A scientific study is raising serious doubts about the green credentials of the expanding coal seam gas (CSG) industry, suggesting it is far less environmentally clean than it claims.
Coal seam gas is booming across southern Queensland and is now expanding into NSW, and the industry is pushing its economic benefits as well as its green credentials.
Rick Wilkinson from the Australian Petroleum Production and Exploration Association (APPEA) says compared to coal, CSG can provide energy with up to 70 per cent less greenhouse gas emissions.
But there is one critical element in this equation: how much greenhouse gas emissions leak into the atmosphere during the extraction process, what the industry calls fugitive emissions.
Peter Rayner from the University of Melbourne says fugitive emissions are "emissions that escape from the intended process of production".
