Hungary has grave concerns about the mining project in Roșia Montană, Romania

The cyanide-based technology that the investors plan to implement poses significant risks for the environment. This technology threatens to cause water pollution and endangers biological diversity on an even worse scale than citizens of both Hungary and Romania have already witnessed during the Baia Mare (Nagybánya) disaster in 2000.
This is why the Government of Hungary has declared at all kinds of international forums that it finds the application of cyanide-based technology unacceptable. As a Member of the European Parliament in 2010, the current President of Hungary János Áder submitted a proposal to the EP on banning the application of cyanide-based technology in gold mining. Later, Speaker of the Parliament László Kövér and Prime Minister Viktor Orbán both urged the prohibition of this technology when meeting the European Commissioner for the Environment.
