Transitioning from recognised carbon standard frameworks to the Paris Agreement mechanism
The recognised carbon standard frameworks, established under the Kyoto Protocol, has issued over 2 billion Certified Emission Reductions (CERs) from more than 7,800 projects. With the Paris Agreement's Article 6.4 Mechanism now operational following COP29 in Baku, recognised carbon standard frameworks methodologies are transitioning. The Article 6.4 Supervisory Body approved the transition framework, allowing existing recognised carbon standard frameworks methodologies to be used under A6.4ER crediting, critical for developers seeking Internationally Transferred Mitigation Outcomes (ITMOs) with corresponding adjustments.

Global South Focus
Plan Vivo
Plan Vivo Standard
Community-based AFOLU, smallholder agroforestry, landscapes
Plan Vivo is built specifically for community-based and smallholder projects in the Global South. Founded in 1994 at the University of Edinburgh, it pioneered community forest and agroforestry carbon before VCS existed. The standard places equitable benefit sharing, food security, and community land rights at the centre of its requirements. Plan Vivo certificates (PVCs) are uniquely oriented toward landscape-scale approaches with participatory monitoring systems rather than full MRV infrastructure.
Key Methodologies
- Plan Vivo Agroforestry, Smallholder tree planting and shade-grown systems
- Plan Vivo Community REDD, Village-level avoided deforestation
- Plan Vivo Soil Carbon, Smallholder agricultural intensification
- Plan Vivo Peatland Restoration, Tropical and boreal rewetting
- Plan Vivo Integrated Landscape, Multi-activity nested programmes
Project Categories
Methodology categories we cover.
Carbon project methodologies are sector-specific. Each category has its own additionality tests, baseline constructions, monitoring requirements, and permanence rules. Our team works across the full set of methodology categories active in African markets.
Agriculture, Forestry & Land Use
The largest category by credit volume. AFOLU methodologies cover avoided deforestation (REDD+), improved forest management, afforestation and reforestation, wetland restoration, and agricultural land management. African projects dominate REDD+ issuance globally. Supacare advises on VM0007, VM0009, VM0015, VM0047, Plan Vivo community frameworks and the emerging jurisdictional REDD+ architecture under Article 6.2.
Key Technical Considerations
- Permanence buffer pools and non-permanence risk tools
- Leakage belt delineation (activity shifting vs market effects)
- Reference region and historical baseline construction
- FPIC documentation and benefit-sharing agreements
- Nested project-to-jurisdictional transitions
Renewable Energy & Efficiency
Renewable energy and energy efficiency methodologies issue credits against a grid emission factor baseline. Africa's rapidly declining grid factors (as renewable penetration increases) are compressing available emission reductions, making additionality demonstration increasingly critical. Clean cooking and off-grid energy projects, including ACM0002, AMS-I.D. and Gold Standard TPDDTEC, remain highly viable across sub-Saharan Africa.
Key Technical Considerations
- Marginal vs average grid emission factor choice
- Suppressed demand baseline for off-grid contexts
- Technology longevity and monitored lifetime credits
- Stove performance testing (WBT, CCT, KPT protocols)
- Fuel displacement monitoring in WASH + cookstove bundles
Blue Carbon & Coastal Ecosystems
Blue carbon refers to the carbon stored in coastal and marine ecosystems, mangroves, seagrasses and tidal wetlands. These ecosystems sequester carbon at rates 3–5× higher per hectare than terrestrial forests and hold millennia of accumulated stocks in their soils. VM0033 (Verra) and the Gold Standard Blue Carbon framework provide the current crediting architecture. East Africa's Kenyan and Tanzanian mangrove coastlines are among the world's most productive blue carbon systems.
Key Technical Considerations
- Soil organic carbon sampling protocols (0–100cm core)
- Tidal hydrological baseline modelling
- High belowground-to-aboveground biomass ratios
- Sediment subsidence and sea-level rise permanence risks
- Community tenure and coastal rights documentation
Clean Cookstoves & Household Devices
Clean cooking methodologies issue credits against the counterfactual of open-fire cooking with unsustainably harvested biomass. With 600 million households in Africa still cooking on open fires, this is one of the continent's largest carbon opportunity categories. Gold Standard TPDDTEC and Verra AMS-II.G are the primary frameworks. Supacare supports developers from stove testing through to monitor verification and Fairtrade premium integration.
Key Technical Considerations
- Net calorific value and thermal efficiency testing
- Non-renewable biomass fraction (fNRB) calculation
- Kitchen performance test (KPT) sampling design
- Default values vs measured emission factors
- Gold Standard SDG impact evidence requirements
Industrial Processes & Transport
Industrial and transport methodologies address sectors with high abatement costs. HFC-23 destruction, refrigerant management, cement kiln efficiency and industrial fuel switching are among the most established. African industrial projects have historically been underrepresented in voluntary carbon markets, but emerging cement, steel and transport decarbonisation investments are creating new project pipelines. recognised carbon standard frameworks ACM0010 and A6.4 industrial frameworks are the primary reference standards.
Key Technical Considerations
- Baseline technology and fuel mix documentation
- Process data metering and continuous emissions monitoring
- Global warming potential (GWP) selection for industrial gases
- Product output normalisation (clinker factor for cement)
- Industrial leakage and production shifting risks
Waste Management & Methane Avoidance
Methane avoidance methodologies offer high credit volumes because methane's GWP100 is 28× that of CO₂, meaning avoided methane from landfill, livestock or wastewater generates credits at multiples of the underlying physical gas. African municipalities are expanding landfill gas capture projects. Livestock methane from East Africa's large pastoral sectors represents a significant underexploited pipeline. ACR composting and Verra ACM0002 are primary frameworks.
Key Technical Considerations
- Landfill gas generation model calibration (LandGEM, IPCC Tier 2)
- Methane oxidation factor for managed landfills
- Livestock enteric fermentation vs manure management separation
- Wastewater characterisation and COD removal efficiency
- Compost quality certification and avoided methane calculation
Our Service
Methodology review.
A methodology review is an independent technical assessment of how a project has applied its chosen carbon crediting methodology, conducted before or during VVB validation. It is the most effective risk mitigation tool available to project developers, and the one most frequently skipped.
Supacare's methodology review practice has supported projects registered under VCS, Gold Standard, Plan Vivo and recognised carbon standard frameworks across nine African countries. Our reviews identify the corrective action requests (CARs) and clarification requests (CLs) before the VVB does, protecting project timelines and credit issuance schedules.
Pre-Validation Methodology Review
Most CommonComprehensive technical review of PDD and methodology application before submission to a VVB. Identifies material gaps and argumentation weaknesses that would trigger CARs during validation.
Typical duration: 4–8 weeks
Mid-Validation CARs & CLs Support
RemediationTargeted support when a project is already in validation and has received corrective action requests or clarification requests from the VVB. We draft defensible technical responses and coordinate with the project developer.
Typical duration: 2–4 weeks
Verification Readiness Assessment
Annual CyclePre-verification audit of monitoring data, measurement records and internal quality control documentation. Ensures the project's monitoring report is complete and its data can withstand VVB verification scrutiny.
Typical duration: 2–6 weeks
Independent Technical Review (ITR)
Lender-GradeLender or investor-commissioned independent technical review of a project's methodology, quantification model and VVB findings, typically required for project finance transactions or carbon credit offtake agreements.
Typical duration: 6–12 weeks
Our Methodology Review Process
Document & Scope Review
We begin with a structured review of the project description document (PDD), methodology selection rationale, and any prior VVB correspondence. We map all mandatory provisions from the applicable methodology and assess whether the project's scope, boundary and accounting approach are defensible.
Deliverable
Methodology Selection Report + Gap Register
Additionality Analysis
Additionality is the single most contested element in carbon credit validation. We conduct an independent assessment of the project's additionality argumentation, regulatory surplus, common practice, investment analysis and barrier tests, identifying weaknesses before VVB engagement. For REDD+ projects this includes reference region definition and FREL construction review.
Deliverable
Additionality Assessment Memorandum
Baseline & Quantification Audit
We audit the baseline scenario construction and emission reduction calculation model. This includes verifying input data sources, emission factor choices, uncertainty analysis and conservativeness adjustments. For AFOLU projects we review the carbon pool selection rationale and above/below ground biomass allometric model choices.
Deliverable
Quantification Model Review + Conservative Parameter Analysis
MRV System Design Review
The monitoring, reporting and verification (MRV) plan determines whether the project can generate credible annual verification data. We assess whether the proposed monitoring protocols, sampling design, data management systems and internal quality control procedures are adequate to withstand VVB scrutiny and meet programme requirements.
Deliverable
MRV Design Assessment + Monitoring Protocol Recommendations
VVB Readiness Report
We consolidate findings into a VVB Readiness Report, a structured document that identifies every outstanding issue that would likely generate a validation finding, corrective action request (CAR) or clarification request (CL) from a VVB. Issues are categorised by severity and assigned recommended remediation actions with priority ranking.
Deliverable
VVB Readiness Report + Remediation Roadmap
VVB Liaison Support
Once validation commences, we provide ongoing support through the VVB review process, drafting responses to CARs and CLs, coordinating technical clarifications, and advising on validation desk review and site visit preparation. Our goal is to reduce validation cycle time and eliminate findings that could jeopardise credit issuance.

