Criterion A.4 - Other GHG included

The Bilan Carbone® method aims above all to reflect physical reality. It therefore takes into account GHG emissions as soon as the level of scientific knowledge allows. In addition to the emissions conventionally assessed, the Bilan Carbone® also offers the possibility of quantifying:

• GHGs governed by other international treaties (e.g. CFCs, nitrogen oxides NOx)
• water vapour and contrails emitted by aircraft in the stratosphere

However, we are aware that these emissions may be incidental (relative to the overall volume of GHG emissions) in the business approaches of certain candidate tools. This is why this criterion is optional.

Pedagogical guidance on accounting for non-Kyoto GHGs

In order to help users understand the importance of considering all greenhouse gases in a carbon accounting exercise, it is important to present them to users, explaining the differences in impact and the types of activity that may be concerned.

This can help users better understand the issues specific to their sector and work on their decarbonisation strategy accordingly.

Criterion

Optional	Criterion A.4 - Other greenhouse gases included
Question	Does the candidate tool allow the integration of other greenhouse gases (such as CFCs or water vapour emissions from aircraft in the stratosphere)?
Answer	Yes, the tool allows non-Kyoto GHGs to be taken into account and these are presented in the resources Yes, the tool allows non-Kyoto GHGs to be taken into account No, the tool does not allow non-Kyoto GHGs to be taken into account, but with justification No, the tool does not allow non-Kyoto GHGs to be taken into account
Implementation guidance	Search the user guide, methodological guide and/or user manual for sections on the greenhouse gases included in the methodology Check whether the tool allows the use of emission factors that account for contrails, or whether it offers all the GWPs present in the Base Empreinte®.
