About This Report General Motors is committed to publicly reporting on sustainability-related topics on an annual basis, discussing the opportunities and challenges that we encounter as we work to enhance performance and conduct business in the most responsible manner possible. This report has been prepared according to Global Reporting Initiative (GRI) Standards: Comprehensive Option and includes responses to the Sustainability Accounting Standards Board (SASB) framework—Transportation Standards and the Financial Stability Board Task Force on Climate-related Financial Disclosures (TCFD). Responses to sustainability-related frameworks and standards as well as assurance statements can be found in the 2021 Sustainability Supplement, which is available for download on gmsustainability.com. This report covers certain sustainability metrics and data for GM as of and during the year ended December 31, 2021, as applicable, unless otherwise stated. In instances where select information is provided from an earlier period or early 2022, that is noted in the report. The report is limited to automotive operations wholly owned and/or operated by GM. Unless otherwise stated, GM Financial, our financing services provider, and Cruise, our autonomous vehicle subsidiary, are not included in the report. In some instances, data has been included for operations in which GM’s interest is through joint ventures, including our automotive China joint ventures. In these instances, the inclusion of that data is noted. Dollar amounts presented within this report are stated in U.S. dollars. This report was published on April 28, 2022. We annually contract an independent third-party verification of a selection of greenhouse gas (GHG) and certain sustainability data assertions for our global operations. The verification statements and applicable data assertions can be found in the 2021 Sustainability Supplement. This report provides an overview of some of GM’s long-term goals and aspirations, and efforts in support of those goals and aspirations. Some material is derived from other company documents, and links are provided to those documents where appropriate. With respect to goals, commitments and aspirational or otherwise forward-looking statements in this report, actual results may differ, possibly materially. The report also includes certain numbers that are estimates or approximations and that may be based on assumptions. We believe that the estimates employed are appropriate and reasonable; however, due to inherent uncertainties in making estimates and assumptions, actual results could differ from the original estimates. Additional information with respect to forward-looking statements can be found on page 120 .
