Exxon Advertised Against Climate Change for Decades After Top Executives Knew Burning Fossil Fuels Would Warm the Planet

ExxonMobil went on to advocate a “strong focus on scientific understanding” around climate change and proposed policies “that have the potential to make significant longer-term reductions in emissions, if they are needed.” 

The ad finished with this: “Although it is hard to predict what the weather is going to be this weekend, we know with certainty that climate change policies, unless properly formulated, will restrict life itself.”

A week later, on March 23, 2000, ExxonMobil’s ad, “Unsettled science” focused on a 1996 study on temperature and climate in the Sargasso sea. At the company AGM in May that year Lee Raymond gave a presentation arguing the study showed how past temperatures appeared warmer than today, long before people began burning fossil fuels.

“So the issue isn’t only: is the earth warming, but why is it warming,” Raymond told the meeting.

In a letter in response to ExxonMobil’s use of his work, the author of the study, Dr Lloyd Keigwin, wrote:

“I believe ExxonMobil has been misleading in its use of the Sargasso Sea data. There’s really no way these results bear on the question of human induced climate warming…I think the sad thing is the a company with the resources of ExxonMobil is exploiting the data for political purposes.”

ExxonMobil then moved to a touch of greenwashing, a prominent feature of many of its Op Ads. In “The Promise of Technology”the company emphasized its push to explore new technology, especially it project on hydrogen/petroleum cars, research that kept a focus on cars at least in part powered by Exxon’s climate-changing product, which hasn’t produced any results, and which has since been surpassed by the development of electric cars. Yet it still managed to keep a question mark over the science of climate change with this line: “Climate change may pose legitimate long term risks.”
