Engagement
GHG inventory assurance
Focused testing of Scope 1, 2, and selected Scope 3 categories with activity data trails and emission-factor documentation.
Designed for companies whose climate section carries the highest stakeholder weight. We examine organizational and operational boundaries, sample activity data against invoices and meters, and check emission factors and unit conversions.
Scope 3 categories are included only when named in the engagement letter and supported by primary or supplier data—not by untested spend estimates alone. Fees start from NT$280,000 depending on facilities sampled.
