At this point, the idea that fossil fuel companies are actually interested in trying to help save the planet in any way more than is mandated by law and public opinion is not supported by evidence. They have shown, time and again, that they will lie about science, falsify documents, and try to get laws changed to allow them to pollute without limits. They have lost all benefit of the doubt. Anyone trying to argue that they have any genuine interest in helping to save the planet is making an extraordinary claim, and needs to back it up with extraordinary evidence.
