Overview

ISO 14064 Greenhouse Gas Verification and Validation

ISO 14064 is the globally recognized standard for measuring, reporting, and verifying greenhouse gas (GHG) emissions. Closely aligned with the GHG Protocol, it provides a transparent and consistent framework for organizations to quantify emissions and demonstrate climate action at both organizational and project levels. By adopting this framework, businesses ensure their emissions data and reduction claims are accurate, comparable, and credible, supporting international climate reporting and sustainability goals.
IRQS strengthens organizational credibility through independent verification and validation under ISO 14064-3:2019. Our services confirm that GHG inventories and reduction initiatives comply with global standards while ensuring climate projects, such as carbon credits and offset programs, meet defined environmental and performance criteria. With impartial assurance, organizations can confidently disclose emissions, verify reductions, and build trust with regulators, investors, and stakeholders, positioning themselves as leaders in global sustainability.

SCOPE OF WORK

Comprehensive verification and validation of greenhouse gas data, reductions and sustainability initiatives.

Organizational GHG Verification

Assess your organization's greenhouse gas inventories in line with ISO 14064-1 and the GHG Protocol to ensure data accuracy and transparency.

Emission Reduction Validation

Project-Level Validation

Verify GHG reduction or removal projects based on ISO 14064-2, ensuring compliance, credibility, and measurable climate impact.

Carbon Credit Verification

Conduct an independent review of carbon offset programs and credited emission reductions to confirm reliability and integrity.

Performance Assessment

Validate project outcomes and assess long-term sustainability performance to demonstrate accountability and continuous improvement.

Frequently Asked Questions

Your ISO 14064 GHG Emissions Verification and Validation Questions—Answered

ISO 14064 Assurance involves independent verification of an organisation's greenhouse-gas (GHG) emissions inventory and/or reduction projects against the ISO 14064 standard series (including parts 1, 2 & 3). It provides stakeholders with confidence that your GHG assertions are credible, accurate and transparent.

To demonstrate robustness and integrity of your GHG emissions data and reporting. To enhance credibility with regulators, investors, customers and global supply-chain partners. To align with mandatory or voluntary GHG reporting frameworks, help manage carbon-risk and support sustainability credentials.

No. Assurance is a verification/validation activity to confirm your GHG inventory or reductions are in line with the ISO 14064-series requirements, not a certification that you are "ISO 14064-certified." The standard defines quantification, reporting and verification.

ISO 14064-1: Organisational level – quantification and reporting of GHG emissions and removals. ISO 14064-2: Project level – quantification, monitoring and reporting of emission reductions or removal enhancements. ISO 14064-3: Validation and verification of GHG assertions (either organisational or project).

Typically: Review of your GHG inventory boundary, methodology, data sources and controls; On-site or remote audit of data collection, emission calculations and systems; Evaluation of your GHG management system against ISO-14064 principles (completeness, accuracy, consistency, transparency); Independent Assurance Statement detailing scope, methodology, level of assurance and findings; Recommendations for strengthening your GHG reporting and improvement actions.

We provide engagements consistent with international practice: Limited assurance: Reasonable confidence, less intensive testing. Reasonable assurance: Higher confidence through more rigorous evidence, broader scope and deeper sampling.

The timeline depends on: organisation size, complexity of GHG inventory (Scopes 1, 2, 3), number of sites/locations, data maturity and quality. As a guideline, engagements often range from 4 to 10 weeks, once preparatory data is ready.

You would need: GHG inventory (Scopes 1, 2 and if applicable Scope 3) and reduction/removal project data; Emission sources, activity data, emission factors, assumptions and records; Supporting evidence (meter readings, invoices, process logs, transport data, waste flows); Documentation of GHG management system: policies, procedures, roles, data controls; Previous GHG statements or baseline data, if any.

Yes. With increasing requirements for credible GHG reporting from regulators, investors, customers and supply-chains, independent assurance to ISO 14064 provides a recognised level of transparency and trust, aiding disclosure and reducing risk of "green-washing."

You will receive: An Assurance Statement signed by IRQS confirming scope, standard used, level of assurance, boundary, methodology and conclusions; A report summarising findings, observations, any non-conformities or improvement opportunities; Documentation of verification work performed, for your internal audit trail and stakeholder communication.

Submit your company details, baseline GHG data, number of sites/locations, inventory scopes and whether you require project-level or organisational-level verification. IRQS will review, define the scope, and provide a tailored proposal and timeline.

No. As a certification/assurance body, IRQS maintains independence and provides only verification/assurance. We do not offer implementation or consultancy of GHG inventories, data collection systems or emission reduction programmes.