Validation & Verification Bodies
Understanding the VVB ecosystem.
Validation and Verification Bodies (VVBs) are the independent, accredited third parties that validate project documents against programme requirements and verify actual emission reductions before credit issuance. Selecting the right VVB, and engaging them at the right stage, is one of the most consequential project development decisions a developer makes.

VVB Selection Guide
What to evaluate before appointing a VVB.
Standard Accreditation
Confirm the VVB holds current accreditation from the programme body for your specific standard and project scope. Accreditations lapse, always verify the current list on the programme body's website.
Sector Competence
VVBs must demonstrate auditor competence in your project type. A VVB accredited for general VCS may lack the sector-specific auditor qualifications required for REDD+ or blue carbon. Request CVs of the proposed audit team.
Timeline & Capacity
VVB pipelines can be 6–18 months full. Engage your preferred VVB early, before finalising your project document, to secure a validation slot and align their review schedule with your credit issuance targets.
Independence Requirements
VVBs cannot validate projects they have provided development support on. If your consultant and VVB are related entities, you face a conflict of interest finding that will halt validation. Maintain clear separation from project inception.
Supacare assists clients in preparing VVB tender documents, evaluating proposals and managing the VVB relationship throughout the validation and verification cycle, from pre-engagement technical readiness assessment through to final credit issuance sign-off.
