Our first DAC + Storage methodology, aligned with the Absolute Carbon Standard (ACS), is now available for public comment. The methodology comprises three modules: Direct Air Capture and Pipeline Transport, Sequestration in Saline Aquifer, and Electricity.
The draft is open for public comment until June 12, 2025, and we welcome feedback from across the carbon removal community. Comments can be submitted directly on the document or emailed to consultation@absoluteclimate.com. All feedback will be reviewed and addressed publicly by the Absolute Climate team.
Why This Methodology Matters
This DAC + Storage methodology is designed to be fully compliant with the Absolute Carbon Standard. It’s been developed using consistent, objective technical criteria to ensure that credits generated under it are comparable not only to other DAC and storage projects but across all carbon removal pathways.
Unlike more prescriptive approaches, this methodology allows project developers to meet key requirements in their own way, designing MRV approaches that reflect the unique characteristics of their technology and projects.
Over several months, the methodology has been shaped with input and technical review from experts across the CDR ecosystem, including:
- Academics
- NGOs
- Validation and Verification Bodies (VVBs)
- Registries
- Project Developers
- Storage operators
We’d like to give a special thanks to David LaGreca, Tim Hanson, Mike Leitch, and Alicia Summers for the time and energy they put into their reviews.
Raising the Bar for Carbon Removal
As the market for high-quality carbon removal grows, it’s critical that methodologies are not just technically sound, but also transparent, comparable, and rooted in real climate impact.
By aligning with ACS, this DAC + Storage methodology supports a higher-integrity market by ensuring credit claims reflect real climate results, not just compliance with process.
The draft methodology is available for public review here.
We encourage all stakeholders to contribute feedback and help shape a stronger foundation for carbon removal.
