Verra VM0042 — Improved Agricultural Land Management
VM0042 (Improved Agricultural Land Management) is Verra's methodology for crediting greenhouse-gas benefits — including soil organic carbon — from practice changes such as reduced tillage, cover cropping, and nutrient management. As of July 2026 the current version is v2.2, and it supports three quantification routes: measure-and-model, measure-and-remeasure, and default IPCC emission factors.
Current status (as of July 2026)
As of July 2026, VM0042 v2.2 is the current version. A major revision was in consultation around February–March 2026, accompanied by a new Soil Sampling and Analysis Handbook and alignment with the VCS Program v5.
- Version: v2.2 current; major revision under consultation (Feb–Mar 2026).
- Sampling: new Soil Sampling and Analysis Handbook informs measurement design.
- Programme: alignment with VCS Program v5.

The three quantification routes
VM0042 lets projects quantify soil carbon change three ways, trading cost against accuracy: measure-and-model, measure-and-remeasure, and default IPCC emission factors.
Measure-and-model
Measure SOC at intervals and use a calibrated process model (RothC, CENTURY or DNDC) to estimate stock change between and beyond sampling events. Balances cost with accuracy for larger or heterogeneous areas.
Best for: Scalable projects with good management data
Measure-and-remeasure
Directly measure SOC stocks at the start and re-measure on a defined cycle, quantifying change empirically. Highest measurement burden but the most direct evidence of change.
Best for: Sites where dense, repeated sampling is practical
Default IPCC emission factors
Apply default IPCC stock-change factors for defined practice and climate combinations. Lowest cost and accuracy; typically the most conservative crediting.
Best for: Screening or contexts lacking site-specific data
Frequently asked questions
What is Verra VM0042 used for?+
It credits GHG benefits, including SOC gains, from improved agricultural land management practices on cropland and grassland. Confirm current requirements against Verra's published version before relying on them.
Is VM0042 being revised?+
A major revision was in consultation around February–March 2026, alongside a new Soil Sampling and Analysis Handbook and alignment with the VCS Program v5. Details are evolving as of July 2026 — verify the live version before designing a project.
What are the three VM0042 quantification approaches?+
Measure-and-model (using RothC, CENTURY or DNDC), measure-and-remeasure (direct repeated sampling), and default IPCC emission factors. Each trades cost against accuracy.
