CDP asks if biogenic CO2 is relevant to us. Do we say yes if we burn biomass?
Yes, if CO2 from biogenic carbon, such as burning biomass or biogas, matters to the people reading your response. Then 7.12.1 asks for the tonnes of CO2, reported separately from Scopes 1, 2 and 3, as the GHG Protocol requires.
The test
"Relevant" means the information users need for their decisions. If biomass or biogas is a real fuel for you, say yes.
What 7.12.1 asks
- Direct CO2 from biogenic carbon, in metric tons CO2, from sources you own or control.
- Indirect biogenic emissions, if you want to report them, go in the comment with quantity and source.
- Do not put CH4 or N2O from burning biomass here. They belong in Scope 1, 2 or 3.
A common slip
Do not treat biomass as a zero emission fuel. CDP says it still produces emissions and should not carry a zero factor. Its CO2 is reported outside the scopes, and its CH4 and N2O inside them.
Example with made-up numbers
- A boiler burns husk. Your fuel record and factor give 900 t of biogenic CO2.
- 7.12: Yes. 7.12.1: enter 900.
- The methane and nitrous oxide from the same boiler, in CO2e, go in Scope 1.
The 900 t is an example, not a husk factor.
What Senseible does here
Senseible records the fuel quantity from invoices and weighbridge slips, so the biomass tonnes behind a separate biogenic CO2 line are traceable.
