Something that has been largely forgotten about is that it used to be routine to see pictures of smoggy Chinese and Asian cities, this was a problem for them that they solved. I can't help thinking we can't get this kind of preventative action on any large scale, we need to have severe issues first and that's not accounting for longer term/cumulative effects.
"Over the past years, the government has implemented various methods to improve the air quality in Northern China. Sandstorms, which were quite common 15 years ago, are now rarely seen in Beijing’s spring thanks to afforestation projects on China’s northern borders. The license-plate lottery system was introduced in Beijing to restrict the growth of private vehicles. Large trucks were not allowed to enter certain areas in Beijing. Above all, the coal consumption in Beijing has been restricted by shutting down industrial sites and improving heating systems. Beijing’s efforts to improve air quality has also been highly praised by the UN as a successful model for other cities. However, there is also criticism pointing out that the improvement of Beijing’s air quality is based on the sacrifice of surrounding provinces (including Hebei), as many factories were moved from Beijing to other regions."

CO2 emissions are a different kind of "pollution". They are not visible and diffuse quickly over the whole Earth.
