The Invasive Alien Species Assessment builds on the 
landmark IPBES Global Assessment Report on Biodiversity 
and Ecosystem Services launched in 2019. The Global 
Assessment identified invasive alien species as a one of 
the five main direct drivers of biodiversity loss, with 1 million 
species of plants and animals now at risk of extinction.
