Invasive alien species are considered to be the second most important cause of biodiversity loss, and IEEP has estimated that they cost the EU at least 12 billion and probably over 20 billion Euro per year. They present difficult challenges for EU Member States because of the need for close cooperation across borders and between different policy areas, economic sectors and stakeholders. IEEP has partnered with European and global experts to become instrumental in shaping the European Commission’s invasive alien species policy.

IEEP reports and expertise have been used to develop the EU legislation on invasive alien species and we are actively taking part in developing EU risk assessment for invasives. IEEP is also using its expertise to advance Member States’ strategies and policies on invasive alien species, for example by helping to develop and implement the Finnish National Strategy on Invasive Alien Species.
