Recognize revenue monthly

Suppliers that work with Isometric can get credits issued monthly. Isometric's Certify platform makes verification fast, getting you credits—and cashflow—in weeks, not years.*

A rigorous protocol that works for you

The DAC protocol requires robust greenhouse gas accounting and storage monitoring to ensure credits are issued only when a tonne of carbon dioxide has been durably removed from the atmosphere—creating confidence for buyers and suppliers. 

What’s in the protocol

Energy use accounting

Accurately calculating the emissions associated with energy usage is an important part of determining how much carbon dioxide a project actually removes from the atmosphere. DAC projects that rely on grid electricity must account for the emissions from the energy used to run their operations. 

Our industry-leading energy use accounting requirements recognize the realities of the power procurement market today (including the need for continued expansion of low-carbon generation, and the lack of tracking systems for hourly matching), while maintaining pragmatic guardrails to support the responsible procurement of clean energy:

  • Robust rules to ensure additionality and physical deliverability of energy
  • Options to utilize Renewable Energy Certificates (RECs), Energy Attribution Certificate (EACs) or Power Purchase Agreements (PPAs) to procure low-carbon energy
  • Phased approach to move towards hourly matching as hourly RECs/EACs become available in most energy markets and DAC projects scale in parallel

Isometric co-hosted a workshop on these topics with more than 50 industry leaders, ensuring alignment with DAC buyers and suppliers.

Unlike any other protocol on the market, these requirements are also aligned with key accreditations and emerging carbon dioxide removal policy, including the 45V guidance in the USA and the European Union’s Carbon Removals and Carbon Farming (CRCF) regulation.

Storage

Carbon dioxide from DAC can be stored using various approaches that ensure removal will be durable. By offering multiple storage modules compatible with DAC, Isometric ensures suppliers have options suitable to their local region (for example, subsurface injection may not be available in all locations), and that each option is appropriately monitored to ensure any reversal risk or uncertainty in storage is accounted for.

Isometric’s protocol can verify projects where carbon dioxide is stored in:

  • Geologic storage (including saline aquifers, and mineralization in mafic and ultramafic formations)
  • Storage in carbonated materials via mineralization in a reactor
  • Storage in built materials such as concrete

Isometric’s modular approach makes it easy to understand the requirements for storage in different contexts and allows Isometric to regularly update storage options based on the latest scientific research relevant to reversal risk and uncertainty, which other protocols do not robustly assess.

Greenhouse gas accounting

Quantifying the net negativity of DAC projects is key to ensuring a high quality bar for credits.

The Isometric protocol has clear guidelines for the robust quantification of net negativity. Our accounting framework quantifies direct process emissions and life cycle assessment (LCA) emissions from transportation, energy use, and embodied emissions, including key areas for DAC:

  • Thorough guidance on the allocation of embodied emissions from shared infrastructure
  • Conservative approach to amortization of embodied emissions for equipment utilized throughout a project’s lifetime across multiple batches of removals
  • Robust requirements for accounting for uncertainty in net removals

No other protocol on the market has such comprehensive requirements that align with accreditation and regulatory standards, and give buyers confidence in the quality of their credits.

Life Cycle Analysis

Make verification painless

Data for monitoring storage and quantifying LCA emissions is complex. Calculating total carbon removals per project can be daunting.

Isometric Certify – and its easy to use tools – take the guesswork out of calculating net removals, making verification quick.

Submit easily

Any supplier or software provider can submit data via the platform, saving your team time and increasing the accuracy of your reporting.

Verify quickly

The platform helps verifiers complete robust audits, quickly—meaning suppliers can get credits issued within a month of data submission.

Scale simply

Whether you have a pilot or large site, Certify scales with you. Adding additional sites is straightforward and doesn’t create extra work.

“Carbon removals don’t get delivered to a loading dock, and that means trusted verification is critical.

We’re really excited about Isometric’s scientific rigor, registry business model that increases integrity, and a huge step towards even more transparency in delivering carbon removal.”
