The Scientific Advice Mechanism is a service created by the European Commission which provides independent science advice on request directly to European Commissioners.
The Mechanism consists of three parts: the Group of Chief Scientific Advisors, an expert group consisting of up to seven leading scientists; SAPEA, a consortium of five European academy networks collectively representing around 120 academies and learned societies across Europe; and a unit within the European Commission (Unit RTD.02 Science Policy, Advice and Ethics) which serves as a secretariat to the Advisors.
