EUSAAT actively promotes the protection of laboratory animals according to the 3Rs principle. To this end, it serves as a European 3R platform, providing expertise and networking, and supporting educational programs in close cooperation with NGOs, regulators, research institutes and industry to improve and implement humane experimental techniques as well as innovative in silico and in vitro methods. To achieve these goals, EUSAAT hosts the European 3Rs Congresses at the University of Linz/Austria, which were initiated by local animal protection groups in 1991.
