Proman’s global footprint
Proman is a global leader in methanol, fertilizer and other natural gas derived products. Headquartered in Switzerland, with assets in the United States, Trinidad and Oman, and ongoing expansion into Mexico and the United Arab Emirates (UAE), Proman is the largest aggregated methanol and ammonia producer in the world and has extensive experience in petrochemical plant operations, petrochemical and power plant construction, product marketing and logistics, and project management. Proman is committed to developing low-carbon and green methanol and ammonia as cleaner alternatives to fossil fuels, offering a pathway to drastically cutting emissions in a range of sectors including transport, power and industry.
Across its operations, Proman applies the same commitment to safety, reliability, and sustainability that underpins Proman GPO. With over 40 years of global experience, Proman provides GPO with proven engineering, construction, and operational expertise, ensuring that the Topolobampo plant meets world-class standards in efficiency and environmental care. The facility is being built with automated safety controls, energy-efficient processes, and low-emission technology to ensure minimal environmental impact.
At our facilities in Trinidad, carbon dioxide that is generated during ammonia production is captured and reused in the manufacture of methanol and urea, helping reduce emissions and improve resource efficiency. This approach informs how Proman GPO is planning and developing its environmental management approach in Mexico, including future opportunities for efficiency and circular practices once the plant is operational.
Proman GPO is backed by Proman, a top ten global nitrogen fertilizer producer with three ammonia plants and 1.9 million tonnes of annual capacity. This experience strengthens our work to support Mexico’s farmers and fertilizer supply.
Strong partnerships in Mexico
Proman GPO collaborates with CFE, CFEenergía and PEMEX to ensure reliable access to natural gas and essential industrial infrastructure. These partnerships strengthen Mexico’s petrochemical value chain and demonstrate how public and private collaboration can deliver sustainable, long-term benefits for the country. We also work with local suppliers and contractors, building capacity, transferring knowledge, and generating opportunities that support regional development.
Frequently asked questions
Proman GPO maintains open and transparent communication with the community. Below are answers to the questions we are most often asked. If you would like to learn more, please contact us at info.gpo@proman.org.
Why a petrochemical project in Sinaloa?
Access to natural gas in Sinaloa paves the way for the development of the petrochemical industry. Mexico currently imports around 80% of the ammonia it consumes, and in 2024, it imported 3.7 million tonnes of nitrogen-based fertilizers*. Once operational, Proman GPO will help reduce import dependency by over 70%, making high-quality ammonia available locally and contributing to Mexico’s agricultural and food self-sufficiency.
With an initial investment exceeding USD 1.6 billion, Proman GPO is building the most modern and safest fertilizer plant in the world, strengthening national supply, the agricultural chain, and regional development. The facility will be the largest merchant ammonia plant in Latin America with a production capacity of 2,220 MT/day when completed.

Why is the project located within a wetland conservation area designated as being of international importance under the Ramsar Convention?
The future plant is situated in an area that was already developed, with no vegetation or fauna, as verified by the Secretariat of Environment and Natural Resources (SEMARNAT) during the environmental assessment.
The project does not affect the ecosystem services of the Ramsar site nor interfere with migratory bird habitats. Proman GPO is implementing conservation programmes for species such as mangroves, dolphins, turtles, birds, and aquatic flora.
Globally and nationally, several industrial projects have been approved within Ramsar sites (for example, in Argentina, the Netherlands, Germany, and Mexico), provided they comply with regulations and environmental impact studies, as is the case with this project, which is supported by legal instruments and the Regional Environmental Impact Assessment (MIA).
What impact will the plant have on shrimp fishing and other species?
In an area previously affected by industrial activity, where conditions for shrimp habitat had declined, Proman GPO is supporting the recovery of the bay through water quality improvements, habitat rehabilitation and the restocking of blue shrimp. We also promote responsible practices during the closed season, the legally required period when fishing is paused to protect breeding and allow shrimp populations to regenerate.
What benefits will the project bring to the community?
The project will contribute to the local economy in several ways. It will create direct and indirect employment opportunities during construction and future operations, with a focus on hiring local talent and providing training so that people can develop long-term skills and careers.
It will also strengthen local supply chains by working with businesses in the region, encouraging the growth of small and medium-sized enterprises.
In addition, the project includes investment in public infrastructure and community programmes that support education, sports, fishing, health, cultural preservation and support for women. These initiatives aim to improve living conditions, reduce marginalisation and create opportunities for families in the region to thrive over time.
Our goal is to ensure that the benefits of the project are shared locally and contribute to sustainable development in Sinaloa.
What environmental programmes is Proman GPO implementing?
Actions have been launched to restore the Santa María–Topolobampo–Ohuira lagoon system, with the involvement of conservation experts.
Programmes include flora and fauna monitoring, mangrove protection, conservation of migratory birds and marine species, and sustainable environmental management.
