What Is VMR0016? Verra Methodology Explained Step by Step

If you develop or evaluate landfill gas projects under the Verified Carbon Standard (VCS), you need to understand VMR0016. Released by Verra on November 21, 2025, VMR0016 Flaring or Use of Landfill Gas (ACM0001 Revision), v1.0, is the current methodology for quantifying emission reductions from capturing and destroying methane at landfill sites. It consolidates and replaces two legacy Clean Development Mechanism (CDM) methodologies, and every active landfill gas project under VCS will eventually operate under its rules.

What Is VMR0016?

VMR0016 is a consolidated methodology under the VCS Program, classified under Sectoral Scopes 1 (Energy) and 13 (Waste Handling and Disposal). It covers the destruction of methane emissions and the displacement of more greenhouse-gas-intensive energy services by capturing landfill gas (LFG) and doing one or more of the following:

• Flaring the captured methane.
• Using the gas to produce electricity or thermal energy.
• Supplying cleaned gas to consumers through natural gas distribution networks, dedicated pipelines, or trucks.

VMR0016 replaces two standalone CDM methodologies that Verra previously recognized: ACM0001 v19.0 (large-scale consolidated methodology for landfill gas) and AMS-III.G v10.0 (small-scale methodology for the same activity). Both will be inactivated under the VCS Program on December 1, 2026.

Who Does VMR0016 Apply To?

The methodology applies to project developers operating landfill gas capture and destruction systems anywhere in the world, provided the project meets the applicability conditions defined in the methodology document. Typical project types include:

• New LFG capture systems installed at landfills with no prior gas collection.
• Enhancements to existing capture systems that increase the volume of methane destroyed.
• Facilities that use captured LFG for electricity generation, direct thermal use, or pipeline injection.

Projects that generate revenue streams beyond carbon credit revenues must demonstrate additionality using VT0009 (Combined Baseline and Additionality Assessment). This is a condition set by the Integrity Council for the Voluntary Carbon Market (ICVCM) for Core Carbon Principles (CCP) compliance.

How VMR0016 Works: Step by Step

1. Confirm Applicability

Before selecting VMR0016, verify that your project activity falls within its scope. The landfill must be a solid waste disposal site, and the project must involve capturing LFG that would otherwise be released to the atmosphere. Review the full applicability conditions in the official VMR0016 document on the Verra website to confirm eligibility.

2. Demonstrate Additionality

VMR0016 requires use of VT0009 (Combined Baseline and Additionality Assessment). This Verra tool provides procedures for investment analysis, barrier analysis, and common practice analysis. It also identifies the baseline scenario. Projects listed on the positive list (adapted from CDM TOOL32) may qualify for automatic additionality, meaning they do not need to complete the full investment or barrier analysis.

3. Define the Baseline Scenario

The baseline assumes that, without the project, methane generated by decomposing waste would be released to the atmosphere. Deductions are made for the fraction of methane that would be oxidized naturally by bacteria in the soil cover of uncovered landfills, and for any methane that would be destroyed by a pre-existing baseline destruction device. Baseline emissions therefore equal the total methane destroyed by eligible project devices, minus these deductions.

4. Quantify Emission Reductions

Emission reductions are calculated as baseline emissions minus project emissions minus leakage. Key parameters include:

• Volume of LFG captured and sent to each destruction device.
• Methane concentration in the captured gas.
• Destruction efficiency of each flare or utilization device.
• Electricity or thermal energy generated and delivered.
• Emission factor for displaced grid electricity, calculated using VT0011 (Electricity Systems Emission Factors).

Project emissions from on-site electricity consumption are determined using VT0010 (Emissions from Electricity Consumption). The global warming potential of methane applied in the calculation must follow the values specified in the VCS Standard.

5. Establish Monitoring

The methodology requires continuous or periodic measurement of gas flow rates, methane concentration, and destruction device operating parameters. VMR0016 also introduces a new reporting parameter for installed electricity generation capacity, which must be included in monitoring reports even though it does not affect credit issuance directly. All monitoring equipment must be calibrated according to manufacturer specifications and applicable standards.

6. Submit for Validation and Verification

Once the project design document is complete and monitoring data has been collected, submit the project for third-party validation and verification through the VCS Program. The validation/verification body (VVB) will assess conformity with VMR0016 and associated Verra tools.

Key Tools Referenced by VMR0016

Unlike its CDM predecessors, VMR0016 relies on Verra-developed tools rather than CDM tools:

• VT0009: Combined Baseline and Additionality Assessment.
• VT0010: Emissions from Electricity Consumption.
• VT0011: Electricity Systems Emission Factors.

These tools replace older CDM equivalents and are designed to align with ICVCM Core Carbon Principles.

Common Mistakes to Avoid

• Using outdated CDM tools. VMR0016 references VT0009, VT0010, and VT0011. Applying the old CDM additionality tool or grid emission factor tool will result in a non-conformity during validation.
• Missing the transition deadline. ACM0001 v19.0 and AMS-III.G v10.0 are inactivated on December 1, 2026. If your project needs registration or crediting period renewal under the old methodology, the request must be submitted by November 30, 2026.
• Ignoring the corrections notice. Verra released corrections to VMR0016 v1.0 on July 13, 2026. All projects must apply these corrections. Using the uncorrected version will cause issues at verification.
• Skipping the positive list check. If your project qualifies under the positive list adapted from CDM TOOL32, you can simplify the additionality demonstration. Failing to check this list means unnecessary analytical work.
• Omitting installed capacity reporting. The new reporting parameter for installed electricity generation capacity is mandatory even though it is for reporting only. Leaving it out of the monitoring report is a common oversight.

What to Do Now

If you are developing a new landfill gas project under the VCS Program, start with VMR0016 v1.0 and the associated corrections released in July 2026. Download the full methodology document and the three referenced tools (VT0009, VT0010, VT0011) from the Verra website.

If you have an active project registered under ACM0001 or AMS-III.G, you may continue using the applied methodology through your current crediting period. At your next crediting period renewal, you will need to transition to VMR0016. Plan for this transition now by reviewing the methodology differences and updating your monitoring plan.

For projects approaching registration, confirm whether the November 30, 2026 deadline for legacy methodology submissions applies to you. If it does, prioritize your registration request. If it does not, proceed directly under VMR0016.

In all cases, consult the official VMR0016 methodology text on the Verra website for the complete set of applicability conditions, equations, and monitoring requirements. This guide provides an orientation, but the binding document is the methodology itself.
