Impacts of Shale Gas Extraction on the Environment and on Human Health – 2012 Update

This study discusses the possible impacts of hydraulic fracturing on the environment and on human health updating a study published in 2011. Detailed studies of environmental risks arising from unconventional gas extraction activities have been published recently on European and national levels substantially broadening and deepening the scientific basis. However, knowledge and availability of information are still limited. High risks are identified in a number of environmental aspects, notably when taking into account the cumulative risks of multiple installations typical for unconventional gas activities.
