New York State Is Finally Suing Exxon Mobil for Its Dishonest Actions on Climate Change

The misbehavior went as high up as former Secretary of State Rex Tillerson, previously the company’s chief executive.

New York state is suing the oil giant Exxon Mobil in a lawsuit that claims the company engaged in a “longstanding fraudulent scheme” to downplay the risks posed to its business by climate change regulations.

The legal action, launched by New York state Attorney General Barbara Underwood, alleges that Exxon Mobil deceived its investors by hiding the true extent of its financial exposure to laws aimed at curbing greenhouse gas emissions.


Exxon Mobil provided “false and misleading assurances” to shareholders that it had factored in climate regulations and that its vast reserves of oil and gas weren’t at major risk of being left as stranded assets, New York’s lawsuit claims.

Senior executives, including former Chief Executive Rex Tillerson, who was briefly secretary of state in the Trump administration before being abruptly fired earlier this year, took part in this facade, the lawsuit states.


The suit, lodged in the New York Supreme Court, comes after three years of investigation into Exxon Mobil by attorneys general in New York and Massachusetts. Exxon Mobil has previously attempted to block an investigation into its practices, claiming its First Amendment rights were being violated.

Underwood said, “Investors put their money and their trust in Exxon—which assured them of the long-term value of their shares, as the company claimed to be factoring the risk of increasing climate change regulation into its business decisions. Yet as our investigation found, Exxon often did no such thing.


“Instead, Exxon built a facade to deceive investors into believing that the company was managing the risks of climate change regulation to its business when, in fact, it was intentionally and systematically underestimating or ignoring them, contrary to its public representations.”

New York’s lawsuit paints a picture of corporate malfeasance whereby Exxon Mobil told investors it was applying a “proxy cost” to its extraction of fossil fuels to account for the risk of governmental action to address climate change. In practice, the lawsuit alleges, Exxon Mobil applied much lower proxy costs than it initially stated, essentially assuming that existing climate regulations would remain in place, unchanged.


This led to inaccurate information about investments in major projects, such as Exxon Mobil’s oil-sands operations in Alberta, Canada, the lawsuit states. Canada has recently outlined a national plan to put a price on carbon dioxide pollution in a bid to reduce emissions.


Exxon Mobil’s role in covering up the impact of climate change has come to light in recent years, with the company aware for decades about the consequences of burning fossil fuels only to downplay this in public.

The company now says it accepts that climate change is real and a threat, even pledging $1 million toward a campaign to put a price on carbon.

This support comes with the caveat that mounting lawsuits aimed at making Exxon Mobil pay for damage wrought by climate change are dismissed. In July, a federal judge kicked out a lawsuit lodged by New York City that took aim at the five major oil producers, including Exxon Mobil.

The New York state lawsuit does not concern the impact of climate change but rather Exxon Mobil’s role in communicating the risk of climate regulation to investors.


“Big oil may finally face some consequences for its role in wrecking the climate,” said Bill McKibben, co-founder of climate campaign group “The New York attorney general is standing up for investors who may have been swindled, and indirectly for the 7 billion of us who will suffer from Exxon’s lies.”


Exxon Mobil was contacted for comment.

Attorneys general in California and Illinois, asked if they would join the New York suit, said they planned to take a “close look” at the securities-fraud law the state is suing under.

The case “has been a topic of mutual conversation among various state AGs, and we are all going to take a close look at the filing,” California Attorney General Xavier Becerra said.

California would need to consider how its own laws apply, Becerra said. In Illinois, the power to join this type of case lies with the secretary of state, Attorney General Lisa Madigan explained.

She said, “The overall message here is that Exxon and others that were really at the forefront of causing climate change conditions in our country and around the world long knew that this was taking place and withheld that information to the detriment of not just their investors but ultimately all of us around the country.”
