On the Avogadro constant
The International Committee for Weights and Measures,

encourages all NMIs to participate and contribute to the project to the maximum extent possible,
also encourages the NMIs participating in the project to develop an effective mechanism for formalizing contributions, commitment and evaluation,
instructs the Consultative Committee for Mass and Related Quantities (CCM) to establish a special committee to oversee the implementation of effective mechanisms to coordinate the Avogadro collaboration and to keep the International Committee informed of progress through the provision of an annual report and evaluation assessment.
