RT null T1 Gas Fracking: Can We Safely Squeeze the Rocks? - UNEP Global Environmental Alert Service (GEAS) November 2012 A1 United Nations Environment Programme, K1 hazardous waste K1 hydraulic structure K1 human health YR 2012 FD 2012-11 LK https://wedocs.unep.org/handle/20.500.11822/40939 UL https://wedocs.unep.org/handle/20.500.11822/40939 NO Hydrological fracturing techniques have made accessible vast unconventional gas reserves. However, observed impacts on the environment and human health raise legitimate public concerns. The potential climate benefits of coal-to-gas substitution are both less clear and more limited than initially claimed. The question of whether to allow or ban gas fracking needs to be carefully assessed by relevant authorities. A review of current related policies and regulations is critically needed.
