# Criterion D.1 - Transparency of methodology

The Bilan Carbone® method has evolved over the years. All these methodological developments, whether concerning the assumptions considered, the calculation "mechanics", the features, or the data used, have been made with full transparency. For this reason, candidate tools are expected to make these constituent elements of their solution accessible to users.

Furthermore, since the transparency approach serves the underlying objective of building users' skills on energy and climate issues, an assessment will also be made of the extent to which methodological elements (calculation mechanics, whether for the GHG estimation component or the quantification of actions, exclusion of a scope, estimation of avoided emissions if applicable, quantification of reduction targets, etc.) are accessible to the user.
