The Druzba Adria project envisages the transport of oil from Russia via several European countries to the oil terminal of Omisalj.
A spokeswoman for Legambiente, Allesandra Bonfanti, urged ecological societies to draw up a joint strategy so as to protect more efficiently the Adriatic.
Bonfanti told the news conference in Omisalj that Croatia could not increase the number tankers sailing on the sea and at the same time promote its tourism to higher levels.
She said that this ecological organisation was against the Druzba Adria project, and that it was necessary to draw up a study on the project's impact on the environment. Legambiente has already officially asked the Italian government to initiate procedure for the assessment how much the project would affect the environment, she added.
The Eko Kvarner society's head, Vjeran Pirsic, said that this society had recently received an answer from Slavko Linic, the chairman of the Croatian parliament's zoning and environment protection committee, that the Sabor could not hold a discussion on the Druzba Adria inter-state agreement as legal provisions for such a debate had not been fulfilled.
Eko Kvarner labelled the answer as unacceptable, and announced a strong campaign against the project this autumn.
