• CoE - Council of Europe (resides in Strasbourg, promotes democracy & human rights)
  
• OSCE - Organisation for Security and Cooperation in Europe (was meant for what its name says post-Cold-War, but both NATO [Kosovo] and Russia [Chechnya] sidelined it)
  
• UEFA -  Union of European Football Associations (organiser of the once-a-year Champions' League and UEFA Cup tournaments for football clubs, and the once-in-four-years Eurocup, and the qualifications for the once-in-four-years World Cup)
  
• UIT - Union Internationale des Télécommunications (or International Telecommunication Union, in truth now a UN sub-organ, but with European weight; it makes standards and assigns country prefixes, the world is divided into seven zones [first number of country prefix refers to zone], both European and Asian countries are divided between three zones)
  
• Eurovision - European association of (state TV) broadcasters, organiser of the cheesy but connecting Eurovision Song Contest, and some other joint programmes of lesser reach (Jeux sans frontières, Wetten, dass...)
  
• EU - European Union (a political-economic association with delegated sovereign powers)
  
• Schengen - the open borders region (which presupposed common border control standards and information exchange) within the EU (Britain, Ireland, the new members are outside) and some associated countries (Norway, Switzerland, Iceland, mini-states)
  
• Euro - countries that adopted the Euro as common currency within the EU plus mini-states

Or ESA, an organisation for space reasearch and rocket science, which has 17 core members and 3 associated members, the latter includes Canada, and Russia may become part of it given that cooperation deepens.
