Heard about a while back and super excited that it's implemented. One of the examples I remember is less polluting cement and steel. We know how to do it but it's marginally more expensive than "traditional" so companies producing it are on a small scale, mainly for "enthusiasts". Given this tax, the price for better steel/cement is going to be on par with the traditional and thus should incentives companies to buy it, thus reducing emissions in general. Reduction is the first and main part. So what if in 15 years we'll have tech to clean, if by then we make irreversible and expensive damage.
