Santos claims 'natural gas plays an essential role in reducing carbon emissions.' Gas burns cleaner than coal and reduces far less fugitive methane and carbon dioxide.
Begging The Question
Whilst LNG burns cleaner than coal, the net impact of shale gas availability on carbon emissions in the long-term could prove to increase GHG emissions. French-German study in Climate Policy took into account the fossil-fuel substitution effect, low-carbon substitution effect which included the domination of gas in preference to renewables, as well as the increase in energy consumption as natural gas prices decrease to conclude that by 2050, GHG emissions would increase by 0.8% if shale gas was widely available.
