This chapter covers rules of the road: what facilities, feedstocks, technologies, and end uses qualify under VM0044. Quantitative permanence factors live in the Permanence note. Facts prefer the v1.1 PDF plus v1.2 public announcements; confirm against the live v1.2 PDF on Verra’s methodology page before submission.
Active rule set
| Item | Status | Source |
|---|---|---|
| Active methodology | VM0044 v1.2 since 27 Jun 2025 | methodology page |
| What v1.2 added | Investment analysis (step 3) under VT0008; Errata & Clarifications; tool version refs | revision announcement |
| v2.0 | Consultation only (Jul–Aug 2026) — not active | consultation |
Verra’s public one-liner: quantifies removals from waste biomass → biochar at new facilities; soil (crop/grassland) and non-soil (e.g., biochar-amended concrete) (methodology page).
Facility newness — greenfield gate
VM0044 v1.1 states the project must install and operate a new (greenfield) biochar production facility(ies) (v1.1 PDF).
| Implication | Detail |
|---|---|
| Existing / retrofit plants | Out of scope under current active framing until v2.0 expands eligibility |
| v2.0 draft | Explicitly proposes expansion to existing facilities (consultation) |
| Contrast Puro | Puro Edition 2025 allows New / Retrofit / Charcoal Repurpose baselines — see Puro Biochar Methodology Edition 2025 |
| Contrast Isometric | Project-specific; not framed as Verra-style greenfield lock — Isometric Biochar Protocol |
For US producers with an already-operating kiln: Verra v1.2 may be a non-starter until v2.0 is approved and adopted — watch the consultation outcome.
Thermochemical scope
| Eligible | Excluded | Source |
|---|---|---|
| Pyrolysis, gasification, biomass boilers (terms used interchangeably for this methodology) | Torrefaction and hydrothermal carbonization | v1.1 §4 — excluded because solids are not significantly more persistent than feedstock (Woolf et al. 2021) |
Health & safety program protecting workers from airborne pollutants is required (v1.1 applicability).
High-tech vs low-tech (four-condition gate)
High technology facilities must meet all of the following (v1.1 definitions, adapted from EBC Production Guidelines):
| # | Condition |
|---|---|
| (a) | Pyrolytic GHGs recovered or combusted — not allowed to escape to atmosphere |
| (b) | ≥ 70% of pyrolysis heat energy used (accounting for heat-transfer inefficiencies) |
| (c) | Pollution controls (e.g., thermal oxidizer) meeting local / national / international emission thresholds (strictest where overlapping) |
| (d) | Production temperature measured and reported |
Fail any condition → low technology production facility (different quantification / monitoring defaults). See Verra VM0044 Permanence and Quantification and Verra VM0044 Project Cycle and MRV.
Non-soil applications are restricted to high-tech biochar only (v1.1 applicability condition 11).
v2.0 consultation flags “detailed criteria for high-technology biochar production facilities” as a revision theme (consultation).
Feedstock — waste biomass only
Core tests (must all hold)
From v1.1 §4:
- Purely biogenic waste biomass — not purpose-grown
- Otherwise left to decay or combusted for purposes other than energy production (Appendix 2 demonstration procedures)
- Not imported from other countries
- Meets Table 1 sustainability criteria for its sourcing category
Table 1 categories (non-exhaustive examples)
| Category | Example themes (v1.1 Table 1) | Notable safeguards |
|---|---|---|
| Agricultural waste biomass | Prunings; straw/leaves/stalks/husk/pomace; fruit/veg residues | Field residues: document no decline in soil C / productivity or baseline open burning; else remove ≤ 50% of residues |
| Food processing residues | Wash/peel/centrifuge residues; expired food; coffee/tea/cocoa/tobacco processing | Residue production per output must not increase to chase biochar |
| Forestry & wood processing | Off-cuts, sawdust, mill by-products; sustainable forest sources | Forest-sourced wood must not drive deforestation/degradation |
| Recycling economy | Urban/rural green waste; biosolids; paper mill sludge | Contaminant thresholds per IBI/EBC |
| Aquaculture plants | Seaweed/algae waste; aquatic invasive (Plantae) | No purposeful introduction of invasives for feedstock |
| Animal manure | Swine, cattle, horse, poultry wastes | By-products of husbandry |
| High-carbon fly ash (HCFA) | Bioenergy cogeneration by-product | ≤ 5% of annual waste biomass throughput; affirmative extraction tech; no fossil makeup for diverted calories; meet IBI |
Mixed feedstocks must still meet IBI Biochar Testing Guidelines or EBC Production Guidelines (v1.1).
