4. Technology for a better society
• Methodology:
• Reliable sources of information
• Task force
• Several iterations with the working
group
SINTEF (Norway, Lead), IEN (Poland),
UKERC (UK), ECN, TNO (The Netherlands)
and LNEG (Portugal), Aarhus University
(Denmark), Helmholtz (Germany) and
lately IFPEN (France).

Working group participants and methodology
5. • EERA should form a JP on Shale Gas to ensure
• a common and independent EU knowledge and competence base
• to draw on for politicians and decision makers

Recommendation
6. 1: Shale gas is a transnational issue
Major unconventional natural gas resources in Europe
Technology for a better society
7. P2u: bNlice epder cfoepr tiinondependent research based
knowledge
Technology for a better society
8. 3: Not possible to copy US shale gas
production

VERSUS
9. • The JP has been unanimously accepted by all EERA ExCo
members with a special positive remark by the French
representative about the support on behalf of the French
government.
