Production and Application for the Removal of Carbon via Biochar (PARC)

As the global Carbon Dioxide Removal (CDR) sector scales, the biochar market faces a critical trilemma: how to mandate uncompromising scientific precision for large-scale industrial facilities, ensure equitable carbon finance access for artisanal smallholder farmers in the Global South, and mathematically guarantee centennial-to-millennial-scale permanence. 

To address this, Gold Standard is introducing the Production and Application for the Removal of Carbon via Biochar (PARC) methodology. Designed exclusively for true net-negative accounting, PARC pioneers a Modular Tiered Architecture that separates feedstock sourcing and end-use applications into distinct, verifiable modules. 

To balance high inclusivity with extreme environmental integrity, the methodology introduces three distinct Compliance Tracks: 

• Track 1: Empowers smallholders using distributed kilns by utilizing highly conservative global default factors and 100% digital MRV smartphone apps, bypassing prohibitive laboratory costs. 
• Track 2: A pragmatic bridge for mid-scale, mobile, or containerized retorts utilizing continuous thermal proxy monitoring. 
• Track 3 : Mandates Continuous Emission Monitoring Systems (CEMS) and strict ISO-accredited laboratory error propagation for large-scale commercial facilities. 

Crucially, the PARC methodology enforces a "Pure CDR Mandate"—explicitly zeroing out the crediting of all counterfactual avoided baseline emissions (e.g., displacing fossil fuels or preventing crop burning). 

Open for consultation alongside the methodology is the Supplementary Information (SI) document, providing the robust macroeconomic sector assessment and the peer-reviewed scientific justification for the methodology's conservative default parameters and lock-in risk exemptions. 

Specific questions from Gold Standard to stakeholders include: 

1. PoA Scale Deviation : 

The methodology proposes a strict deviation from standard rules: capping issuance at 60,000 tCO2e per vintage across the entire Programme of Activities (PoA) boundary, rather than at the individual VPA level. Is this threshold set at a level that effectively ensure operations to graduate to the rigorous direct measurement, without hindering the growth of legitimate smallholder aggregation programs?" 

2. "Pure CDR" Mandate (Zeroing out Avoided Emissions): 

PARC intentionally sets the unadjusted baseline strictly to zero excluding all 'Avoided Emissions' (e.g., preventing open crop burning) to focus solely on the physical removal of pyrogenic carbon. In your view, does this strict exclusion provide the absolute clarity on pure CDR scope?" 

3. Mechanism B Permanence for Unmonitorable Sinks: 

"For highly distributed agricultural soils or biochar encapsulated in concrete, PARC introduces a Fixed Non-Permanence Risk Deduction (an immediate, permanent ex-ante volume cancellation) rather than demanding 100-year physical monitoring covenants. Do buyers and auditors agree this is a more transparent and pragmatic safeguard than attempting to enforce unenforceable century-long tracking?" 

4. Closing the MSW Fossil Loophole via Radiocarbon (14C) Testing: To process Municipal Solid Waste (Track 3), PARC rejects the assumption of '100% mechanical sorting' and strictly mandates continuous Radiocarbon (14C) isotope testing to mathematically isolate biogenic carbon. Does this requirement provide confidence that PARC projects are neutralizing the risk of subsidizing fossil-plastic incineration? 

5. Advancing 1,000-Year Claims via Petrography and Anoxic Vaults: 

"PARC defines specific pathways to unlock 1,000-year durability claims utilizing advanced petrography (Mean Random Reflectance Ro < 2.0% for the Inertinite fraction) and engineered subterranean earth vaults. Does the scientific community agree these specific thresholds establish a robust, commercially testable proxy for millennial-scale carbon removal?