Transport of feedstock / biochar
- Non-road (ships/boats/other) allowed up to 200 km
- Distances > 200 km must use road vehicles per CDM Tool 12 framing (v1.1)
Mineral additives
Lime, rock minerals, ash ≤ 10% dry mass without extra proof; above 10% requires lab evidence against IBI/EBC contaminant thresholds (v1.1).
Appendix 2 — waste demonstration
Credible evidence of baseline fate (decay / non-energy combustion): government records, disposal facility records, production records; else literature / surveys of similar industries (v1.1 §6 / App. 2 themes). This is a frequent project failure mode called out by practitioner checklists — treat as validation-critical, not deferrable.
v2.0 proposes expanding eligible feedstocks (invasive species; other new non-purpose-grown streams) (consultation).
End-use eligibility
Timing
Biochar must be utilized in soil or non-soil applications within one year of production (v1.1 condition 9) — decay math is calibrated to 100-year permanence from application, not from multi-year stockpiles.
Soil applications
| Rule | Detail (v1.1) |
|---|---|
| Eligible land | Cropland, grassland, vegetated urban soils, forest — not wetlands |
| Placement | Surface or subsurface |
| Surface rule | Must mix with compost, manure, or anaerobic digestate |
| Subsurface | May be pure or mixed |
| Contaminants | IBI Testing Guidelines or EBC Production Guidelines (or relevant national regs) |
| Chemistry gate | Molar H:Corg ≤ 0.7 |
Contrast Isometric soil module: H/Corg < 0.5 and O/Corg < 0.2 (soil module) — tighter aromaticity gate. See Isometric Modules Soil Built Burial.
Non-soil applications
| Rule | Detail (v1.1) |
|---|---|
| Examples | Cement, asphalt, other long-lived products |
| Tech restriction | High-tech only |
| Carbon content | Biochar ≥ 50% C dry weight |
| Longevity proof | Lab results, peer-reviewed papers, or third-party product assessment including lifetime |
| End-of-life | Must demonstrate biochar in the product is not combusted at end of life |
| Activated carbon | Conditions 14–15 bar biochar “processed into activated carbon” and non-soil uses that lose >50% of the carbon (same text in v1.1 and v1.2; v1.2 PDF pp. 8, 14) — Biochar vs Activated Carbon |
Isometric’s dedicated built-environment module adds Ro-based 1000y math and demolition/abrasion reversal modeling — different architecture than Verra’s non-soil PR_de path.
Additionality
| Version | Approach | Source |
|---|---|---|
| v1.1 | Standardized activity method / positive list (activity penetration) + regulatory surplus | v1.1 §7 |
| v1.2 | Adds mandatory investment analysis (step 3) following VT0008 Additionality Assessment, v1.0 — ICVCM Core Carbon Principles alignment | revision announcement |
| v2.0 draft | Replace positive list with project method additionality | consultation |
Practical: v1.2 projects must budget for investment analysis documentation, not only the activity-penetration / positive-list narrative.
Baseline framing
Baseline: continuation of pre-project waste handling where waste biomass would be left to decay or combusted for non-energy purposes (v1.1). Default net baseline emission avoidance at sourcing stage treated conservatively as zero in the methodology’s BESS framing (v1.1 §8.1.1) — removal claim centers on durable biochar C, not methane avoidance stacking.

US / ag design notes (no invented Prairie facts)
| Design choice | VM0044 implication |
|---|---|
| New kiln vs retrofit | Greenfield required under current active rules |
| Ag residues from fields | Soil-C / productivity documentation or ≤50% residue removal |
| Compost / manure “matrix” pathways | Aligns with surface-application mixing rule |
| Concrete / asphalt offtake | High-tech + ≥50% C + longevity evidence |
| Want existing facility credited | Watch v2.0; consider Puro Biochar Methodology Edition 2025 or Isometric Biochar Protocol in parallel diligence |
