How Landfill Gas Projects Earn Carbon Credits Under VMR0016: From Project Design to Issuance

Landfill gas is one of the largest anthropogenic sources of methane, a greenhouse gas roughly 80 times more potent than CO₂ over a 20-year horizon. Capturing and destroying that methane is one of the most direct ways to generate carbon credits on the voluntary market. VMR0016 Flaring or Use of Landfill Gas, v1.0, published by Verra under the Verified Carbon Standard (VCS) Program, is the methodology that governs how these projects quantify emission reductions and convert them into tradable Verified Carbon Units (VCUs).

This guide walks through the full project cycle: what VMR0016 covers, who can use it, and every stage from project design to credit issuance.

What Is VMR0016 and What Does It Replace?

VMR0016 is a consolidated methodology for landfill gas capture projects under Verra’s VCS Program. It replaces two earlier Clean Development Mechanism (CDM) methodologies: ACM0001 (Flaring or use of landfill gas) and AMS-III.G (Landfill methane recovery). Both predecessors will be inactivated as standalone methodologies under the VCS Program on December 1, 2026.

The methodology falls under Sectoral Scope 13 (Waste handling and disposal) and carries a mitigation outcome label of Reductions. It was developed to align with the Core Carbon Principles (CCPs) established by the Integrity Council for the Voluntary Carbon Market (ICVCM) and received CCP approval in August 2026.

What VMR0016 Covers

VMR0016 applies to project activities that capture landfill gas and use it in one or more of the following ways:

• Flaring the captured methane (thermal destruction without energy recovery)
• Generating electricity or thermal energy from the landfill gas
• Supplying processed landfill gas to consumers through natural gas distribution networks, dedicated pipelines, or trucks

The methodology is globally applicable. There are no geographic restrictions on where a qualifying landfill may be located.

Who Can Use This Methodology

Any project developer operating or planning a landfill gas collection and destruction system at a solid waste disposal site can apply VMR0016, provided the project meets the applicability conditions defined in the methodology document. Projects that generate revenue streams beyond carbon credits must demonstrate additionality using VT0009 (Verra’s Combined Baseline and Additionality Assessment tool), showing that carbon credit revenue is a decisive factor in the project’s financial viability.

Projects that qualify under the methodology’s positive list (adapted from CDM TOOL32) may be eligible for automatic additionality determination, simplifying this step.

Step-by-Step: From Project Design to Credit Issuance

Step 1: Select the Methodology and Prepare the Project Description

The project developer confirms that VMR0016 is the correct methodology for the planned activity. Using the latest VCS Project Description template available on the Verra website, the developer drafts a complete project description document (PD). This document must detail:

• The project boundary and the landfill site characteristics
• The baseline scenario (what would happen without the project)
• The project scenario (how gas will be captured and used or destroyed)
• The quantification approach for baseline emissions, project emissions, and leakage
• The additionality demonstration, using VT0009 or the positive list
• The monitoring plan, including parameters, measurement frequency, and equipment

The developer must also reference VT0010 (Tool for calculating emissions from electricity consumption) if the project consumes grid electricity.

Step 2: Create a Verra Registry Account and List the Project

The developer establishes an account in the Verra Registry and submits the draft project description for pipeline listing. Once listed, the project enters a mandatory 30-day public comment period. Any stakeholder can submit comments, which the developer must address before finalizing the PD.

Step 3: Validation by an Approved VVB

After the public comment period closes, the developer engages an approved Validation/Verification Body (VVB). The VVB conducts an independent assessment to determine whether the project meets all VCS rules and requirements, including conformance with VMR0016 and the additionality procedure specified in the methodology. Validation typically involves a desk review, a site visit, and interviews with project personnel.

The developer finalizes the project description based on VVB findings and submits the project for registration with Verra.

Step 4: Verra Review and Registration

Verra applies a risk-based approach (RBA) to review registered projects. This review goes beyond the VVB audit and examines risk factors that could affect environmental integrity. If the project passes review, Verra registers it in the VCS Program.

Step 5: Monitoring

Once the project is operational, the developer monitors greenhouse gas reductions according to the monitoring plan defined in the PD. For landfill gas projects under VMR0016, key monitored parameters typically include:

• Volume of landfill gas captured
• Methane concentration in the captured gas
• Volume of gas flared or used for energy generation
• Electricity generated and consumed
• Installed capacity of electricity generation equipment (reporting-only parameter introduced by VMR0016)

Monitoring data is compiled into a VCS Monitoring Report using the official template.

Step 6: Verification by an Approved VVB

An approved VVB (which may or may not be the same body that performed validation) verifies the monitoring report and the emission reductions claimed for the monitoring period. The VVB confirms that data collection followed the monitoring plan and that calculations conform to the methodology.

Step 7: VCU Issuance

After Verra approves the verification, the developer submits an issuance request. Verra then issues Verified Carbon Units (VCUs) into the developer’s registry account. Each VCU represents one metric tonne of CO₂ equivalent reduced. These VCUs can be sold on the voluntary carbon market or retired to meet corporate climate commitments.

Common Mistakes to Avoid

• Using an inactivated methodology. Projects that intend to register under ACM0001 v19.0 or AMS-III.G v10.0 must submit their registration request by November 30, 2026. After December 1, 2026, new projects must use VMR0016.
• Skipping the additionality demonstration. Projects with multiple revenue streams cannot rely on the positive list alone. VT0009 requires a financial analysis showing that carbon revenue is the deciding factor.
• Incomplete monitoring plans. VMR0016 introduced installed capacity as a reporting-only parameter. Omitting it from the monitoring plan will cause issues during verification.
• Choosing a VVB too late. Engaging a Validation/Verification Body early in project design helps identify gaps in the PD before the public comment period, reducing the risk of delays during validation.
• Ignoring the corrections document. Verra published corrections to VMR0016 v1.0 in July 2026. Developers must consult the latest version of the methodology and any published corrections before finalizing their project documents.

What to Do Now

If you are developing or planning a landfill gas project and intend to earn carbon credits under the VCS Program:

1. Download the full text of VMR0016 v1.0 and its July 2026 corrections from the Verra website.
2. Review the applicability conditions to confirm your project qualifies.
3. Download the latest VCS Project Description template and begin drafting your PD.
4. Identify and contact an approved VVB early in the process.
5. If your project was previously under ACM0001 or AMS-III.G, check whether you need to transition to VMR0016 at your next crediting period renewal.

The official methodology document and supporting tools (VT0009, VT0010) are available at verra.org. For projects already in the pipeline under the predecessor methodologies, the registration deadline of November 30, 2026 is firm.
