Carbon dioxide removal (CDR) is key to fighting global warming and keeping the temperature increase below 1.5°C compared to pre-industrial levels. Yet, to make sure that CDR solutions can be counted towards this goal, they need to be verifiable, which requires the development of standards to quantify their impact. This is what the field of monitoring, reporting, and verification, short MRV, is aiming to do.
Climeworks strives for the highest quality of its CDR service, therefore placing the topic of MRV at the center of our development. We want to bring measurability and accountability to CDR, leading the CDR ecosystem to the highest level of integrity.
We have therefore partnered with Carbfix and DNV to develop the world’s first full-chain certification methodology dedicated to CDR via direct air capture and storage (DAC+S). The full-chain methodology covers two modular methodologies focusing on 1) DAC, and 2) storage through permanent underground mineralization. It has been validated by the independent quality and assurance leader DNV, and can now be applied to a DAC+S project such as Orca to third-party verify the CDR produced by this project. As a result, Climeworks delivered its very first third-party verified CDR services to its customers in 2022.
Certification means quality assurance for the invisible qualities of a service or product.
Much like a certification can identify which apples in the grocery store were grown organically, certification in carbon markets is about showing the otherwise imperceivable quality and integrity of CDR to the market and customers. Certification is the result of successful third-party verification that a removal was produced according to a validated methodology and meets a stated standard. Many certification labels exist, each signifying different quality standards and methodologies used to evaluate the product. The certification is only as meaningful as the rigor and integrity of the standard and methodology it stands for.
In the case of CDR, certification means that a third party has verified the removals were produced according to a validated methodology and meet the stated standard. As an example, the CDR services performed at Climeworks’ Orca plant are third-party verified by DNV, based on the methodology that was developed together with Carbfix and which covers all three steps associated with DAC+S.
In the case of DAC+S, all three steps of capturing, transporting, and storing the CO₂ need to be covered by a full-chain methodology to enable third-party verification.
Take a look at the different steps needed to certify CDR:
1. Certification standards
3. Project Design Description/ Document (PDD)
5. Certified CDR
The methodology developed by Climeworks and Carbfix covers two modular methodologies:
The full-chain methodology can now be used to verify the CDR produced by a DAC+S project, such as Orca, where the CO₂ is captured using Climeworks' DAC technology, and transported to the injection site where it is stored using Carbfix's rapid underground mineralization method.
The methodologies can be applied to verify the CDR production of different DAC+S projects, provided that they fulfill the following requirements:
Climeworks is proud to contribute to the standardization and scale-up of high-quality, permanent removals with a DAC+S methodology that is:
