These companies pollute to satisfy a demand. If people stopped driving cars, TotalEnergy and Shell would sell less oil.
Where these companies are evil is when they try to influence people and politicians. For example jay walking is a crime because of them.
That said taxing the hell out of these polluting industries is a solution, as it will raise the oil price and force people to consume less.
That's not exactly true. If you make parmigiano you have to follow pretty strict manufacturing procedures to ensure that the cheeses have the same taste.
It's pretty much the same thing as a brand except it's not produced by one structure but several independent structures. The main advantage is that you know what you are getting.
