How long do you think they'll continue to try to do something given the pressure this no doubt represents?
It's an interesting illustration of property rights. Air pollution is caused by private and public enterprise using the atmosphere as a dumping ground for waste products. For most of history, this has been seen as a fair trade-off. We like fire and we like the things fire makes possible. We'll put up with the smoke.
The problem with this public dumping ground model is at some point it impinges on private property and reduces it's value. A person's body is certainly private property and a person's health is the greatest factor in the value of a person's body. We don't buy and sell bodies, but we do spend a lot of money on maintenance. Air pollution increases maintenance costs and reduces overall value of the asset.
The $300 million dollars (the amount given in the article) has not actually been lost by the businesses of Mexico. It's a cost that has been transferred from the people who breathe the air, to the people who pollute the air. In reality, the polluters have been stealing from people for a very long time and now they can't do it anymore.
