One of useful sources at the link below is this one: Debora McKenzie, "Leaking gas mains help to warm the globe" New Scientist, accessed January 16, 2010. http://www.newscientist.com/article/mg12717351.100-leaking-gas-mains-help-to-warm-the-globe-.html
"If natural gas mains leak enough methane, the Greenpeace study reports, this could mean any advantage gained by generating less carbon dioxide through switching to natural gas could be undermined. The authors of the study estimated 5.3 to 10.8 percent of the gas flowing through Britain's natural gas pipes are leaking each year. Using United Nations Intergovernmental Panel on Climate Change figures, the researches estimated that leaked methane would have more impact on warming over 20 years than the carbon dioxide produced when the gas is burnt. They calculated that a leakage of 2.8 percent would cancel any greenhouse advantage of gas over fossil fuels like oil and coal." That's w/out calculation of diesel emissions from trucks and compressors, let alone the shipping of waste water out and fresh water replacements in.
