### **Launch of Public Consultation – M-ICR017**

The International Carbon Registry (ICR) has initiated a public consultation for a new methodology under development, further expanding the scope of carbon removal activities covered by the ICR program.

The consultation includes:

[**M-ICR017 – Integrated Direct Air Capture and Microalgae Carbon Removal Methodology**](/documentation/icr-program/public-consultation/methodologies/2026/m-icr017.md)

This methodology introduces an integrated approach to quantify net greenhouse gas removals by combining engineered Direct Air Capture (DAC) technologies with biological carbon fixation through microalgae systems, coupled with long-term carbon storage in durable end-use products.

#### **Scope and objectives**

M-ICR017 focuses on the full carbon removal pathway from atmospheric capture through to final storage. The methodology supports:

* direct removal of CO₂ from the atmosphere using DAC systems,
* biological fixation of carbon via microalgae cultivation,
* conversion of biomass into durable products (e.g. concrete, biochar, soil amendments) with long-term storage, and
* comprehensive lifecycle-based accounting of emissions and removals.

The methodology applies a cradle-to-grave accounting framework, ensuring that all emissions associated with capture, processing, transport, and potential re-emissions are considered, resulting in conservative and transparent quantification of net removals.

The approach integrates engineering-based carbon capture with biological systems and aligns with ISO 14064-2 principles, while introducing a structured framework for hybrid carbon removal activities.

#### **Consultation process**

The public consultation period runs from **27 April 2026 to 27 May 2026**.

ICR invites stakeholders, technical experts, project developers, and validation and verification bodies (VVBs) to review the methodology and submit feedback. Stakeholder input is a critical component in ensuring methodological robustness, environmental integrity, and practical applicability.

A webinar will be jointly organized by ICR and the methodology developer during the consultation period to present the methodology and engage with stakeholders. Further details will be communicated separately.

#### **Next steps**

Following the consultation:

* ICR will consolidate all stakeholder feedback,
* the methodology developer will respond to comments and revise the methodology as appropriate, and
* the methodology will undergo validation by an ICR-approved VVB prior to final review and approval.

#### **Access to consultation documents**

The methodology and consultation form are available on the [ICR Public Consultation page](/documentation/icr-program/public-consultation.md).

#### **Effective status**

This methodology is currently under public consultation and is not yet approved for use under the ICR program.
