What VM0042 v2.2 Actually Covers
In one sentence
VM0042 provides the rules for estimating and verifying greenhouse gas reductions and carbon removals that result from changing how agricultural land is managed, with a particular focus on increasing soil organic carbon (SOC).

The Five ALM Practice Categories
Think of these five categories as the five levers a farmer can pull to reduce emissions or build soil carbon. A project can use just one lever or combine several for larger impact.
VM0042 covers any agricultural practice change that increases SOC or reduces net GHG emissions. These fall into five categories:
| Category | Examples | Primary GHG Benefit |
|---|---|---|
| (a) Fertilizer Management | Reduce synthetic N, switch to slow-release, add compost/manure | ↓ N₂O, ↑ SOC |
| (b) Water Management | Drip irrigation, alternate wetting & drying in rice | ↓ CH₄ (rice), ↑ SOC |
| (c) Tillage / Residue | No-till, reduced tillage, residue retention (stop burning) | ↑ SOC, ↓ N₂O |
| (d) Crop Planting & Harvest | Cover crops, agroforestry, improved crop rotations | ↑ SOC, carbon removal |
| (e) Grazing Practices | Rotational grazing, reduce stocking density | ↑ SOC, ↓ CH₄ |
📍 Real-World Example, Kenya
A cooperative of 500 smallholder farmers in western Kenya has been practising continuous maize monocropping with conventional tillage. They want to switch to no-till + maize-bean intercropping + residue retention.
This touches categories (c) (no-till, residue retention) and (d) (intercropping). VM0042 provides the rulebook for measuring how much additional carbon their soils store and how many credits they can earn.
🍽️ Analogy: Three Ways to Know if Your Recipe Worked
The three quantification approaches are like three ways to verify a cooking recipe. Approach 1 uses a sophisticated oven thermometer and a food science model to predict doneness. Approach 2 uses a physical taste-test at the start and end. Approach 3 uses the timing on the recipe box, simple but less precise. Higher precision = more confidence = more credits surviving the uncertainty deduction.
Three Ways to Quantify Carbon
VM0042 offers three quantification approaches depending on available resources and data:
Measure & Model
Use a biogeochemical model calibrated with soil measurements
Measure & Re-Measure
Directly measure SOC at project and control sites over time
Default Factors
Use IPCC emission factors, simplest but less precise
Key Takeaways
- 1VM0042 v2.2 (Improved Agricultural Land Management) is globally applicable, covering cropland and grassland under AFOLU Sectoral Scope 14
- 2Five ALM practice categories: fertilizer management, water management, tillage/residue, crop planting/harvest, and grazing practices
- 3Three quantification approaches are available: Measure and Model (Approach 1), Measure and Re-Measure (Approach 2), and Default Factors (Approach 3)
- 4Projects can combine multiple practice categories for larger carbon benefits - stacking is encouraged
- 5The methodology generates both emission reduction VCUs and carbon removal VCUs using the Project Method for additionality and baseline
