The study aims to explore the relationship between IFRS S1, S2, and Strategic Managerial Accounting (SMA) practices by building an applied model in an environment where these standards have not yet been implemented. The study focuses on the manufacturing sector in Iraq, as it is the sector most affected by environmental issues. The content analysis methodology was used to extract quantitative indicators from companies’ reports related to sustainability standards. The results showed that the adoption of the Sustainability disclosure Standards (SDS) requires incorporating this information into consolidated and financial disclosure reports. The results of implementing Material Flow Cost Accounting (MFCA) showed that this tool helps reclassify costs between positive (product outputs) and negative (non-product outputs). The analysis demonstrates a complementary relationship between the use of SMA practices and the ability to implement modern disclosure standards, thereby contributing to the generation of quantitative information necessary for their implementation. The study proposes conducting similar studies in vital sectors such as the oil, cement, and food industries to verify the suitability of Strategic Managerial Accounting Practices, such as MFCA, in different production environments and whether the findings obtained in Diyala Company apply to diverse industrial contexts. In light of the theoretical and applied analysis of Strategic Managerial Accounting Practices, and based on the results of implementing MFCA at the Diyala General Company for Electrical Industries, the following conclusions can be drawn: It is clear that the applied accounting system focuses on recording costs in general without giving sufficient importance to environmental or social costs, leading to a clear lack of comprehensive disclosure. Contrary to the requirements of IFRS S1 and S2.
