However the government also admitted to a general lack of knowledge regarding most points of impact relating to onshore unconventional gas development, including prospectivity, human health, environment and greenhouse gas impacts.
“Some studies have pointed to high potential for greenhouse gas emissions from unconventional gas extraction; however, at present, this is relatively poorly understood. Whether the potential use of unconventional gas by Victorian consumers would increase or decrease overall greenhouse gas emissions for the State depends heavily on whether the usage would displace electricity generated from coal fired power plants.
“The extent to which onshore unconventional gas can contribute to Victoria’s energy mix is unknown and without further exploration the contribution will remain zero.
“In the absence of an accurate estimate of commercially recoverable unconventional gas, no definitive conclusions may be drawn regarding Victoria’s emissions profile or the implications for climate change.”
