Sempra Infrastructure and Mexico’s Federal Electricity Commission ended their agreement to develop the proposed Vista Pacífico LNG export terminal near Topolobampo, Sinaloa. The companies terminated the agreement in December 2025, and Sempra disclosed the decision on February 26, 2026.
Conservation groups welcomed the Vista Pacífico LNG cancellation because the terminal and its tanker traffic were planned for the Gulf of California, an exceptionally diverse marine region used by blue, fin, humpback, gray and sperm whales. But the cancellation does not remove every industrial threat facing the gulf, and Sempra’s filing attributed the decision to a change in corporate priorities—not solely to wildlife concerns.
Key takeaways
- Vista Pacífico was a proposed mid-scale LNG liquefaction and export terminal near Topolobampo, not an operating plant.
- Sempra and CFE agreed to end their development agreement in December 2025.
- Sempra publicly disclosed the termination in its 2025 financial reporting on February 26, 2026.
- Researchers and campaigners had warned that added tanker traffic could increase underwater noise, air pollution and collision risk for whales.
- The decision ends this specific proposal, but other shipping and energy projects still affect the Gulf of California.
What was the Vista Pacífico LNG project?
Vista Pacífico was designed as a medium-scale facility that would receive U.S.-sourced natural gas, cool it into liquefied natural gas and load it onto ships for export. A 2022 Sempra announcement described projected capacity of about 3.5 million metric tons per year.
The project was proposed near the port of Topolobampo on Mexico’s Pacific coast. From there, LNG carriers would have traveled through the Gulf of California toward markets across the Pacific.
Although some reports called Vista Pacífico a “megaproject,” it never became an operating terminal. That distinction is important: cancellation prevented a proposed new source of industrial activity rather than shutting down an existing plant.
Why was Vista Pacífico LNG canceled?
In its 2025 Form 10-K, Sempra said its infrastructure subsidiary and CFE agreed in December 2025 to terminate the development agreement “due to a change in their respective priorities.” Sempra’s current LNG portfolio page no longer lists Vista Pacífico among its active projects.
The proposal had also encountered regulatory difficulty. On February 11, 2026, a technical committee of Mexico’s National Energy Commission reportedly denied a natural-gas marketing permit associated with the project. Local reporting connected that setback with the project’s uncertain commercial future.
It would be too strong, however, to say that one permit denial or the environmental campaign alone definitively caused the cancellation. The company’s formal explanation was the change in priorities between the development partners.
Why whale advocates opposed the terminal
The Gulf of California supports one of the world’s richest assemblages of marine mammals. Its islands and protected areas were designated a UNESCO World Heritage Site in 2005, although the proposed terminal location itself should not be confused with the boundaries of every protected area in that designation.
The concern extended beyond construction at Topolobampo. LNG carriers would have had to move through whale habitat along a long shipping route. A 2025 technical report commissioned by environmental organizations modeled emissions and underwater noise from traffic associated with three proposed Gulf of California LNG projects.
The report projected that additional shipping could raise low-frequency underwater noise across habitat used by baleen whales. Large ships can mask communication, disrupt behavior and increase the risk of strikes. The analysis described potential impacts, not damage already caused by Vista Pacífico, because the terminal was never built.
Campaigners also raised concerns about dredging, local air quality, greenhouse-gas emissions and effects on fisheries and coastal communities. These issues helped build opposition under the “¿Ballenas o Gas?”—“Whales or Gas?”—campaign.
Which whales live in the Gulf of California?
The gulf is used seasonally or year-round by many cetaceans. Blue whales migrate into the region, where mothers with calves are regularly observed. Fin whales include a distinctive resident population, while humpback and gray whales use portions of the wider gulf during migration and breeding seasons. Sperm whales and numerous dolphin species also occur there.
Each species uses the seascape differently, so no single shipping-risk statement applies equally everywhere. Vessel speed, route, season, sound frequency and overlap with feeding or breeding areas all affect the level of risk.
Does the cancellation protect the whole Gulf of California?
No. Ending Vista Pacífico removes one proposed terminal and the tanker movements it could have generated. It does not create a new marine protected area, change all shipping routes or cancel unrelated port and energy projects.
Other sources of vessel noise, fishing pressure, coastal development, warming waters and pollution remain. Conservation groups therefore describe the decision as a meaningful gain, but not a complete solution for whales or coastal ecosystems.
What happens next?
The terminated Sempra–CFE agreement makes the original Vista Pacífico development plan inactive. Any future attempt to revive a similar project would require new commercial arrangements and applicable regulatory approvals.
For marine conservation, the case also highlights a growing planning question: environmental review of a coastal export terminal must consider the full shipping route, not only the land occupied by tanks and docks. For wide-ranging whales, the most important impacts may occur far from the facility itself.
Frequently asked questions
When was Vista Pacífico LNG canceled?
Sempra and CFE agreed to terminate their development agreement in December 2025. Sempra disclosed the decision publicly with its 2025 results on February 26, 2026.
Was Vista Pacífico LNG already operating?
No. It was a proposed liquefaction and export facility near Topolobampo. It had received some U.S. export authorizations, but construction and operation had not begun.
Did whale concerns alone stop the project?
That has not been established. Conservation opposition and regulatory setbacks formed part of the project’s context, while Sempra’s formal explanation cited changing priorities between the development partners.
Why can LNG shipping affect whales?
Large vessels generate underwater noise and carry collision risk. Effects vary by species and location, but noise can interfere with communication and behavior when shipping overlaps important habitat.
