It covers the full project design document lifecycle: defining the project boundary and GHG sources/sinks/reservoirs, constructing and justifying the baseline scenario, demonstrating additionality through regulatory surplus, barrier, and common practice analysis, systematically assessing and quantifying leakage (activity shifting, market effects, ecological leakage), and building a monitoring plan. The skill includes a comprehensive reference covering ISO 14064-2, Verra VCS, and Gold Standard requirements, a pre-structured MRV document template, and an automated audit tool that checks for compliance gaps before VVB submission. ## Getting Started Add your project data to the workspace — emission inventories, financial models, methodology references, stakeholder records, and any existing project documentation — then activate the *Emission Baseline Verifier* skill. The agent will determine the applicable standard(s), apply the MRV document template, and guide you through each section from project boundary through net emission reductions. The `baseline_leakage_audit` tool can be run at any stage to catch compliance issues early. --- ## Example Conversation Below is an example of how a typical session might unfold when drafting an MRV document for a REDD+ avoided deforestation project under Verra VCS. The agent collects project context, applies the template, and runs compliance validation. > **You:** I need to prepare an MRV project design document for the Cerrado Forest Conservation Project. It's a REDD+ avoided deforestation project in Goiás, Brazil, targeting Verra VCS certification. We're applying methodology VM0015. The crediting period is 30 years starting 2025-01-01. The project area is 12,000 hectares of cerrado woodland. We estimate 45,000 tCO2e/year in avoided emissions. There's a nearby soy farming frontier that may cause some leakage. > > **Agent:** I'll set up the MRV document using the template. This is an AFOLU project under VCS, so I need to address a few additional requirements: > > 1. **Non-permanence risk** — AFOLU projects require a VCS buffer pool contribution. I'll include the risk assessment section. > 2. **Leakage** — You mentioned soy farming frontier pressure. This will likely involve both **activity shifting** (deforestation displaced to adjacent areas) and **market leakage** (reduced agricultural supply from the protected area). Both need quantification. > 3. **VM0015** requires specific baseline deforestation rate analysis using historical remote sensing data. > > Before I populate the template, a few questions: > - What is the historical deforestation rate in the project area and reference region? (needed for VM0015 baseline) > - Do you have emission factors for cerrado biomass (tC/ha above-ground, below-ground, soil)? > - Are there any communities with legal land use rights within the project boundary? > > **You:** Historical deforestation rate is 1.8%/year based on PRODES data 2010–2024. Reference region rate is 2.1%/year. Biomass: 85 tC/ha above-ground, 25 tC/ha below-ground, soil carbon excluded as conservative. No communities with legal rights inside the boundary, but three settlements within 10 km. > > **Agent:** I've created the MRV document at `output/mrv-document.md` with: > > - **Project boundary:** 12,000 ha cerrado woodland, Goiás, Brazil. GHG gases: CO2 (primary), CH4 (fire emissions, included), N2O (fire, excluded as conservative). > - **Baseline emissions:** 1.8%/yr deforestation × 12,000 ha × (85 + 25) tC/ha × 3.67 = ~87,000 tCO2e/yr gross. Discounted to 45,000 tCO2e/yr after project emissions and leakage. > - **Additionality:** Regulatory surplus confirmed (no legal mandate to conserve this specific area), investment barrier documented, common practice analysis shows < 5% of cerrado under voluntary conservation. > - **Leakage assessment:** > - Activity shifting: 15% discount applied (VM0015 default for high frontier pressure) > - Market leakage: 5,400 tCO2e/yr from displaced soy production > - Ecological leakage: Not applicable (no wildlife corridor displacement documented) > - **Buffer pool:** 15% non-permanence risk deduction (political risk + natural disturbance) > > I ran `baseline_leakage_audit` on the draft: > - ✓ Baseline scenario description — present > - ✓ Baseline emission quantification — present > - ✓ Baseline methodology — present (VM0015 referenced) > - ✓ Activity shifting leakage — quantified (15% discount) > - ✓ Market leakage — quantified (5,400 tCO2e/yr) > - ✓ Regulatory surplus test — present > - ✓ Barrier analysis — present > - ✓ Common practice analysis — present > - ⚠ Monitoring QA/QC procedures — needs detail on remote sensing calibration > - ⚠ 8 placeholders remaining (stakeholder consultation, financial model details) > - ⚠ SDG contributions not documented (only required for Gold Standard, but recommended) > > The draft is ready for your review. Shall I expand the monitoring plan section or fill in the financial analysis next? --- ## Excerpt from a Generated MRV Document Below is a representative excerpt from an MRV project design document produced with the skill. --- ### MRV Project Design Document — Cerrado Forest Conservation Project (Excerpt) **Project Proponent:** Cerrado Verde Conservation Ltd. **Location:** Goiás, Brazil (15.2°S, 49.8°W) **Methodology:** VM0015 v1.1 — Avoided Unplanned Deforestation **Crediting Period:** 2025-01-01 to 2054-12-31 (30 years, renewable) --- #### 5. Leakage Assessment ##### 5.1 Leakage Sources Identified | Leakage Type | Applicable | Justification | |--------------|-----------|---------------| | Activity Shifting | Yes | Soy farming frontier within 10 km creates displacement pressure. Historical land-use change analysis shows 68% of deforestation in the reference region is driven by agricultural expansion. | | Market Leakage | Yes | Protecting 12,000 ha reduces potential agricultural output, partially displaced to other areas. Market leakage factor applied per VM0015 §8.3. | | Ecological Leakage | No | No evidence of wildlife corridor displacement. Nearest protected area (Serra Geral) is 45 km away with distinct ecological pressure drivers. | | Upstream Emissions | No | Conservatively excluded. No significant supply chain emissions attributable to the conservation activity. | ##### 5.2 Leakage Quantification | Leakage Source | Quantification | Unit | Method | |----------------|---------------|------|--------| | Activity shifting | 13,050 | tCO2e/yr | VM0015 default: 15% of baseline emissions (87,000 × 0.15). Applied due to high frontier pressure index (> 0.6). | | Market leakage | 5,400 | tCO2e/yr | Displaced soy area × regional emission factor: 600 ha/yr × 9.0 tCO2e/ha (IPCC Tier 2, cerrado conversion to cropland). | ##### 5.3 Total Leakage Emissions (LE) **Total leakage: 18,450 tCO2e/year** > **Note:** Leakage represents 21.2% of gross baseline emissions. This is within the expected range for REDD+ projects in high-pressure frontier regions (VM0015 Table 8: 10–30%). The activity shifting discount is conservative — actual displacement may be lower given the distance to the nearest agricultural frontier (8–12 km). --- *This excerpt is illustrative only. Final content must reflect actual project data and be reviewed by a qualified auditor.* --- ## Validations Performed by the Tool The skill includes one automated validation tool that checks **MRV compliance** of a project design document in markdown format. Below is a summary of what it validates and how to interpret results. ### Tool: `baseline_leakage_audit` Audits the full MRV document for structural completeness and compliance gaps. | Check | Description | |-------|-------------| | **Baseline Scenario** | Verifies presence of: baseline scenario description, baseline emission quantification, baseline methodology/approach, data sources with provenance, and validity period / reassessment schedule. Reports **ERROR** for each missing element (ISO 14064-2 §5.4). | | **Leakage Assessment** | Checks for a leakage section, identifies specific leakage categories (activity shifting, market, ecological, upstream/downstream, displacement), and verifies each identified type is quantified in tCO2e or justified as negligible. Reports **ERROR** if identified leakage lacks quantification (VCS §3.14, ISO 14064-2 §5.6). | | **Leakage Deduction** | Verifies leakage is explicitly deducted in the net emission reduction formula (ER = BE − PE − LE). Reports **WARNING** if leakage is discussed but no deduction is detected. | | **Additionality** | Checks for regulatory surplus test, barrier analysis, common practice analysis, investment/financial analysis, and additionality conclusion. Reports **ERROR** for missing regulatory surplus or conclusion. | | **Approved Methodology** | Detects VCS methodology references (VMxxxx, ACMxxxx, AMSxxxx). Reports **WARNING** if none found. | | **SDG Contributions** | Checks for SDG references. Reports **ERROR** for Gold Standard projects, **WARNING** for others. | | **Project Boundary** | Verifies SSR (sources, sinks, reservoirs) boundary definition and identification of specific GHG gases (CO2, CH4, N2O). Reports **ERROR** if no boundary found. | | **Monitoring Plan** | Checks for monitoring parameters, frequency, QA/QC procedures, and responsibility assignments. Reports **WARNING** for missing elements. | | **Emission Reductions** | Detects the net emission reduction/removal calculation and uncertainty/conservativeness assessment. Reports **WARNING** if missing. | | **Document Completeness** | Detects unfilled placeholders (`[TODO]`, `...`, `{}`) and reports count. | ### Interpreting Results - **RESULT: COMPLIANT** — Baseline, leakage, and additionality checks passed. Document can proceed to VVB review. - **RESULT: REVIEW NEEDED** — Potential gaps detected (missing monitoring details, placeholders, optional elements). Check warnings. - **RESULT: NON-COMPLIANT** — Leakage or baseline issues found. Must be corrected before VVB submission. The tool **does not** replace review by a Validation/Verification Body (VVB): it provides automated pre-screening for structural completeness and leakage accounting integrity. Final compliance with ISO 14064-2, VCS, and Gold Standard must be validated by an accredited VVB. --- Back to [Skill Library](https://rakenne.app/skills/index.md)
