Greenhouse gas emissions performance data1

We assess our performance to support continuous improvement throughout the organization using our Environmental Performance Indicator (EPI) process. The reporting guidelines and indicators in the Ipieca, the American Petroleum Institute (API), the International Association of Oil and Gas Producers Sustainability Reporting Guidance for the Oil and Gas Industry (4th edition, 2020, revised February 2023), and key chapters of the GHG Protocol inform the EPI and the selection of the data included in this performance table. The following data table is based upon IPCC AR6.2,3

Environmental Resources Management CVS has provided their independent limited level of assurance that the 2023 ExxonMobil greenhouse gas emissions inventory meets ISO 14064-3 expectations. ERM CVS Assurance Statement. 2024 third-party assurance underway.

FOOTNOTES FOR GREENHOUSE GAS EMISSIONS PERFORMANCE DATA:

  1. Greenhouse gas emissions (GHG) performance data reflects a change in methodology for asset specific density when estimating GHG emissions intensity.
  2. Based on Scope 1 and 2 emissions of ExxonMobil operated assets through 2024 (versus 2016). ExxonMobil’s reported emissions, reductions, and avoidance performance data are based on a combination of measured and estimated emissions data using reasonable efforts and collection methods. Calculations are based on industry standards and best practices. There is uncertainty associated with the emissions, reductions, and avoidance performance data due to variation in the processes and operations, the availability of sufficient data, quality of those data, and methodology used for measurement and estimation. Performance data may include rounding. Changes to the performance data may be reported as part of the company’s annual publications as new or updated data and/or emission methodologies become available. We are working to continuously improve our performance and methods to detect, measure and address greenhouse gas emissions. ExxonMobil works with industry to improve emission factors and methodologies, including measurements, and estimates. Scope 1 and 2 emissions and intensity totals are calculated using market based method for Scope 2.

  5. Includes indirect emissions from imported electricity, heat, steam, and cooling.
  6. Includes indirect emissions from imported electricity, heat, steam, and cooling; incorporates the purchase of energy attribute certificates (renewable energy certificates, guarantees of origin).
  7. The net GHG metric includes Scope 1 GHG emissions and Scope 2 GHG emissions (market-based), excluding emissions from exported power and heat.
  8. Mass of CO2 that was captured for applications such as geologic sequestration, acid gas injection, enhanced oil and gas recovery, including capturing CO2 for third parties or customers.
  9. ExxonMobil 2030 GHG emission-reduction plans are intensity-based and for Scope 1 and 2 greenhouse gas emissions from operated assets compared to 2016 levels.

Portfolio life-cycle emissions intensity

Individual projects or opportunities may advance to a final investment decision by the company based on a number of factors, including availability of supportive policy and permitting, technology and infrastructure for cost-effective abatement, and alignment with our business partners and other stakeholders. Actual avoided and abated emissions may differ.

For more information on the potential impact of our investments see our Corporate Plan Update.

Using a life-cycle approach and applying it to ExxonMobil’s business plans through 2030, we expect an 8% reduction in full life-cycle emissions intensity and an estimated 6% increase in full life-cycle absolute emissions, inclusive of growth in our natural gas business and the acquisition of Pioneer. These are in comparison to 2016 levels.

A life-cycle approach was used to develop our proprietary portfolio life-cycle intensity model, which estimates direct and indirect emissions for our Upstream, Product Solutions, and Low Carbon Solutions businesses. The estimated figures are based on our projected 2024 Corporate Plan volumes for 2030. The portfolio life-cycle emissions intensity calculation is based upon the emissions associated with the mass of products delivered to the market.

Scope 3 emissions

The table below provides Scope 3 estimates associated with the use of our natural gas and crude production in alignment with Category 11 of Ipieca’s methodology, which contemplates accounting for products at the point of extraction, processing, or sales. Scope 3 estimates represent three approaches for accounting and are not meant to be aggregated, as this would lead to duplicative accounting.

Estimated total Scope 3 emissions from the use of ExxonMobil’s crude and natural gas production for the year ending Dec. 31, 2024, as provided under Ipieca’s Category 11 were 630 million metric tons.

For example, for completeness, the Scope 3 estimates associated with the combustion of the crude produced, processed from our refineries, or sold are provided; however, to avoid duplicative accounting, these Scope 3 estimates are not included in our Scope 3 Category 11 total, since the associated Scope 3 emissions would have been reported by the producer of those crudes.

Applied CO2 emission factors were obtained from EPA or derived from API calculations; where applicable, emission factors for specific fuel products were applied. Non-fuels products are not combusted by the end user and therefore are not included in these Scope 3 estimates. Ipieca’s Scope 3 methodology includes 15 categories of activities along each product’s value chain. Due to limited third-party data, Scope 3 emissions for categories other than Category 11 are not provided. Scope 3 guidelines are based on the GHG Protocol.

We do not set Scope 3 targets. Using the GHG Protocol to measure and manage company or sector-wide emissions is flawed and counterproductive. It also ignores growing energy demand, enabling no comparison of alternative ways to meet that demand.

To meet a net-zero goal, it is essential that companies fully understand their net emissions and have a means of comparing themselves against others in their industry. Most importantly, the approach needs to equip and incentivize companies to make investments that will reduce their emissions or the emissions of their customers when providing low carbon solutions – not simply encourage companies to back away from meeting society’s needs and pass portions of their carbon footprint to someone else.
