'There is No Doubt': Exxon Knew CO2 Pollution Was A Global Threat By Late 1970s

Throughout Exxon’s global operations, the company knew that CO2 was a harmful pollutant in the atmosphere years earlier than previously reported. DeSmog has uncovered Exxon corporate documents from the late 1970s stating unequivocally “there is no doubt” that CO2 from the burning of fossil fuels was a growing “problem” well understood within the company.

Those lines appeared in a 1980 report, “Review of Environmental Protection Activities for 1978-1979,” produced by Imperial Oil, Exxon’s Canadian subsidiary.

A distribution list included with the report indicates that it was disseminated to managers across Exxon’s international corporate offices, including in Europe.[click here to download the full PDF version of “Review of Environmental Protection Activities for 1978-1979”] The next report in the series, “Review of Environmental Protection Activities for 1980-81,” noted in an appendix covering “Key Environmental Affairs Issues and Concerns” that: CO2 / GREENHOUSE EFFECT RECEIVING INCREASED MEDIA ATTENTION.[click here to download the full PDF version of “Review of Environmental Protection Activities for 1980-1981”]InsideClimate News unveiled much new information in its Exxon: The Road Not Taken series clearly demonstrating the depth of climate science knowledge among Exxon’s U.S. operations. Additional revelations about the company’s early climate research were published by the Los Angeles Times in collaboration with the Columbia School of Journalism.  A 1980 Exxon report explained the company’s plans:

Now DeSmog’s research confirms that the knowledge of the carbon dioxide pollution threat was indeed global across Exxon’s worldwide operations, earlier than previously known, and considered a major challenge for the company’s future operations. The new documents revealed today were found by DeSmog researchers in an Imperial Oil (TSE:IMO) archival collection housed at the Glenbow Museum in Calgary, Alberta. We first learned of the existence of the collection in one of the articles published in the Los Angeles Times in collaboration with the Columbia School of Journalism.

A document discovered by DeSmog reveals that Exxon was aware as early as the late 1960s that global emissions of CO2 from combustion was a chief pollution concern affecting global ecology. Those details were found in a 1970 report, “Pollution Is Everybody’s Business,” authored by H.R. Holland, a Chemical Engineer responsible for environmental protection in Imperial Oil’s engineering division. [click to download PDF of “Pollution is Everybody’s Business] Holland wrote:

Included in Holland’s report is a table of the “Estimated Global Emissions of Some Air Pollutants.” One of those “air pollutants” on the table is carbon dioxide with the listed sources as “oxidation of plant and animal matter” and “combustion.”

The double asterisks beside CO2 in Holland’s list of pollutants refer to a citation for a 1969 scientific study, “Carbon Dioxide Affects Global Ecology,” in which the author explains the connections between the burning of fossil fuels, the rise in CO2 in the atmosphere and the potential effects this will have on future weather patterns and global temperatures.  

Holland emphasized the need to control all forms of pollution through regulatory action, noting that “a problem of such size, complexity and importance cannot be dealt with on a voluntary basis.” Yet the fossil fuel industry has long argued that its voluntary programs are sufficient, and that regulations are unneeded.

Despite Exxon’s advanced scientific understanding of the role of CO2 pollution from fossil fuel burning causing atmospheric disruption, the company shelved its internal concerns and launched a sophisticated, global campaign to sow doubt and create public distrust of climate science. This included extensive lobbying and advertising activities, publishing weekly op-eds in The New York Times for years, and other tactics.
