Previously undisclosed documents released as part of a Massachusetts lawsuit against ExxonMobil reveal that the company's own scientists expressed doubts about the effectiveness of climate solutions the oil giant publicly promoted, including biofuels and carbon capture technology.

The documents, filed in the 2019 case and reported on by Inside Climate News via Ars Technica, include an internal memo from 1988 in which Frank Sprow of Exxon's corporate research department warned colleagues that if global action on greenhouse gases emerged, "substantial negative impacts on Exxon could occur." The memo was previously quoted by The Wall Street Journal in 2023 but has now been published in full.

The filings also contain more recent statements from Exxon scientists challenging the company's claims about its work on biofuels and carbon capture and storage. These documents are being reported on for the first time.

The disclosures come as part of an ongoing lawsuit brought by the state of Massachusetts against ExxonMobil, accusing the company of misleading investors and the public about climate risks and its own knowledge of climate science.

Analysis

Why This Matters

  • The documents suggest ExxonMobil may have internally recognized limitations in climate solutions it marketed as environmentally responsible.
  • The revelations could strengthen legal cases against the company and influence public perception of corporate climate pledges.
  • They add to a growing body of evidence regarding what oil companies knew about climate change and when.

Background

ExxonMobil has faced decades of scrutiny over its climate stance. In 1988, NASA climatologist James Hansen testified to Congress about global warming, and the UN established the IPCC. Internal company documents from that era have shown Exxon's research aligned with climate science, even as its public messaging sometimes differed. The Massachusetts lawsuit is one of several state-level cases seeking accountability for alleged deception.

Key Perspectives

ExxonMobil: The company has previously defended its climate research and investments in lower-emission technologies. It has argued that its public statements were consistent with evolving scientific understanding. Massachusetts Attorney General's office: The state maintains that Exxon misled investors and the public, and the newly disclosed documents support claims of internal doubt about the company's climate solutions. Critics: Environmental groups and climate accountability advocates say the documents show a pattern of corporate greenwashing, where companies promote solutions they know are insufficient.

What to Watch

  • Further document releases in the Massachusetts lawsuit and their impact on the case.
  • How other state and federal investigations into ExxonMobil's climate claims may be affected.
  • The company's public response and any changes to its climate messaging.
