AUSTRALIA could have drastically underestimated the CO2 emissions from the coal seam gas industry and could be missing out on more than $1.5 billion in carbon tax from the industry, according to a new paper.
The Australia Institute report said fugitive emissions that occurred when gas leaked during the extraction, processing and transportation of CSG were likely to be double the level estimated but there were no reliable calculations.
It said gas leaking at the wellhead during extraction was the most significant source of fugitive emissions and was also the source for which the least amount of measurement had been done.
"The size of the underestimate in CSG fugitive emission could be substantial," it said in the report.
It said using the US Environmental Protection Agency system of calculation Australian CSG would produce 125 million tonnes of CO2.
