The Sustainability Report Highlights summarizes ExxonMobil’s approach to managing our operations and describes our environmental, social and governance performance. This report focuses on 10 key topics for our business. For further information on all topics that are important to ExxonMobil, please visit our website . We developed this year’s report in accordance with the reporting guidelines and indicators of IPIECA, the global oil and gas industry association for advancing environmental and social issues, the International Association of Oil and Gas Producers (IOGP) and the American Petroleum Institute (API). This report focuses primarily on ExxonMobil’s operations from January 1, 2019, through December 31, 2019, unless otherwise indicated, since full-year 2020 data were not available at the time of publication. This report uses qualitative descriptions and quantitative metrics to describe our policies, programs, practices and performance. Many of the standards and metrics used in preparing this report continue to evolve and are based on management assumptions believed to be reasonable at the time of preparation, but should not be considered guarantees. Materiality assessment Consistent with IPIECA’s Oil and Gas Industry Guidance on Voluntary Sustainability Reporting, ExxonMobil began conducting annual “materiality assessments” in 2006 to identify environmental, social and governance issues of particular interest to our stakeholders and to ensure our analysis reflects events and changing business priorities. The results of our assessment help inform the development of this report. Read more about our materiality assessment . We list the material issues for the full Sustainability Report below. For the purposes of this report, the concept of “material issues” refers to IPIECA reporting guidance on potential disclosures and does not correspond to the concept of materiality used in the securities laws and disclosures required by U.S. Securities and Exchange Commission rules.
