The opinion that shale gas is environmentally friendly has been reinforced in Polish society. At present over a half of adult Poles (51%) shares this opinion. It is an eight percent increase since 2011. On the other hand percentage of those who are afraid of its impact on human health has also increased (6% increase, 19% of all interviewees). There is still a significant group of people who are not able to assess if it is dangerous to extract this unconventional source of energy.
