Responsible sourcing program Internal Audit Contractor welfare We strive to adhere to responsible business partnering principles in our relationships, guided by our Procurement Policy, due diligence and evaluation programs as outlined in our Supplier and Partner Code of Ethics and contractual agreements. ADNOC’s Code of Ethics enforces fair labor practices, anti-corruption measures, environmental protection and responsible use of confidential information. Our active suppliers and partners have signed this code, with dedicated ethics and compliance channels available for reporting concerns. In addition, we screen and monitor our suppliers and partners to monitor compliance with safety, environmental, health and labor standards. By integrating responsible sourcing with our In-Country Value (ICV) program and health, safety and environment (HSE) governance, ADNOC seeks to embed sustainability and ethics in our procurement program. This approach helps us create long-term economic, environmental and social value for ADNOC, our suppliers and the communities we serve. In 2024, ADNOC launched its Responsible Sourcing Program (RSP) to boost transparency and promote sustainable procurement. Further, the Program helps ensure our procured products and services contribute to ADNOC’s sustainability agenda. Achieving the RSP’s goals are centered around four main pillars: 1. Collaborate with suppliers 2. Manage ESG risks across the value chain 3. Leverage technology to better manage ESG risks and opportunities 4. Promote sustainability leading practices across the value chain As part of the program, we reviewed and updated our procurement policies to align with current sustainability standards. We conducted ESG pre-assessments with 30 strategic suppliers, organized supplier forums and stakeholder sessions to foster open dialogue and to collaborate on future strategies that could enhance sustainability across ADNOC’s The Internal Audit function, an internal part of ADNOC, operates under the oversight of the ADNOC Audit Committee, a subcommittee of the Board. Our Internal Audit follows a centralized assurance approach, including all operated companies in a comprehensive annual risk-based audit planning process. Strategic alignment of the audit function is maintained through five-year plans refreshed annually, along with a rolling three-year risk-based internal audit plan reviewed yearly. These plans are also revisited in response to significant changes in the business landscape or risk profile. Our internal audit priorities are determined through the outcomes of a structured risk assessment process, aligned with Abu Dhabi Accountability Authority (ADAA) regulations and the Institute of Internal Auditors’ (IIA) Global Internal Audit Standards (GIAS) and informed by stakeholder input, ADNOC’s approach to responsible sourcing is closely tied to our commitment to the health, safety and wellbeing of contractors across our operations.

The objective is to improve contractor welfare conditions in their site locations, including accommodation, recreation, catering, medical and other facilities.

To build internal capability, 90% of our procurement employees received training in responsible sourcing and governance, empowering them to make procurement decisions that support ADNOC’s Sustainability Strategy. We developed a customized sustainable procurement training program which is scheduled for roll out in 2025. We seek to continue enhancing the RSP by improving the measurement, monitoring and management of environmental and social performance in our supply chain. Key focus areas include tailored supplier engagement, enhanced ESG metric monitoring and robust performance evaluation mechanisms. including ESG considerations.
