Environmental Groups Warn Japan's Largest Bank of Legal, Financial Risks in Fossil Gas Export Project

Strategic Insights -

As UNESCO assesses the Gulf of California World Heritage Site, environmental legal groups ClientEarth USA and the NRDC have warned Japan's largest bank, MUFG, that its support for a massive fossil gas export project could expose the bank to serious legal, financial, and reputational risks. The proposed Saguaro Energia liquified natural gas (LNG) terminal would export U.S. fracked gas to Asian markets, threatening the region's extraordinary marine biodiversity.

Key Takeaways:

  • The Saguaro Energia project is a liquified natural gas (LNG) terminal that would export U.S. fracked gas to Asian markets, cutting through the ecologically sensitive Gulf of California, an area known as the "aquarium of the world".
  • The project would emit 5.7 million metric tons of CO2 and lifecycle emissions equivalent to 17.4 million cars each year, making Mexico the fourth largest LNG exporter in the world.
  • UNESCO and marine scientists have raised alarms over the Gulf's health, warning that increased industrial shipping could harm endangered species, blue and fin whales, sea lions, and other vulnerable marine life.
  • The bank, MUFG, is acting as a financial advisor on the project, which is being developed by U.S.-based firm Mexico Pacific and is currently blocked by a court injunction.
  • The project has been characterized by experts as financially unviable and in danger of becoming a stranded asset long before it generates returns, with cost overruns, executive instability, permitting failures, and shifting LNG market conditions.
  • The principal investor, Quantum Capital, exited its stake in early 2025, leaving the project without a clear financial backing.
  • The project would make the Gulf of California a major industrial shipping route, posing a threat to the area's already vulnerable ecosystem.
  • The World Heritage Committee has listed the Gulf of California as "in danger" since 2019 due to biodiversity loss, illegal fishing, and the rapid decline of the vaquita porpoise, the world's most endangered marine mammal.

Statistics:

  • The Saguaro Energia project would emit 5.7 million metric tons of CO2 and lifecycle emissions equivalent to 17.4 million cars each year.
  • The project would make Mexico the fourth largest LNG exporter in the world.
  • The Gulf of California is home to 11 species of whales and almost 40% of all marine mammal species.
  • The vaquita porpoise, the world's most endangered marine mammal, has only six to eight individuals remaining due to illegal fishing and inadequate enforcement of protections.
