Why would anyone go to jail? I know eating beef is bad for the environment and I eat beef. I wouldn't even mind if there was an externality tax I had to pay, but I don't see why anyone should be obligated to take into account every possible indirect harm their action might cause that is not regulated. Did Chevron break any specific existing rules?

Somebody could decide retroactively that you circling a parking lot to find a better spot knowing you release CO2 was unjustified and you need to be punished. These lawsuits are exactly that - arbitrary petsonalistic extortion.
