Several greenhouse gas reporting schemes and obligations require that biogenic CO2 emissions are reported in addition to fossil fuel CO2 emissions. Companies that report under the GHG Protocol and/or that are required to report under the Corporate Sustainability Reporting Directive (CSRD) are requested to report biogenic CO2 emissions separately from other greenhouse gas emissions. In Scope 1 and 2, these emissions are usually counted as zero as they are short-cycle carbon.
The reporting targets have prompted the inclusion of biogenic CO2 emission factors on CO2emissionfactors.co.uk.
In this report we propose Tank-to-Wheel (TTW) Scope 1 and 2 biogenic CO2 emission factors that can be included alongside the Well-to-Tank (WTT) and TTW CO2 emission factors on CO2emissiefactoren.nl.
