The Mexican government is considering promoting a regional initiative to transform the sargassum into aviation biofuel. The proposal involves the creation of a multinational company with countries from Central America and the Caribbean, a measure that would not only address a shared environmental issue but also provide an alternative to the international obligation to reduce emissions from commercial flights.
The International Civil Aviation Organization established that airlines must progressively decarbonize their operations starting in 2027. In this context, the utilization of sargassum as a raw material emerges as a strategic opportunity. The Ministry of Environment and Natural Resources (Semarnat) is driving the plan as part of the transition to a circular and low-carbon economy.
Currently, sustainable aviation fuel costs more than three times the price of conventional jet fuel. To narrow this gap, the state-owned company Airports and Auxiliary Services (ASA) has announced a multimillion-dollar investment to expand its plant in Cancun, where biofuel will be produced from waste oil and, in the future, from sargassum.
The project would allow for an energy use of one of the most problematic macroalgae in the Caribbean, which covers thousands of kilometers of beaches each year, generating significant environmental, economic, and social impacts. However, experts warn that fuel production alone does not solve the risks associated with its massive accumulation on the coasts.

## An ecological alternative to harness this macroalgae
The utilization of sargassum as sustainable fuel is proposed as a promising alternative to convert an environmental liability into an energy opportunity. However, experts insist that the key lies in designing comprehensive policies: from safer collection systems to investments in research to better understand the cycle of this macroalgae.
In a scenario of global climate crisis, the challenge is not only to transform waste into energy but also to ensure that the solutions consider both environmental protection and the well-being of the communities that depend on the sea.

The uncontrolled arrival of sargassum in Mexico and other Caribbean countries has altered the dynamics of coastal ecosystems. The accumulation of tons of algae on beaches causes the death of fish, turtles, and corals by hindering water oxygenation and releasing toxic substances during decomposition. These processes deteriorate essential habitats for marine biodiversity.
The impact also affects human communities. In Quintana Roo, beach cleaning is largely done manually and under unsafe conditions for workers. The decomposition of sargassum produces gases that can cause respiratory and skin problems, turning collection into a health risk.
Furthermore, the presence of large volumes of algae directly affects tourism, the region’s main economic driver. Hotels and municipalities invest millions of pesos each season in removing sargassum, but the phenomenon continues to intensify due to climate change and pollution that fuels its proliferation in open sea.
The declaration of a national emergency, repeatedly requested, aims to ensure resources and federal-level coordination to tackle the problem. Without structural measures, the pressure on ecosystems and coastal communities will continue to increase.
