What Is ISO 14064?

ISO 14064 is the international standard for:

• Quantifying greenhouse gas emissions

• Designing GHG inventory systems

• Monitoring and reporting emissions

• Preparing for third-party verification

It is commonly used to support:

• ESG disclosures

• Investor reporting

• Supply chain reporting

• Voluntary carbon initiatives

• Corporate sustainability programs

• Regulatory climate requirements

ISO 14064 provides structure where many organizations rely on spreadsheets and assumptions.

What an ISO 14064 Consultant Should Deliver

A qualified ISO 14064 consultant should not simply calculate emissions.

We build governance-driven systems that include:

1. Organizational Boundary Definition

• Equity share vs. operational control approach

• Consolidation methodology

• Documentation of entity inclusion/exclusion

2. Operational Boundary Design

• Scope 1 emissions (direct emissions)

• Scope 2 emissions (energy indirect)

• Scope 3 emissions (value chain impacts)

We help you define what is material and defensible.

3. Emissions Quantification Methodology

• Data source identification

• Activity data mapping

• Emission factor selection

• Calculation methodology documentation

• Uncertainty evaluation

Your inventory must withstand scrutiny from investors and auditors.

4. GHG Inventory Management System

• Data collection controls

• Internal review checkpoints

• Version control of emission factors

• Management review oversight

• Internal audit alignment

We integrate GHG reporting into your management systems — not outside them.

5. Verification Readiness Preparation

• Documentation packages

• Evidence traceability

• Sampling preparation

• Data integrity checks

• Corrective action alignment

We ensure your system can pass independent verification.

Scope 1, Scope 2, and Scope 3 — Structured Approach

Many organizations underestimate the complexity of Scope 3 emissions.

We help you:

• Prioritize categories based on materiality

• Develop defensible estimation methodologies

• Build supplier engagement frameworks

• Improve data quality over time

Scope 3 is not about perfection — it is about controlled improvement.

How ISO 14064 Integrates With Other Standards

If you already maintain a management system, ISO 14064 should integrate — not operate independently.

We regularly integrate ISO 14064 with:

• ISO 14001 Environmental Management Systems

• ISO 9001 Quality Management Systems

• ISO 45001 Occupational Health & Safety

• GRI reporting frameworks

• TCFD and climate-related risk disclosures

• ESG governance structures

Our approach aligns GHG reporting with executive oversight and risk governance.

Common Reasons Organizations Hire an ISO 14064 Consultant

Organizations typically engage us when:

• Preparing ESG or sustainability reports

• Responding to investor climate inquiries

• Addressing supply chain decarbonization demands

• Preparing for voluntary GHG verification

• Building internal carbon accounting systems

• Supporting net-zero commitments

• Preparing for future regulatory climate rules

If your current emissions reporting feels informal, undocumented, or overly reliant on one person — it is time for systemization.

The Risk of Poor GHG Accounting

Improperly structured emissions reporting can result in:

• Greenwashing accusations

• Investor credibility damage

• Inaccurate ESG scoring

• Regulatory exposure

• Failed verification audits

• Misleading internal climate strategy

ISO 14064 provides structure to prevent these risks.

Frequently Asked Questions

Is ISO 14064 certification required?

ISO 14064 itself is not a certification standard in the same way ISO 9001 is. However, GHG inventories can be verified by independent bodies.

Can small companies implement ISO 14064?

Yes. The framework scales. Complexity depends on operations and value chain exposure.

Do we need ISO 14001 first?

No. ISO 14064 can be implemented independently, though integration strengthens governance.

How long does implementation take?

Depending on data maturity, most organizations complete initial system development in 3–6 months.
