I am not really sure of what it means for a company "to lie". And I'm not sure it's illegal even for a person to lie, except under oath or in official investigations. A company can falsify official documents, but that would be fraud, and I think it's limited to financial matters, where there are precise algorithms to follow. Then there is false advertisement, but this as well, needs to say something definitely wrong about intrinsic characteristics of the product. As far as I know (not much, in truth) allegations are that some Exxon scientist informed the management board of the concerns in the scientific community about climate change; the board simply decided that the risks were too far away in time and too uncertain, while the alternatives simply weren't there, for the company to take action upon this information. Which sounds like a perfectly reasonable conclusion in 1982. Also, throughout the years, Exxon seems to have financed and published sound climate science, while at the same time emphasizing the uncertainty of the conclusions in the communication for the general public. And again, this seems to be legitimate, as it is in everybody's right to state the facts as they are, while trying to spin them in the least damaging way for themselves. Again, if the peer reviewed science was so sound, and publicly available, it was the duty of the government and politics to act upon it, not of the very companies that sold the product.
