Reporting guidelines and legal information

We developed this year’s Sustainability Report in accordance with the reporting guidelines and indicators of IPIECA, the global oil and gas industry association for environmental and social issues, the International Association of Oil and Gas Producers and the American Petroleum Institute.

Report Dec. 20, 2019

Reporting guidelines and legal information

Our report reflects the common reporting metrics of IPIECA, the International Oil and Gas Producers Association and the American Petroleum Institute Oil and Gas Industry Guidance on Voluntary Sustainability Reporting (2015). To help stakeholders easily access our key sustainability indicators, we have mapped relevant IPIECA and Global Reporting Initiative indicators and the U.N. Sustainable Development Goals in our content index.

This report focuses on ExxonMobil’s operations from January 1, 2018, through December 31, 2018, unless otherwise indicated. The report uses qualitative descriptions and quantitative metrics to describe our policies, programs, practices and performance. Note that 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. For environmental and climate change data, the report presents values in metric system units of measure. Financial information is reported in U.S. dollars. View previous reports or provide comments.

Cautionary note

Outlooks, projections, estimates, goals, descriptions of business and community plans, research efforts and other statements of future events or conditions in this report are forward-looking statements. Actual future results, including future earnings, returns to investors and other areas of financial and operating performance; future global energy supply, demand and mix; future distributions; proved and other reserves; reserve and resource additions and recoveries; the future effectiveness of safety, health, environmental and other sustainability risk and impact management processes; efficiency gains; and the timing and impact of future technologies could differ materially due to factors, including: 

  • Changes in demand, supply and pricing for oil and natural gas and other factors affecting the oil, gas, petroleum and petrochemical industries; 
  • Political and regulatory factors, including war, security disturbances, national tax policies, trade policies, environmental policies and the impact of international accords and treaties;
  • Changes in population size, purchasing power and consumer preferences; 
  • The timely completion of current exploration, development and construction projects;
  • Actions of competitors, including the development of competing technologies; 
  • The outcome of current and future research efforts and the ability to bring new technologies to scale on a cost-competitive basis; 
  • Technical and operating factors; and 
  • Other factors discussed in the document, Factors Affecting Future Results

Exxon Mobil Corporation has numerous affiliates, with many names including ExxonMobil, Exxon, Mobil, Esso and XTO Energy. For convenience and simplicity, those terms (and terms such as corporation, company, our, we and its) are sometimes used as abbreviated references to specific affiliates or affiliate groups. ExxonMobil is a publicly traded company. The New York Stock Exchange is the principal exchange on which Exxon Mobil Corporation common stock (symbol XOM) is traded. References to the resources, resource base, and recoverable resources, along with similar terms refer to the total remaining estimated quantities of oil and natural gas that are expected to be ultimately recoverable. ExxonMobil refers to new discoveries and acquisitions of discovered resources as resource additions. The resource base includes quantities of oil and natural gas classified as proved reserves, as well as quantities that are not yet classified as proved reserves, but that are expected to be ultimately recoverable. The term “resource base” is not intended to correspond to SEC definitions such as “probable” or “possible” reserves. The term “in-place” refers to those quantities of oil and natural gas estimated to be contained in known accumulations and includes recoverable and unrecoverable amounts. “Potential” resource amounts are not currently included in the resource base. The term “project” as used in this release can refer to a variety of different activities and does not necessarily have the same meaning as in any government payment transparency reports.
