Materiality-Based Approach and Sustainability Commitments

Halliburton's sustainability strategy is built upon our material environmental, social, and governance (ESG) topics. We continue to engage in open, frank dialogue with our stakeholders to ensure we are focused on the right priorities. In 2022, we reviewed our materiality assessment through engagement with investors, customers, workforce, community organizations, and suppliers to help identify and prioritize ESG topics that are material to the Company. We took a three-tiered approach to conduct the assessment, with key stakeholders involved through different levels of engagement. Along with priorities from prior years, we expanded previously aggregated topics, such as climate change and supply chain governance, into detailed subtopics, namely energy mix, greenhouse gases, supply chain human rights, and supply chain conflict minerals, respectively. The results continue to support our sustainability commitments and the initiatives highlighted in this report. This materiality matrix visually depicts the importance of each topic relative to two standards of valuation. The X-axis demonstrates the importance ascribed to each issue by the industry, and the Y-axis demonstrates each issue's importance to our stakeholders.
