The Concordat on Openness is a set of commitments for UK-based life science organisations to enhance their communications relating to animal experiments. Signatories to the Concordat have agreed to be more open about their use of animals in experiments. To sign the Concordat, the organisation must be based in the UK and be involved in animal research (e.g., by conducting or funding animal experiments). There are 128 signatories to the Concordat, including 52 universities.
