Carbon Inventories & Credits

Enabling Credible Carbon Measurement & Credits in Livestock Systems

C-Lock Inc. provides corporations with regulator-recognized methane measurement technology that turns livestock emissions data into audit-ready carbon inventories and verified carbon credit opportunities.

Powered by the GreenFeed® system, C-Lock enables organizations to confidently measure, manage, and monetize enteric methane reductions across complex supply chains.

Key Benefits

  • Verified methane measurement for defensible carbon inventories
  • Carbon-credit ready data aligned with leading methodologies
  • Scope 3-ready insights across livestock supply chains
  • ESG-aligned outcomes supporting net-zero commitments

How C-Lock Provides Value

Supply Chain Decarbonization

  • Measure and reduce Scope 3 emissions across supplier networks
  • Establish farm-level methane baselines for procurement standards
  • Track mitigation progress from feed additives (like 3-NOP) or management interventions
  • Create low-emission sourcing and certified programs using verified data

Carbon Revenue & Cost Offset

  • Generate Verra-compliant carbon credits from methane reductions
  • Monetize emissions reductions through voluntary carbon markets
  • Offset mitigation costs (feed additives, technology) with carbon credit revenue
  • Create internal carbon pricing mechanisms for sustainability investments

Brand & Market Differentiation

  • Validate "low-carbon" or "climate-friendly" product claims with independent data
  • Meet retailer sustainability requirements
  • Respond to investor ESG scrutiny with verified emissions data
  • Capture premium pricing for verified low-emission dairy and beef products

Operational Efficiency

  • Identify high-emitting animals or management practices for targeted interventions
  • Optimize feed efficiency while reducing methane (methane often correlates with feed waste)
  • Benchmark genetics performance across facilities, suppliers, or regions
  • Make data-driven decisions on sustainability investments

Regulatory Recognition & Carbon Credit Eligibility

Verra-Approved Methane Measurement for Carbon Markets

GreenFeed® is officially recognized by the Verra Verified Carbon Standard (VCS)—the world’s leading voluntary carbon credit program—as an approved methane measurement system under the VM0041 methodology for enteric methane reduction.

Verra classifies GreenFeed as a static head chamber capable of accurately measuring CH₄ and CO₂ emissions from individual animals, with required repeated measurements to ensure verification-grade reliability. This approval enables corporations to quantify methane reductions with project-level precision, meeting the strict requirements for high-integrity carbon credits.

Key Benefits

  • Verra-approved measurement under VM0041 methodology
  • Verification-grade methane data at the individual animal level
  • Carbon-credit eligible outputs for voluntary markets
  • Low-risk pathway to monetizing methane reductions or meeting internal decarbonization targets

Don't Just Take Our Word For It

Global Endorsements for Emission Inventories

FAO – United Nations Food & Agriculture Organization

In its report Methane Emissions in Livestock and Rice Systems, the FAO identifies GreenFeed as a best-practice, field-deployable tool for individual methane measurement under both confinement and grazing conditions.

  • GreenFeed demonstrated a correlation of r ≈ 0.96 with respiration chambers and minimal bias, confirming equivalence with laboratory gold standards.
  • FAO emphasized GreenFeed’s scalability and cost-effectiveness, making it well-suited for large-scale carbon inventory development and mitigation programs.

Corporate impact: FAO endorsement reinforces GreenFeed’s suitability for enterprise-wide emissions accounting, particularly in geographically distributed livestock supply chains.

USDA-ARS (2024) – GreenFeed Measurement Protocol

The USDA Agricultural Research Service (ARS) published a formal GreenFeed protocol recognizing the system as a “modified open-circuit respiration chamber” for commercial beef and dairy operations.

  • The protocol confirms reliable measurement across methane outputs ranging from 80 to 2000 g/day, consistent with traditional chamber systems.
  • Establishes standardized procedures for repeatable, auditable methane quantification.

Corporate impact: USDA validation supports regulatory-grade carbon inventories and reduces methodological risk in sustainability disclosures and credit programs.

Global Research Alliance & UNFCCC Recognition

The Global Research Alliance on Agricultural Greenhouse Gases (GRA) published a GreenFeed Standard Operating Procedure (2018), later recognized by the UNFCCC as a technical reference for livestock methane monitoring.

  • GRA confirms global adoption and recommends GreenFeed for verifying enteric methane mitigation in support of offset and reporting frameworks.

Corporate impact: Alignment with UNFCCC-referenced methodologies enhances credibility for international ESG reporting and global carbon initiatives.

Practical Benefits for Corporate Carbon Programs

Accurate, Individual-Level Methane Data

GreenFeed measures grams of CH₄ per animal per day, enabling corporations to:

  • Establish defensible methane baselines
  • Quantify mitigation impacts from feed additives or management changes
  • Aggregate data by farm, supplier, or production system for inventory reporting

Carbon Credit & Value Creation

With GreenFeed, corporations can:

  • Implement verified methane mitigation strategies (e.g., 3-NOP)
  • Generate Verra-compliant measurement data
  • Monetize reductions through voluntary carbon markets or internal Scope 3 reduction programs

ESG, Net-Zero & Supply Chain Compliance

GreenFeed data integrates seamlessly into:

  • Scope 1 and Scope 3 livestock emissions inventories
  • Sustainability reporting frameworks (CDP, GRI, TCFD)
  • Low-emission sourcing and ESG-aligned procurement programs
