A new bill has been introduced by Sen. Mike Lee from Utah and Rep. August Pflueger from Texas. This legislation aims to stop the United Nations and its affiliates from taxing Americans or their businesses unless it’s part of a treaty approved by the Senate, specifically intended to block a proposed global carbon tax system.
Sen. Lee and Rep. Pflueger are pushing back against ongoing initiatives by UN agencies to establish a global carbon tax, arguing it would place an unfair burden on U.S. taxpayers and threaten national sovereignty. Earlier this year, President Trump managed to persuade the UN to postpone a vote related to this issue. This bill would solidify that success by mandating Senate approval before any international taxes could be imposed on Americans.
The proposed legislation would also prohibit any U.S. financial contributions—whether mandatory or voluntary—used to implement or enforce such a tax. This includes the UN and its various specialized agencies.
A “global carbon tax” is defined in the bill as a tax imposed through a worldwide fuel system, mandating ship operators to either cut emissions or make payments based on their greenhouse gas output. Such taxes could only take effect if explicitly authorized by a Senate-ratified treaty.
Lee highlighted the bill’s significance in an interview, asserting, “Americans will never relinquish sovereignty to United Nations meddlers and their socialist redistribution schemes, particularly this carbon tax nonsense.” He has been vocal about reducing U.S. involvement abroad and advocating for more fiscal responsibility among American allies.
Rep. Pflueger echoed these sentiments on X, stating the bill would prevent “unelected international bureaucrats from dictating to the American people.” He expressed gratitude to Sen. Lee for introducing the measure and expressed optimism about working together to pass it. In a press release, he stated that the legislation would “permanently eliminate the global carbon tax system by cutting off any U.S. funding to UN agencies that attempt to impose taxes on Americans.”
Pflueger also raised concerns about U.S. contributions to the UN, noting that as the largest donor, the U.S. shouldn’t be funding an organization that aims to tax its citizens and weaken its economy.
Likewise, Lee warned that the UN is making efforts to “tax Americans to advance the globalist climate change delusion.” He labeled the United Nations as a “corrupt platform for individuals who oppose our nation” and commended Rep. Pflueger for his leadership in the House. Lee also remarked that the bill aligns with President Trump’s approach of dismantling international frameworks perceived as violating U.S. sovereignty.
The proposed tax-free legislation resonates with broader Republican critiques of the UN’s expanding bureaucracy and spending habits. Recently, U.S. Ambassador to the United Nations Mike Walz and Special Envoy for Reform Jeff Bartos discussed cutting more than $1 billion in internal costs, arguing that the UN has become bloated and strayed from its fundamental mission. Their reforms include reducing personnel expenses, scaling back peacekeeping activities, and aiming to eliminate agencies said to harbor biases against Israel or engage in wasteful practices.
During his confirmation hearing, Walz praised his own background as a Green Beret colonel and policy director for two defense secretaries, labeling him “one of the most qualified candidates for UN ambassador ever.”
