Additionally if no one is buying products from heavy polluters then it doesn’t make sense to burn the fuels. It either requires people to take action and change their buying habits or for governments to tax carbon to both make the environmentally friendly options economically viable to most people and to get companies to reduce emissions so they can stay competitive.
Air travel is more difficult to get environmentally friendly at this time due to the limited options as electric consumer planes are still in the testing and development stage and would struggle with international flights however train travel in Europe can be a solid option over plane travel but from a US perspective air travel is still generally the best way to go as trains are just not the best in the US and a car trip will take longer then both planes and trains and emit more fossil fuels per trip per person.
there is a few exceptions for this rule like self employed and individual contractors and sometimes if you work for a very small business however they are exceptions, for almost everyone else it should just be a bill that can be contested if there is issues.
