INDEPENDENT PRACTITIONER’S LIMITED ASSURANCE REPORT
To the management of Canadian Western Bank (the “Bank”) We have undertaken a limited assurance engagement on certain key performance indicators of the Bank, included in the accompanying Sustainability Report (the “Report”) (“subject matter information”) and as described in the table below, for the period ended October 31, 2022.
Subject matter information
Units
Applicable criteria
• The World Resources Institute / World Business Council for Sustainable Development Greenhouse Gas Protocol –Corporate Accounting and Reporting Standard Revised Edition; and • The GHG Protocol Scope 2 Guidance, an amendment to the GHG Protocol Corporate Standard.
Scope 1 GHG emissions
2,339 tonnes CO 2 e
Scope 2 GHG emissions (location- based and market -based)
3,614 tonnes CO 2 e
Other than as described in the preceding paragraph, we did not perform assurance procedures on the remaining information included in the Report, and accordingly, we do not express a conclusion on this information.
Management’s responsibility Management is responsible for the preparation and presentation of the subject matter information in accordance with the applicable criteria. There are no mandatory requirements for the preparation, publication or presentation of greenhouse gas (“GHG”) performance metrics. As such, the Bank applies the World Resources Institute/World Business Council for Sustainable Development’s Greenhouse Gas Protocol Corporate Accounting and Reporting Standard, and the GHG Protocol Scope 2 Guidance, an amendment to the GHG Protocol Corporate Standard, for GHG emissions reporting (collectively the “applicable criteria”). Management is responsible for determining the appropriateness of the use of the applicable criteria. Management is also responsible for determining the Bank’s objectives in respect of sustainability performance and reporting, including the identification of stakeholders and material issues. Management is also responsible for such internal control as management determines necessary to enable the preparation and presentation of the subject matter information that is free from material misstatement, whether due to fraud or error. Practitioner’s responsibilities Our responsibility is to express a limited assurance conclusion on the subject matter information based on evidence we have obtained. We conducted our limited assurance engagement in accordance with International Standards on Assurance Engagements (ISAE) 3410 Assurance Engagements on Greenhouse Gas Statements . This standard requires that we plan and perform our engagement to obtain limited assurance about whether based on the procedures performed and evidence obtained, any matter(s) has come to our attention to cause us to believe that the subject matter information is materially misstated. The procedures performed in a limited assurance engagement vary in nature and timing from and are less in extent than for a reasonable assurance engagement. Consequently, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had a reasonable assurance engagement been performed. Accordingly, it is not a guarantee that a limited assurance engagement conducted in accordance with this standard will always detect a matter that causes the practitioner to believe that the subject matter information is materially misstated. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the decisions of users of the report.
