In its 2024 fourth quarter update, NextDecade, a Houston-based liquefied natural gas company, announced its intention to more than double its export capacity at the Rio Grande LNG facility near Brownsville, Texas. Despite NextDecade’s sunny projections, community members and investors in the project’s owner, Global Infrastructure Partners, and its parent company, BlackRock, should be wary of risks associated with the LNG facility. The proposed expansion could further harm local communities, the region, and pose significant risks to investors.
LNG is primarily composed of methane, a potent greenhouse gas with 80 times the atmospheric warming potential of carbon dioxide over a 20-year period. As originally proposed, this project was estimated to emit the equivalent emissions of 44 coal power plants every year, about 163 million tons of carbon dioxide annually. The newly announced expansion would be projected to emit over 300 million tons of carbon dioxide equivalent every year, or the equivalent of the emissions from 83 coal plants annually.
Perhaps in an effort to address criticism about emissions, NextDecade’s original proposal included carbon capture and storage (CCS), though some opponents described this as greenwashing from the beginning. The company withdrew its CCS application with the Federal Energy Regulatory Commission (FERC) in August 2024, yet continues to tout sustainability on its website.
The path forward demands a just transition to clean energy that respects both people and the planet.
The Rio Grande LNG facility sits in a region already burdened by economic hardship and environmental injustice. Its expansion will amplify air pollution, exposing local residents—many of whom are Latino and low-income—to increased risks of respiratory illnesses, cancer, and other serious health conditions.
Several nearby towns and entities formally oppose the project, including Laguna Vista, South Padre Island, Port Isabel, and the Laguna Madre Water District. The Rio Grande LNG terminal is being built on the sacred land of the Carrizo/Comecrudo Tribe of Texas, yet Rio Grande LNG, regulatory agencies, and banks have failed to consult with that Tribe on its impacts.
Additionally, according to an environmental report,, the facilities will likely significantly degrade local fishing, shrimping, and natural tourism industries, putting communities’ livelihoods at risk. The project also threatens critical wetlands adjacent to the Laguna Atascosa National Wildlife Refuge, which protects endangered species such as the ocelot and Kemp’s Ridley sea turtle. The noise, light, and industrial activity will disrupt fragile ecosystems and threaten biodiversity. The opposition shines a light on the environmental risks inherent in this project.
Rio Grande LNG has faced significant challenges, including pending approval and permitting of the project from the Federal Energy Regulatory Commission. Some banks and insurance companies have wavered in their support. Long before the expansion announcement, insurance company CHUBB backed out of the project. Societe Generale, BNP Paribas, and La Banque Postale have also pulled financial support from the project in the last several years.
For investors, this means escalating risks: construction delays, legal battles, potentially stranded assets, and the threat of diminished returns. Continuing to pour capital into this project is not just environmentally irresponsible—it is financially imprudent.
The global energy market is also shifting rapidly. Ongoing trade wars and on-and-off-again tariffs could make it difficult for Rio Grande LNG to meet its Final Investment Decision, the last fundraising hurdle a project like this must clear before beginning a new stage of construction. At the same time, LNG demand is projected to peak before 2030, and an oversupply threatens to depress prices. And the methane emissions from LNG production undermine the climate benefits often touted by proponents.
The Rio Grande LNG expansion is a lose-lose proposition. It jeopardizes the health and environment of frontline communities, threatens local economies and endangered wildlife, and exposes investors to financial and reputational risks. The path forward demands a just transition to clean energy that respects both people and the planet.
Investors in Global Infrastructure Partners and its parent company BlackRock can limit the harms associated with this project. Potential investors with each company should decline to invest in the expansion of the Rio Grande LNG terminal for the sake of local residents, the region’s economy, and returns on investments.
