Trump Invokes Defense Production Act for Coal

The United States’ invocation of the Defense Production Act to deploy a US$700 million coal production initiative coincides with a broad dismantlement of federal carbon regulations, shifting the North American energy landscape. This pivot creates structural trade asymmetries for Mexico as it faces upcoming USMCA reviews and strict environmental standards under its newly signed EU-Mexico Modernised Global Agreement while trying to reach a 38% clean energy target by 2030. Furthermore, any long-term displacement of natural gas by coal in the U.S. grid threatens to alter pricing and availability for the cross-border pipeline supplies that fuel 65% of Mexico's domestic electricity generation.

President Donald Trump announced on June 4 a nearly US$700 million initiative to support the US coal industry, invoking the 1950 Defense Production Act, a Cold War-era law granting the president broad authority over industries deemed vital to national security, to direct federal funds toward refurbishing coal plants and building new export infrastructure. The decision is the most direct expression yet of an energy policy that has been reshaping the North American energy landscape since January 2025, and one whose implications for Mexico are both immediate and structural.

The funding package provides more than US$425 million to upgrade 13 existing coal-fired power plants across West Virginia, Kentucky, North Carolina, Indiana, Tennessee, Arizona, Arkansas, Oklahoma, North Dakota, and Wisconsin. An additional US$185 million will be used to match corporate funding for coal projects in Alaska, Maryland, and West Virginia, while US$75 million will support construction of the long-proposed West Gateway coal export terminal.

Trump aims to also build two new coal plants and is angling for existing coal plants in four states to remain operational past their retirement dates. The administration claims the initiative will create 14,000 new jobs, with coal firms contributing an additional US$1.7 billion in private investment. "We're into energy that really works," Trump said at the briefing.

The administration has framed coal as both an energy security and national security priority, arguing reliable electricity generation will be critical as the United States works to meet growing power demand from artificial intelligence development and data centers while competing with geopolitical rivals. "Without massive amounts of energy, you can't even play the game," Trump said.

On Feb. 11, 2026, Trump had already signed Executive Order 14387, Strengthening United States National Defense With America's Beautiful Clean Coal Power Generation Fleet, directing the Secretary of War to obtain power purchase agreements with American coal plants to service military facilities and installations, and establishing a policy statement that "coal is essential to our national and economic security." The Defense Production Act invocation on June 4 is the financial implementation of that executive order.

Environmental groups criticized the move directly. "Propping up coal billionaires with taxpayer money is one more way for the Trump administration to put polluters first and put the rest of us at risk," said Kit Kennedy, Managing Director for Power, Natural Resources Defense Council.

The Climate Policy Dismantlement Behind the Announcement

The coal initiative is not a standalone event; it is part of a systematic dismantlement of the US climate regulatory framework that began in January 2025 and has accelerated through 2026. In February 2026, the Trump administration scrapped the EPA's 2009 "endangerment finding,” the legal determination that greenhouse gas emissions threaten human health that served as the foundational basis for all federal climate regulation in the United States. EPA administrator Lee Zeldin said the action would lead to average savings of US$2,400 per household.

The reversal of the endangerment finding removes the legal basis for any EPA-issued greenhouse gas regulation, including clean air standards, vehicle emissions rules, and power plant carbon limits. It effectively means the United States federal government no longer has a statutory obligation to regulate climate-affecting emissions from any source.

The Mexico Dimension: Trade, Gas, and Climate Commitments

For Mexico, the US coal pivot creates three distinct but related challenges. The first is trade and competitiveness. The EU-Mexico Modernised Global Agreement, signed on May 22, includes legally binding commitments on sustainability, labor standards, and environmental protection. Mexico's 2025 energy legislation contains elements that create tension with international disciplines on competition, investment, and non-discriminatory treatment, and with its own climate commitments, at a moment when it is also facing the USMCA review and growing pressure to demonstrate consistency among its energy policy, trade policy, and climate obligations. A US partner that is actively expanding coal production while Mexico pursues 38% clean generation by 2030 creates an asymmetry in the North American clean energy narrative that complicates Mexico's positioning with European partners and multilateral lenders.

The second is natural gas. Washington's coal revival is partly framed as a substitute for natural gas in grid reliability, but US gas exports to Mexico have reached record levels and account for approximately 75% of Mexico's natural gas supply. Mexico's energy interdependence with the United States manifests across hydrocarbon trade, industrial supply chains, and the growing interconnection of energy infrastructure. Any policy that redirects US generation toward coal and away from gas would, over time, alter the supply-demand dynamics of the US gas market, with potential implications for the price and availability of the fuel that generates 65% of Mexico's electricity.

The third is the international climate framework itself. Mexico's Energy Transition Law establishes that the country must achieve 35% of its electricity generation from clean sources, a goal reaffirmed in its Nationally Determined Contribution. In 2026, there remains a significant gap between Mexico's vast renewable energy potential and its actual progress toward meeting its legal clean energy targets. As of 2024, clean energy sources supplied approximately 23.4% of total electricity generation, leaving a gap of more than 14 percentage points to the 38% target by 2030. Mexico is pursuing that target at precisely the moment its largest trading partner is moving in the opposite direction.

The ICJ Advisory Opinion published in 2025 establishes that states have an obligation to employ appropriate regulatory means to prevent significant climate harm, including the adoption of rules, supervisory measures, and effective implementation mechanisms with respect to public and private activities, and that this obligation must be consistent with the best available science and with international commitments assumed. The legal consequences of that opinion for countries that actively expand fossil fuel infrastructure, including through the Defense Production Act, are still being assessed by international law practitioners. But for Mexico, the opinion creates an additional pressure point: its own 2025 energy legislation must demonstrate consistency with climate obligations, at a moment when Washington is demonstrating that such consistency is politically optional.
