Geo Energy Resources Limited - Sustainability Report 2025

CLIMATE RELATED DISCLOSURE Geo Energy is committed to addressing climate change and aligning our operations with global e!orts to limit the rise in global temperatures. Recognising the energy consumption and greenhouse gas (GHG) emissions associated with our activities, we seek to minimise our environmental footprint through compliance with relevant environmental regulations1 and by identifying feasible operational improvements. Climate change presents both physical and transition risks to our business. These include acute and chronic physical risk to our business such as extreme heat, flooding, and long-term shifts in weather patterns, as well as evolving regulatory and market challenges, including carbon pricing. In line with the SGX requirements and the recommendations of the Task Force on Climate-related Financial Disclosure (TCFD), we have conducted a climate risk assessment to better understand manage these risks. As global sustainability reporting standards continue to evolve, we are transitioning to the IFRS S2 Climate-related Disclosures, which builds in the TCFD framework2. We acknowledge that climaterelated risks and opportunities change over time, with certain risks materialising over longer horizons due to regulatory developments, technological change, and the long-term nature of physical climate 1 These include the UU No. 32 Tahun 2009 (PPLH), Permen LH No. 3 Tahun 2014 (PROPER), UU No. 7 Tahun 2004 Sumber Daya Air, UU No. 18 Tahun 2008, amongst others. 2 The TCFD was o"cially disbanded in October 2023 and its responsibilities were taken over by the International Sustainability Standards Board (ISSB) under the IFRS Foundation. However, TCFD’s framework remains the foundation of ISSB’s IFRS S2 (Climate-Related Disclosures). The ISSB fully incorporated TCFD’s recommendations into IFRS S2, meaning that companies already aligned with TCFD should not see significant changes in reporting structure. 3 These include assessing climate-related revenue exposure, capital and operational expenditure impacts, carbon pricing exposure, asset impairment, and depreciation risks. Analysing revenue loss due to physical climate risks, risk-adjusted return on investment, and insurance cost changes of the business under di!erent climate scenarios could help us understand and quantify the financial risks and opportunities associated with climate change, enabling informed decision-making and strategic planning. impacts. This underscores the importance of regularly reviewing and updating our strategies. We have conducted a qualitative assessment to account for changes in asset coverage and will continue to refine our climaterelated analysis. Going forward, we plan to incorporate quantitative financial metrics3 to more robustly assess the potential impacts of climate-related risks and opportunities on our business. Further information on our governance structure, strategy, risk management approach and metrics for managing climate-related risks is set out on pages 11 to 14 of this report. Our approach is supported by a dedicated governance structure comprising the Board, relevant Board committees, and the Enterprise Risk Management (ERM) Working Group. These bodies oversee the identification, assessment, and management of climate-related risks, helping to ensure that our business remains resilient and aligned with our longterm sustainability objectives. Climate Scenario Analysis In our 2025 climate risk assessment, a scenario analysis was conducted based on the parameters outlined in Figure 2. BEK and STT were disposed during the year and have been excluded from this assessment. Figure 2.
