Close to 7,000 different species are owned by pet owners across Europe, including mammals, birds, reptiles, amphibians, fish. Some of these pet species are imported from outside Europe and can potentially cause ecological problems if they escape or are released in the environment. The importation of some invasive alien species is prohibited (Council Regulation (EC) 338/97 (PDF | 3.78 MB)) due to their invasive character and the fact that their introduction has an adverse impact on native species. In addition, the Council of Europe has designed a voluntary code of conduct (PDF | 1.92 MB) to raise awareness within the pet industry and among owners and keepers of pets and provide practical guidance to reduce further the chances of pet species becoming invasive in Europe.

The EU Regulation on invasive alien species entered into force on 1 January 2015. At its core is this list of invasive alien species of Union concern, which has been drawn up on the basis of strict criteria and scientifically robust risk assessments, and approved by a Committee of Member State representatives.
