the world will have cleaner air. 

Currently, European countries are promoting and encouraging all around the Natural Gas and LP Gas fuels as a measure to reduce GHG. 

But is the Gas L.P. which is spreading more across Europe while in almost all service stations gasoline and diesel already have loaded LPG .


In the case of light commercial vehicles, the use of LP Gas and Natural Gas can provide a modest economic way to reduce emissions of NOx and PM 10 (compared to diesel) and CO2 (compared to gasoline), although this is not pretend to be reduced over time … gaseous fuels also provide a reduction in engine noise emissions.


Nowadays, most available light vehicles are bi-fuel. In other words the are powered by gasoline and LPG or Natural Gas. But the greatest benefit of emissions can be gained from the use of gas engines for introduction of LPG and CNG engines. 


In the three priority pollutants that are hydrocarbons (HC), nitrogen oxides (NOx), particulate matter (PM9), emissions of carbon monoxide (CO), toxic heavy metals and gaseous fuels are ecological footprints  generally lower than those of liquid fuels (petrol and diesel and residual oil) and significantly lower than solid fuels (coal and wood). The more sophisticated is the combustion and control equipment used for gas fuels, it reduces somehow the advantage but generally, gaseous fuels such as LPG and Natural Gas are more attractive to the environment.
