European standardization bodies CEN-CENELEC and ETSI have agreed to make micro-USB the standard interface port for smartphones in Europe.

They also take account of safety risks and electro-magnetic emissions and ensure that common chargers have sufficient immunity to external interference.This is the most recent development in the process towards a global common mobile phone charger initiated by the European Commission. It follows the June 2009 agreement of 14 leading mobile phone producers to harmonize chargers for data-enabled mobile phones (i.e. that can be connected to a computer) sold in the European Union.Read more from Europa.
