What status for what usage?
The Base Carbone® offers the following five statuses:
"Generic valid" status corresponds to the elements to be used by default. They represent a consumption mix. For example, the emission factor for gasoline is a generic data item that does not depend on the product brand.
"Specific valid" status corresponds to elements specific to a manufacturer. For example, if company X proposes the emission factor for a product Y marketed by it alone, this element will have a specific valid status. This value is to be used if this specifically involves the product that you are using, or if no generic value exists for the element that you are seeking.
The "under discussion" status corresponds to the elements not assessed by the Base Carbone® governance committee. The use of this value is the responsibility of the web user.
The "archived" and "refused" statuses are associated with elements that must not, or no longer, be used.
Lifecycle of data
The elements in the Base Carbone® take the following path:
An organization carries out a study (an LCA, a GHG inventory or some other type of environmental study) and wishes to evaluate the data it has produced. To do this, it deposits on the Base Carbone® a series of contributions (feature available from February 2015). The data that it deposits then have "under discussion" status. An article is created on the forum enabling other web users and the members of the governance committee to discuss these data.
The data proposed in this way are therefore left in "under discussion" status for at least three months. Once this period has elapsed, the data are submitted to the governance committee of the Base Carbone® for validation. This committee then decides:
- Either, to leave the data in "discussion" status (discussions underway, pending information from various stakeholders, competitor data also pending, etc.)
- Or, to validate the data with "generic valid" status or "specific valid" status if the data comply with the methodological framework for contributions (furthermore, a quality score and a transparency score will be allocated to the data)
- Or, to assign the data "refused" status if the data do not comply with the methodological framework for contributions
Sometimes, new data will come in to replace already existing valid data. These old values are not deleted, but switch to "archived" status
Certain validated data of the Base Carbone® have not followed this path. This concerns:
- Initial data that was in the Base Carbone® before the implementation of this procedure
- Data deriving from major studies in which ADEME is involved (these data are directly assessed by the Base Carbone® governance committee without passing via the "under discussion" status)
