ICR has launched public consultations for a new methodology.

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

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.

Effective status

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