Louisiana bets big on 'blue ammonia.' Communities along Cancer Alley brace for the cost.

An extensive review by Floodlight found no evidence that existing carbon capture projects anywhere in the world have achieved anything close to the emissions cuts companies like CF Industries are promising. Permit documents, meanwhile, show that the proposed plants combined could be allowed to discharge more than 2,800 tons each year of air pollutants (not greenhouse gases), including more than 400 tons of ammonia.
