GAB-Accredited Verification Body
GSustain is one of only two Qatar-based verification bodies accredited by the Global Accreditation Bureau (GAB) under ISO 14065. We provide independent GHG verification and validation services for organizations across Qatar and the GCC — from corporate GHG inventories to carbon credit projects under the Global Carbon Council programme. Our verification engagements are conducted with full impartiality, technical rigour, and alignment with ISO 14064-3:2019.
Scope of Verification
Independent, accreditation-backed verification across the full spectrum of GHG reporting and carbon credit programmes.
Organizational carbon footprints across Scope 1, 2, and 3 emissions verified against international standards.
Emission reduction and removal project claims verified for credibility and additionality.
Validation and verification under the Global Carbon Council (GCC) programme. CORSIA-eligible credits.
Lifecycle emissions for products and services, verified for accuracy and compliance.
Corporate sustainability claims independently verified for stakeholder confidence.
Declarations of net-zero and carbon neutrality independently assessed for defensibility.

Expert Answers
GHG verification is an independent, third-party assessment of an organization's greenhouse gas emissions data against ISO 14064 standards. In Qatar, GHG verification is increasingly required for organizations reporting under the National Climate Change Action Plan, participating in the Global Carbon Council carbon credit programme, exporting goods subject to the EU Carbon Border Adjustment Mechanism (CBAM), or making public net-zero and carbon neutrality claims. GSustain is one of only two Qatar-based verification bodies accredited by the Global Accreditation Bureau (GAB) under ISO 14065.
GHG verification costs in Qatar typically range from QAR 35,000 to QAR 150,000+ depending on organizational complexity, number of facilities, scope of emissions (Scope 1, 2, and/or 3), and whether the engagement covers an organizational inventory (ISO 14064-1) or a carbon credit project (ISO 14064-2). GSustain provides fixed-fee proposals after an initial scoping discussion, with no hidden costs. Contact us for a tailored quote.
ISO 14064-1 specifies requirements for designing, developing, and reporting organization-level GHG inventories (corporate carbon footprints). ISO 14064-2 specifies requirements for quantifying, monitoring, and reporting GHG emission reductions and removal enhancements at the project level (e.g., renewable energy or carbon capture projects). ISO 14064-3 specifies requirements for the verification and validation of GHG statements — it is the standard that verification bodies like GSustain follow when conducting assessments. Together, they form a complete framework for GHG accounting and assurance.
Organizations that need GHG verification in Qatar include: companies reporting under Qatar's NDC commitments and National Climate Change Action Plan; operators in Qatar Energy industrial cities (Ras Laffan, Mesaieed) with environmental reporting obligations; project developers seeking carbon credits through the Global Carbon Council; exporters facing EU CBAM requirements; companies pursuing Science-Based Targets (SBTi); organizations making public net-zero or carbon neutrality claims; and financial institutions requiring verified emissions data for climate-related disclosures (TCFD/ISSB).
A typical GHG verification engagement in Qatar takes 4-6 weeks from engagement agreement to verification statement issuance. The timeline depends on organizational complexity, number of emission sources, data readiness, and whether site visits are required. Simple single-facility verifications may complete in 3 weeks, while complex multi-site Scope 1-2-3 verifications may take 8 weeks. GSustain offers expedited timelines where data maturity allows.
