Greenhouse Gas (GHG) Accounting & Climate Strategy

Greenhouse Gas (GHG) accounting is not a reporting exercise. It is a structural mapping of organizational exposure across operational, financial, and supply chain systems.

DEISO delivers Scope 1, Scope 2, and Scope 3 emissions accounting aligned with internationally recognized standards, including ISO 14064, ISO 14040/14044, and the GHG Protocol. The objective is not carbon estimation—it is governance-ready, verification-aligned climate intelligence.

When Carbon Accounting Fails

Many organizations quantify emissions but cannot defend them under scrutiny.

Common structural failures include:

• Undefined organizational and operational boundaries
• Inconsistent consolidation methodologies
• Incomplete Scope 3 category mapping
• Double counting across entities and subsidiaries
• Untraceable supplier emission assumptions
• Misaligned emission factors and data sources
• Absence of verification-ready documentation systems

Under regulatory pressure, investor due diligence, or third-party assurance, weak structures fail. Carbon figures without system logic create exposure.

Scope 1–3 Emissions: Structural Mapping Framework

Scope 1 — Direct Emissions

Emissions from owned or controlled sources, including fuel combustion, industrial processes, and operational assets.

Scope 2 — Indirect Energy Emissions

Electricity-related emissions using both location-based and market-based methodologies, supported by supplier-specific data where available.

Scope 3 — Value Chain Emissions

Comprehensive mapping of upstream and downstream emissions across all relevant GHG Protocol categories, including purchased goods, capital goods, logistics, waste, business travel, employee commuting, product use, and end-of-life treatment.

Scope 3 requires system boundary clarity, allocation logic, and in many cases, hybrid Life Cycle Assessment (LCA) integration to ensure defensibility.

What Makes DEISO Different

Many providers rely on spreadsheets, generic emission factors, and narrative-driven reporting. DEISO delivers structured, technically grounded systems.

• Defined organizational and operational boundaries aligned with ISO methodology
• LCA-integrated Scope 3 modeling where required
• Transparent allocation methodologies
• Traceable emission factor selection
• Structured documentation for assurance readiness
• Governance-level reporting alignment

Carbon accounting must integrate with operations and decision-making systems—not remain isolated within reporting functions.

Standards & Framework Alignment

All engagements are aligned with:

• ISO 14064-1 (GHG Quantification & Reporting)
• ISO 14064-3 (Verification & Validation)
• ISO 14040 / 14044 (Life Cycle Assessment)
• GHG Protocol Corporate Standard
• GHG Protocol Scope 3 Standard
• Science-Based Target methodologies where applicable
• Sector-specific regulatory frameworks

Methodological coherence is prioritized through:

• Clearly defined system boundaries
• Transparent data sources and assumptions
• Consistent calculation logic
• Version-controlled data systems
• Verification-ready reporting structures

The objective is defensibility, not presentation.

From Accounting to Climate Strategy

Carbon accounting without transition planning is incomplete. DEISO transforms emissions data into structured climate strategy.

• Emission hotspot identification
• Scenario modeling and sensitivity analysis
• Decarbonization pathway development
• Supplier engagement strategies
• Net-zero alignment frameworks

This enables organizations to move from reporting to actionable climate governance.
