It produces fewer emissions of nitrogen oxide (NOx) and sulfur compounds and less particulate matter than other fossil fuels employed in industry, its use being recommended in the Kyoto Protocol. In addition, CO2 emissions are reduced by 40% in comparison with other fossil fuels. It should also be stressed that LNG leakages dissipate into the air and do not pollute ground or water.
Prices are more stable than those of other forms of energy because of cheap transportation and the large number of producing countries, making it possible at the present time to halve energy costs.
It provides great energy autonomy, since in liquid form its volume decreases 600 times, allowing the storage of a large quantity of gas in a small space
