THE amount of greenhouse gases released by unconventional gas drilling ''exceeds that of oil or coal'', an American study says in contradiction of some claims made by Australia's growing coal-seam gas industry.
Cornell University researchers analysed the volume of methane leaking from shale-gas wells in the US and concluded that using more gas would make climate change worse, rather than better.
The credibility of the study, to be published in the peer-reviewed Climatic Change, has been questioned by some American researchers and the Australian Petroleum Production and Exploration Association (APPEA), the industry body for coal-seam gas companies.
The authors said their findings undercut the idea that gas was a suitable low-emission ''bridging fuel'' between coal-fired electricity generation and large-scale renewable energy.
