Negative emission technologies (NET), e.g. BECCS and DACCS, and their potential for carbon dioxide removal (CDR) cen:proj:80989

Scope

Create a standard for CDR certificate accounting
o Carbon accounting will consider the full process chain from biomass sourcing to permanent storage of
CO2
• Carbon accounting for CCS applications that fall under ETS will be created by CEN-CENELEC (CEN NWIP
Carbon dioxide quantification and verification for CCS). CDRs will be realized by the same process chains as
CO2 storage for application that fall under ETS. Additionally, CDRs will also need to apply to carbon accounting
requirements imposed by CDR methodologies. These CDR methodologies ensure the generation of CDR credits
towards clients of CDR certificates. Alignment between CDR carbon accounting by the CDR methodologies
(such as CRCF or on the voluntary market) and ETS related carbon accounting of CCS will result in
increased standardization of the CCS process chain.
o Context: The permanent CDR (DACCS & BECCS) market is expected to be initiated in the voluntary
carbon market. For companies to trade permanent CDR certificates on the voluntary carbon market,
they have to adhere to a CDR methodology verified by an independent company (such as Verra of Puro
Earth). These methodologies aim to standardize the carbon accounting. To prevent conflict between
these multiple standards and methodologies, it is beneficial to align the carbon accounting requirements
resulting in reduced efforts in measurements or accounting administration. Having a standardized
methodology will enable technology and project developers to trade CDR certificates on the voluntary
carbon market. Additionally, these standards will also enable buyers to make informed and transparent
choices while purchasing CDR certificates. The latter is especially applicable as long as CRCF is not
yet completed.
• Define permanent CDR technologies (DACCS & BECCS).
o This will at a minimum be on the definition of the term. It is to be evaluated if it is beneficial to perform a
technological assessment.
• Measurement and traceability of biogenic CO2
• Set up requirements to the CDR process chain accounting. Consider to refer to other standards. The
requirements will consider the following:
o Contribution to Climate mitigation
o Co-benefits and Trade-offs or potential side effects
o Sustainability
o Social responsibility
o Safety
