Some industries, like the pharmaceuticals, may not be able to switch away from mineral oils so easily. That's why I prefer a balanced approach that makes unnecessary or even luxurious things way more expensive. The carbon tax approach would work in terms of "reducing carbon" but the people who are already struggling in day to day life would be hit the hardest. Those are the poor folks that have to commute to work with older cars because their bosses decided that there is no more home office.

The government making a list of what is wasteful and what not would probably fail, you're right about that. In the long term the carbon tax is a good solution. It's easy to implement but that doesn't mean that it's easy to make the transition for many people. And by "not easy" I don't mean "stop eating meat because of the carbon", which would be very easy compared to "buy 3 times more expensive gas to go to work or buy food for the week and loose your job".
