Overview
- The federal government reports the ammonia plant at Bahía de Ohuira is about 95 percent finished and in the final phase of construction.
- President Claudia Sheinbaum and Semarnat cite an approved environmental impact study and a prior public consultation that they say backed the project.
- Local mayo‑yoreme communities and environmental activists maintain ongoing blockades and occupations of plant access to oppose operation over health, ecological and cultural concerns.
- The plant developer is Proman GPO, a German‑linked firm, and a UNAM researcher has publicly defended the project's environmental viability, saying it will not discharge ammonia to the sea and that cooling effects will be limited.
- The Economy Ministry says the facility would produce 800,000 tonnes of ammonia a year, cut more than 70 percent of fertilizer imports and save about $500 million annually, a change that could affect local fishing, employment and regional supply chains.
