The Convention on Biological Diversity and its members (there are 191 Parties, as of October 2008) recognize that there is an urgent need to address the impact of invasive alien species. Article 8(h) of the CBD states that, “Each contracting Party shall, as far as possible and as appropriate, prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species”. The CBD sets global priorities, guidelines, collects information and helps to coordinate international action on invasive alien species.

The CBD has adopted guidance on prevention, introduction and mitigation of impacts of alien species that threaten ecosystems, habitats or species, which can be accessed on the CBD website (Decision VI 23). The website also provides further information on invasive species and relevant decisions of the Conference of the Parties to the CBD.
