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.

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.
