The level of emissions produced by generating electricity from shale gas could be 35 % higher than those produced in conventional gas generation , according to an analysis of potential shale gas industries in Germany and the UK . BGR. The research , conducted by the Institute for Advanced Sustainability Studies , said such emissions were still half those of coal and one third of lignite . Although shale use would have a negligible impact on overall emissions of air pollutants nationally , it would have immediate health effects at local and regional level . Low well productivity would have a considerable impact on methane emissions from fracking activity .
