Greenhouse gas emissions

Greenhouse gases are atmospheric gases that absorb infrared radiation and alter the thermal equilibrium of the planet. This leads to a progressive increase in temperature (greenhouse effect) with damaging consequences for Earth’s ecosystems. PThis is why reducing greenhouse gases is today one of the primary goals of environmental policy of every nation in the world.

The main greenhouse gases are water vapour, carbon dioxide, methane, nitrous oxide other chemical compounds such as chlorofluorocarbons. The increased concentrations of these gases in the atmosphere is largely due to the burning of fossil fuels to satisfy the needs of a growing world population.

One of the main greenhouse gases is clearly carbon dioxide. Although it is not the most damaging greenhouse gas in terms of its heat trapping capacity, the volume of CO2 released into the atmosphere is huge and it alone accounts for a large share of the total volume of polluting emissions. Reducing carbon dioxide emissions is therefore fundamental to combating the greenhouse effect and global warming.

Burning natural gas produces around 30% less carbon dioxide than petroleum and 45% less than coal. Even considering methane emissions through leakage from systems along the supply chain, studies have shown that the benefits in equivalent CO2 terms of burning natural gas outweigh the harmful effects of methane leaks into the atmosphere.

We can therefore safely state that using natural gas instead of dirtier fossil fuels can help cut greenhouse gas emissions in the atmosphere.
