The CCS+ carbon accounting infrastructure provides methodologies, tools and modules for industrial carbon management to quantify emission reductions and removals through CCS, long-term storage through CCU, and emission removals through CDR activities.

This guide compares procedures developed within the CCS+ carbon accounting infrastructure to the requirements formulated under the Paris Agreement´s Articles 6.2 and 6.4. It focusses on additionality testing, baseline setting, and monitoring, reporting and verification (MRV).

The CCS+ procedures to test additionality and regulate MRV are well aligned with the high quality requirements of Article 6. A combination of the CCS+ framework and other existing approaches provides good opportunities to align the baseline setting procedures that are specific to Article 6.

This guide provides practical input to tackle Article 6-specific key methodological challenges, including approaches for addressing the risk of carbon lock-in and the risk of non-permanent storage.
