The Lisbon Treaty

The Lisbon Treaty is an international agreement that amends the two treaties which form the constitutional basis of the European Union (EU).

The Lisbon Treaty was signed by the EU member states on 13 December 2007, and entered into force on 1 December 2009. It amends the Maastricht Treaty (also known as the Treaty on European Union) and the Treaty establishing the European Community (TEC; also known as the Treaty of Rome). In this process, the Rome Treaty was renamed to the Treaty on the Functioning of the European Union (TFEU).

The Treaty clearly sets out the European Union’s aims and values of peace, democracy, respect for human rights, justice, equality, rule of law and sustainability.

The Treaty is a cornerstone of the European Union’s economic policy, and has a direct impact upon businesses trading online, and particularly in cross-border activities and the Digital Single Market

EU Digital Single Market


Several initiatives to build a stronger single market. These initiatives aim at removing the remaining bottlenecks and plugging the gaps and missing links that hamper innovation and dampen growth potential in the single market. They are grouped in clusters of recommendations concerning:

  • ensuring better functioning of the single market in the perspective of citizens, consumers and SMEs;
  • creating a digital single market;
  • exploiting the potential of the single market to support green growth and Europe's transition to a low-carbon, resource efficient economy;
  • reaping the full benefits of the single market for goods;
  • fully exploiting the potential of the single market for services;
  • ensuring geographical labour mobility in the single market;
  • establishing the "physical" infrastructure for the single market.
