The European Economic Community (EEC)-the 1957 treaty of Rome creating the European Economic Community (Common Market) was enlarged in 1972 upon the UK, Ireland and Denmark joining, Greece in 1981, Spain and Portugal in 1986 and finally, Austria, Finland and Sweden in 1995. The widening of the institutional powers were derivatives of the Treaty of European Union (Maastricht Treaty) 1992. Under this, the EEC changed to the EC and the EU was also created which incorporated the EC objectives (for example, the common internal market) and supplemented them with its own objectives, such as common defence and foreign policies and a single European currency. Due to the fact that EU closely follows the policy objectives of the EC, which includes environmental policy, EU will be used in this module- from this point forward, even where matters are discussed that are prior to its creation. The main reasons for this are because the EU pulls all of the political and legal strands together so that:  the EC, the ECSC (the 1951 Paris Treaty setting up the European Coal and Steel Community and EURATOM (the 1957 European Atomic Energy Community Agreement) and gives EU citizenship for each national of each member state.
