### **Launch of Public Consultation – M-ICR019**

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

The consultation includes:

[**M-ICR019 – Avoidance of methane emissions through excavating and composting of partially decayed municipal solid waste (MSW) at closed solid waste disposal sites**](https://documentation.carbonregistry.com/documentation/icr-program/public-consultation/methodologies/2026/m-icr019)

This methodology, developed by [**Blue Planet Environmental Solutions Pte Ltd**](https://www.carbonregistry.com/directory/45173bd0-6344-412f-9df9-8a4cbe8dd387), provides an approach to quantify greenhouse gas emission reductions from the excavation and aerobic treatment of partially decayed MSW already deposited at closed or legacy solid waste disposal sites.

#### **Scope and objectives**

M-ICR019 is based on, and adapted from, CDM methodology AMS-III.AF. It retains the core activity logic of AMS-III.AF while removing the small-scale threshold and introducing additional safeguards for large-scale application under the ICR program.

The methodology supports:

* methane emission reductions from closed or legacy solid waste disposal sites,
* excavation and separation of partially decayed MSW,
* controlled composting or aerobic stabilization of the biodegradable fraction,
* conservative baseline quantification using First-Order Decay landfill gas modelling, and
* strengthened monitoring, sampling, QA/QC and leakage assessment.

In the absence of the project activity, the biodegradable fraction of the waste would continue to decompose anaerobically and generate methane emissions. Emission reductions are calculated as the difference between baseline emissions and the sum of project emissions and any applicable leakage.

#### **Consultation process**

The public consultation period runs from **31 August 2026 to 1 October 2026**.

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

A webinar will be organized 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 proceed through the next steps of the ICR methodology approval process.

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

The methodology and consultation form are available on the ICR Public Consultation page:

Comments may be submitted through the consultation form:

#### **Effective status**

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