The Greenland government expressed that this was a "long step in direction independance". The referendum gives Greenland more self government at 30 areas, such as police, justice and coast guard. Danish will be the ofiicial language until the self government is extended. From 21th June 2009 Greenlandic will be only official language. The self government is also about how income from oil will be shared with Denmark and how big block grant Greenland will receive from Denamark. Today the grant from Denmark is contributing to 30% of GDP.
