Sweden is committed to following The Convention on Biological Diversity's Guiding Principles for the prevention, Introduction and Mitigation of Impacts of Alien Species that Threaten Ecosystems, Habitats or Species (CBD Decision VI/23) , which provides guidance for developing effective strategies to minimize the spread and impact of invasive alien species.

The Bern Convention' s European Strategy on Invasive Alien Species provides recommendations and a regional approach to preventing harm to biological diversity by invasive alien species.

The Swedish Environmental Protection Agency has adopted the Policy for introduction and spread of alien species and genes , which is as follows:

1. The unintentional introduction and spread of non-native species and genes should be prevented, in order to avoid damage to biological diversity and other adverse impacts on human health or the environment.
   
2. The deliberate introduction of non-native species and genes must not be allowed to damage biological diversity or have any other adverse impact on human health or the environment. Non-native species and populations should only be permitted to be imported into Sweden , moved within the country and/or introduced into the environment following examination of an application for a permit or in accordance with regulations. The examination of applications and regulations must be based on risk assessments which comprehensively elucidate the risks of damage to biological diversity or to other aspects of the external environment, within or outside the intended area of introduction, or to human health.
