ESG reporting assurance audit
Independent limited or reasonable assurance over selected ESG metrics and narrative claims against the framework your report cites.
Who it is for
Listed companies, groups preparing exchange sustainability filings, and exporters whose buyers or lenders require an independent assurance conclusion on ESG figures. Ideal when internal sustainability and finance teams already produce a draft report and can assign data owners for each metric in scope.
Result you receive
A written assurance conclusion stating the level of assurance (limited or reasonable), the criteria applied (for example GRI topic disclosures or ISSB-aligned climate notes), the period covered, and any qualifications. On request we present findings to the audit committee.
Scope — included
- Scoping memo naming metrics, entities, sites, and assurance level
- Evidence intake, sampling plans, and recalculation of selected KPIs
- Site inquiries at agreed facilities in Taiwan
- Draft findings schedule and management response window
- Final assurance conclusion letter in English (Chinese cover letter available)
Scope — excluded
- Drafting or ghostwriting the ESG report itself
- Management consulting on strategy or net-zero roadmaps
- Legal opinions on regulatory compliance
- Assurance over metrics added after the engagement letter without a change order
