Exxon Mobil issued its first public statement that burning fossil fuels contributes to climate change in 2006, following years of denial. In public forums, the company argued that the risk of serious impact on the environment justified global action. Yet behind closed doors, Exxon took a very different tack: Its executives strategized over how to diminish concerns about warming temperatures, and they sought to muddle scientific findings that might hurt its oil-and-gas business, according to internal Exxon documents reviewed by The Wall Street Journal and interviews with former executives.
Exxon’s public acceptance in 2006 of the risks posed by climate change was an early act of Rex Tillerson, an Exxon lifer who became CEO that year. Some viewed him as a moderating force who brought Exxon in line with the scientific consensus.
The documents reviewed by the Journal, which haven’t been previously reported, cast Tillerson’s decadelong tenure in a different light. They show that Tillerson, as well as some of Exxon’s board directors and other top executives, sought to cast doubt on the severity of climate change’s impacts. Exxon scientists supported research that questioned the findings of mainstream climate science, even after the company said it would stop funding think tanks and others that promoted climate-change denial.
Exxon is now a defendant in dozens of lawsuits around the U.S. that accuse it and other oil companies of deception over climate change and that aim to collect billions of dollars in damages. Prosecutors and attorneys involved in some of the cases are seeking some of the documents reviewed by the Journal, which were part of a previous investigation by New York’s attorney general but never made public.
One of the lawsuits is from Hawaii’s Maui County, where wildfires killed more than 100 people in August. The lawsuit, filed in 2020, alleged the island faced increased climate-related risks, including more dangerous wildfires, caused by fossil-fuel companies. Some of the lawsuits may go to trial as soon as next year.
“I know how this information looks—when taken out of context, it seems bad,” Exxon CEO Darren Woods said in response to the Journal’s inquiry about the documents. “But having worked with some of these colleagues earlier in my career, I have the benefit of knowing they are people of good intent. None of these old emails and notes matter though. All that does is that we’re building an entire business dedicated to reducing emissions—both our own and others—and spending billions of dollars on solutions that have a real, sustainable impact.”
