Build Trust in Your Sustainability Reporting

As sustainability reporting becomes increasingly important to investors, regulators, lenders, customers, and other stakeholders, organizations need confidence that their sustainability information is accurate, complete, and decision-useful. Our Sustainability Assurance Services provide independent assurance over sustainability disclosures, greenhouse gas (GHG) emissions, and other environmental, social, and governance (ESG) information to enhance credibility, transparency, and stakeholder confidence.

At P&A Grant Thornton, we combine deep sustainability, assurance, and industry expertise to help organizations navigate evolving reporting requirements and stakeholder expectations. Our approach is aligned with internationally recognized assurance standards and leading sustainability reporting frameworks, including PFRS Sustainability Disclosure Standards (PFRS S1 and PFRS S2). 

Our Sustainability Assurance Service

We provide independent assurance over sustainability reports and ESG disclosures to help organizations demonstrate the reliability of their sustainability information.

  • Climate-related disclosures prepared in accordance with PFRS S2 Climate-related Disclosures
  • SEC sustainability reporting requirements
  • Integrated reports and non-financial reports

Organizations increasingly face scrutiny regarding the accuracy and reliability of their carbon emissions reporting. We provide independent assurance over greenhouse gas inventories and emissions disclosures, covering emissions from the organization’s own operations (Scope 1), purchased energy (Scope 2), and relevant value chain activities (Scope 3), based on globally recognized methodologies and assurance standards. Our work may include reviewing reporting boundaries, assessing data collection processes and controls, testing activity data against supporting records, evaluating emission factors and calculation methodologies, and considering the completeness and consistency of disclosures. This helps organizations strengthen data quality, improve governance over climate-related information, and provide stakeholders with greater confidence in reported emissions.

With the adoption of sustainability disclosure requirements globally and increasing sustainability reporting expectations in the Philippines, organizations need robust reporting processes and governance frameworks.

Our services include assurance and pre-assurance assessments covering assessment and assurance over:

  • Sustainability-related risks and opportunities
  • Governance disclosures
  • Strategy disclosures
