Incorporating​
​​
-
Data accuracy — We test calculations, methodologies and sampling to confirm that reported figures are free from material error and trace back to source.
​
-
Completeness — We assess whether all material topics, scopes and entities are covered, and whether omissions are justified and disclosed.
​
-
Reliability — We evaluate the robustness of data collection, controls and governance, including roles, documentation, and change management.
​
-
Consistency — We check for methodological consistency period-to-period (and explain changes when they occur) so trends are comparable.
​
-
Alignment with standards — We assess conformance with ESRS/CSRD (Europe), the IFRS/ISSB baseline (S1/S2) including SASB-informed metrics, and legacy frameworks such as GRI and TCFD-recommended content now reflected in IFRS S2. Finance+2IFRS+2

Risk identification — We test whether material ESG risks and dependencies are identified, measured and linked to strategy and controls.
​
-
Opportunity identification — We highlight value-creation levers (efficiency, innovation, financing, market access) surfaced through assurance work.
​

Stakeholder engagement — We review the design and evidence of engagement processes and how feedback informs priorities and disclosures.
