This is an entire new element to the discussion ofc. In the current capatalistic world, I'd say: wait 10 years. Which pretty much sucks as an answer for you.

In Belgium, we have Wallonia. 4/5th of the country is a forest and Durbuy is getting an upgrade ( adventure, hotels,.. - lot of nature there). A lot of cities are banning the top polluting cars. I'm not sure if that information is helpful. Just a suggestion and some information to show progress. Ps. Removing sigarettes from a restaurant is feasible and already done (BE). It's not a possible economic disaster as removing traditional cars.
