Our Approach to Sustainability Reporting and Assurance
This report details our sustainability performance for all businesses, assets, and partnerships that are owned and operated by Tourmaline for the period between January 1 to December 31, 2025, and includes reference to certain actions Tourmaline undertook in both 2025 and 2026. Unless otherwise stated, references to “dollars” or “$” means Canadian dollars. Tourmaline successfully acquired and amalgamated Saguaro Resources Ltd. (“Saguaro”) on June 6, 2025. The performance data included in this report is pro-rated to reflect this business combination, unless otherwise stated. It only reflects performance data for Saguaro after June 6, 2025. We have not adjusted current targets or historical performance to reflect the impact of acquisitions.
Scope
We are committed to transparent, annual reporting on our sustainability performance. Within this report, we are pleased to share comprehensive information on the progress we made in 2025. To support disclosure on material sustainability topics, we have incorporated discussion points and metrics aligned with the Sustainability Accounting Standards Board (SASB) standards, which are now overseen by the IFRS Foundation, using the EM-EP Oil & Gas – Exploration & Production industry classification. The Global Reporting Initiative (GRI) reporting framework has also been used to provide additional industryspecific guidance (GRI 305-2). Our greenhouse gas emissions (GHG) are measured and reported using the GHG Protocol Corporate Accounting and Reporting Standard and Scope 2 Guidance. Climate-related disclosures are informed by recommendations from the International Financial Reporting Standards (IFRS), specifically IFRS S2 Climate-related Disclosures, which incorporates the recommendations from the Task Force on Climate-Related Financial Disclosures (TCFD). While our climate disclosures are guided by IFRS S2, the TCFD framework continues to inform our approach and serves as a useful reference for communicating climate-related governance, strategy, risk management, and metrics and targets.
Standards & Frameworks
At Tourmaline, we track and report relevant data that is important to our stakeholders. To ensure we are sharing highquality information based on advanced data systems, we are constantly improving our processes and controls for data and measurement capture capability. Tourmaline’s GHG Scope 1 and 2 emissions have been externally verified. GHD Limited has provided a reasonable level of assurance on Tourmaline’s 2025 Scope 1 and 2 emissions. This verification was carried out in accordance with the requirements of GHG Protocol and ISO Standard 14064-3. Ernst & Young LLP (“EY”) has provided a limited level of assurance, as defined by Canadian Standards on Assurance Engagements, to report on Tourmaline’s total Scope 1 and 2 GHG emissions for the year ended December 31, 2025.
