ESG & GHG Assurance Services
Validate Your Sustainability Claims
with Independent Assurance
We offer comprehensive ESG and GHG assurance services to build stakeholder confidence through independent verification of your ESG and sustainability disclosures and GHG inventories. As a licensed assurance service provider, we deliver high-quality evaluations aligned with globally recognized standards, enhancing transparency and strengthening investor trust.
Why ESG & GHG Assurance Matters
Stakeholders demand proof, not promises.
Without independent assurance, even accurate sustainability data faces skepticism from investors, regulators, and customers scrutinizing greenwashing risks. Unverified claims expose organizations to reputational damage and missed financing opportunities, while independently assured data builds investor confidence, ensures regulatory compliance, and creates competitive differentiation.
Our Approach
Our assurance methodology combines technical expertise with international standards, delivering
independent evaluations that strengthen credibility and stakeholder trust.

Got Questions?
Frequently asked questions
What is the correct standard to comply with for GHG reporting?
The most widely recognized standard for GHG reporting is the GHG Protocol (Corporate Accounting and Reporting Standard) and ISO 14064-1 & 2, which provides methodologies for quantification and reporting of greenhouse gas emissions, reductions, removals and removal enhancements. ISO 14067- Carbon footprint of products, Quantification of the carbon footprint of a product (CFP) will assist in the understanding and action to increase GHG removals and reduce GHG emissions throughout the life cycle of a product. ISO 14064-3 is the International Standard for validation/ verification of GHG assertions (GHG Inventories, projects, etc.).
Organizations also align with frameworks like TCFD, CDP, and GRI depending on stakeholder expectations and disclosure requirements.
Why should we get independent assurance if it’s not required by clients or stakeholders?
Independent assurance demonstrates proactive commitment to transparency and builds credibility before requirements emerge. It strengthens stakeholder trust, improves ESG ratings, strengthens your position for sustainable financing opportunities, mitigates greenwashing risks, and positions your organization ahead of anticipated regulatory mandates. Voluntary assurance signals leadership and differentiates you from competitors making unverified claims.
What does level of assurance mean for our stakeholders and compliance obligations?
Limited assurance provides moderate confidence through less extensive procedures (similar to a review), suitable for voluntary disclosures and initial assurance engagements.
Reasonable assurance provides high confidence through comprehensive testing (similar to financial audit), often required for ESG-linked financing, regulatory compliance, or investor-grade disclosures. The level chosen depends on stakeholder expectations, materiality, and strategic objectives.
