Why It Matters

GreenMet is strengthening its lobbying firepower as Congress actively advances multiple critical minerals bills addressing domestic production and supply chain security amid China’s stranglehold on global mineral processing.

Bipartisan legislators are pushing legislation like the Critical Minerals Security Act and the Rare Earth Magnet Security Act to reduce foreign dependence.

GreenMet’s policy priorities—particularly implementation details around Inflation Reduction Act tax credits and domestic sourcing requirements—are directly affected by ongoing legislative negotiations.

By the Numbers

GreenMet has maintained consistent lobbying activity since 2021, filing 27 total disclosures focused on critical minerals policy through a hybrid advocacy model.

The organization employs 14 in-house disclosures between July 2023 and November 2025, previously supplemented by external representation from McKeon Group Inc. and Cogent Strategies LLC.

Sabrina Katz joined as registered in-house lobbyist in September 2025, lobbying exclusively for GreenMet since November 2024 with seven disclosures filed. Her expertise centers on critical minerals policy, appearing in 29 of her 37 specific issue entries across defense, manufacturing, energy, and technology sectors.

The Agenda

GreenMet lobbies exclusively on Critical Minerals Policy, focusing on secure domestic supply chains for materials essential to national security and clean energy. Legislative priorities include implementing the Inflation Reduction Act‘s Magnet Production Tax Credit, National Defense Authorization Act provisions, and Defense Production Act applications.

Congress is advancing legislation including the S.429 STRATEGIC Minerals Act, S.789 Critical Minerals Security Act, and H.R.4090 Critical Mineral Dominance Act. Senators Angus King, John Cornyn, and Mark Warner champion bipartisan efforts to counter Chinese dominance.

Broader Context

Congress is moving aggressively on critical minerals policy in 2025. China controls roughly 70% of processing for most strategic minerals, prompting alarm about U.S. supply chain vulnerability. Export controls imposed in 2025 have intensified pressure to build domestic alternatives.

President Trump’s March executive order invoked the Defense Production Act to accelerate mineral production. However, significant uncertainties persist: the critical minerals production tax credit phases out by 2033, creating timeline pressure, while permitting mechanisms remain under negotiation.

Competitive Landscape

GreenMet operates in a crowded policy space. Major players include MP Materials Corp., lobbying on production tax credits for rare earth magnets; the National Mining Association, advocating for streamlined permitting; and Energy Fuels Resources Inc., focusing on uranium and rare earth supply chains.

Multiple committees held high-profile hearings in 2025 examining domestic supply chain resilience. This bipartisan activity creates coalition-building opportunities but intensifies competition for legislative influence and favorable policy language.

The Bottom Line

GreenMet is strengthening internal lobbying capabilities during intense congressional focus on critical minerals policy. The addition of Sabrina Katz as registered in-house lobbyist reflects a strategic shift toward sustained advocacy. With Congress advancing multiple bills and holding hearings on domestic critical mineral supply chains, GreenMet’s expanded team positions it to engage on evolving policy questions around tax credits, permitting timelines, and trade frameworks.
