I imagine there is an upper limit to how many people they can convince to care about this stuff, and that limit is probably lower than the level needed to achieve their goals, so i don't see this progressing beyond temporary excursions into virtue signal naivete that will get rolled back in time.
To me the only real way to get their agenda implemented is through innovation and the free market. They need to invent better and cheaper products to solve for every evil they list as destroying the environment and consumers will embrace them as superior and will move over en masse. If you don't like cow farts, as hard as it is, invent fake meat that's better tasting and cheaper than real meat. Anything short of that will not breach a fairly low limit of interest by a select few who care about this stuff. Artificially inflating the price of meat through taxes isn't going to create meaningful lasting change if that's their goal. Soon the loss of competitiveness of their cash cow will render the idea as kind of foolish to begin with once the economic impact becomes clear or a rogue competitor choosing not the comply with the agenda wins the battle.
Don't like plastics? Then invent something that's cheaper and better that degrades quickly as it finds it's way into the ocean or landfills. Don't like Ice vehicles? Invent superior electric ones, and then invent a cheaper energy generation alternative and batteries that last 50 years so the manufacturing damage to the environment is limited. Don't like coal and it's effects? Well who cares because once fusion or something similar is figured out in a couple decades they can deploy carbon scrubbers the world over and suck carbon out of the atmosphere with that cheap power.
The point of that last paragraph is just to say that i imagine innovators will solve the problem long before virtue signalers busying themselves with a vigorous shuffling of deck chairs on the Titanic will. Innovators will do their thing and the iceberg will lose and the ship will continue on it's journey.
Follow the money may be a cynical and lazy idea some of the time and yet most of the time it explains so much when it comes to the next greeny policy idea.
Stop worrying and enjoy the ride.
