co2 and air pollution are not the same thing (if global warming weren't real). While it is fairly viable economically to scrub mercury emissions out of a coal plant, or carbon monoxide out of a car,it is effectively impossible to scrub co2. So people in the industry that depends on fossil fuels know this, they know the only answer to getting co2 out of the atmosphere is to not use fossil fuels at all, which is an extremely hard/expensive thing to do. Moonshot level project, globally. Some just worry about their own riches, others rightly worry it would cause global disaster (it could if we did it wrong!)
