Exxon Mobil Investigated in New York Over Possible Lies on Climate

The New York attorney general has begun a sweeping investigation of Exxon Mobil to determine whether the company lied to the public about the risks of climate change or to investors about how those risks might hurt the oil business.

According to people with knowledge of the investigation, Attorney General Eric T. Schneiderman issued a subpoena Wednesday evening to Exxon Mobil, demanding extensive financial records, emails and other documents.

The focus includes the company’s activities dating to the late 1970s, including a period of at least a decade when Exxon Mobil funded groups that sought to undermine climate science.

Mr. Schneiderman’s decision to scrutinize the fossil-fuel companies may well open a sweeping new legal front in the battle over climate change. To date, lawsuits trying to hold fossil-fuel companies accountable for the damage they are causing to the climate have been failing in the courts, but most of those have been pursued by private plaintiffs.
