They say there is a solution to the problem so regulators let them pollute more and make more money. Eventually we all figure out they lied and it doesn't work or they don't use it and then they get a tiny fine. Business as usual.
Huh? You could say that about any cost at all. Yet, companies are constantly on the look out for ways of cutting costs. Use less material, use less labour, pay lower fines, find a way to optimize taxes, etc.
