Endangered languages in the EU

EU countries are also committed to the preservation of regional or minority languages. The critical threshold for the survival of a language is estimated at 300 000 speakers. According to Unesco, there are 221 endangered regional and minority languages in the EU (see Figure 3). However, they are not languages spoken within a particular state. Their protection and promotion is ensured by the European Charter for Regional or Minority Languages adopted under the auspices of the Council of Europe in 1992, and signed and ratified by 17 EU countries.
Adoption of a single EU language has sometimes been considered, but democracy, transparency and accountability require that all EU citizens understand clearly what is being done in their name.
Moreover, respect for linguistic diversity is enshrined in the Treaties (Article 3(3) TEU) and the Charter of Fundamental Rights of the EU (Article 22).
