The US approach to antitrust and climate change is conservative and grounded in traditional competition law. There is currently no explicit antitrust exemption or safe harbour for climate-related collaborations, an idea to which even progressive antitrust enforcers have shown resistance.[2] The position differs significantly to the EU and the UK in the ESG space, both at the Federal and State level, with politicians and legal officials now using antitrust as a means by which to put negative pressure on ESG collaborations, particularly on institutional investors and their investments in fossil fuel companies. Although challenges to collaborative climate action initiatives were present pre-Trump's second term, they have intensified recently.
At the Federal level, the Federal Trade Commission and Department of Justice have not signalled any extra flexibility for ESG collaborations. Indeed, the rhetoric emphasises dissatisfaction with the growth of ESG investments and collaborations.
In June 2024, Republicans on the House Judiciary Committee published its “Climate Cartel” report alleging collusion among climate-focused investor groups, activist investors, asset managers, proxy advisors, and blue state pension funds to decarbonize the American economy. The report alleges that the so-called climate cartels were using ESG, net zero initiatives, and other disclosure requirements that amount to a “war on our way of life."[3] Following the publication of this report, the House Judiciary Chairman required over 130 US-based companies, retirement systems and government pension programs to provide further information about "their involvement with the woke ESG cartel Climate Action 100+." The political pressure led to the withdrawal of large investors, including JP Morgan, Goldman Sachs, Wells Fargo, Citi, Bank of America, and Morgan Stanley, throughout 2024 from climate-focused organizations including Climate Action 100+, and the Net Zero Banking Alliance, a sub-group of the Glasgow Financial Alliance for Net Zero. The Alliance encourages companies operating in the financial sector to reduce greenhouse gas emissions by financing the development and scaling of net-zero technologies to replace high-emitting sources. Republican politicians have also denounced net zero initiatives as harmful to the aviation and food & agriculture sectors.
In November 2024, the State of Texas and ten other Republican-led States filed an antitrust lawsuit against institutional asset managers BlackRock, Vanguard, and State Street alleging that they used their large shareholdings in publicly-held coal producers to cause those producers to reduce output, in turn leading to higher energy and electricity prices for US consumers. The proceedings are ongoing: in August 2025 the federal court overseeing the case largely rejected the defendants’ motion to dismiss the states’ claims.
In January 2025, Blackrock separately settled a case brought by the Tennessee Attorney General in 2023—when Blackrock was still a member of Climate Action 100+ and Net Zero Asset Managers - alleging misleading consumer practices around its ESG practices.[4] Blackrock accepted a range of measures as part of its settlement, including casting proxy votes based on independent judgment, maintaining records of rationale for opposing management recommendations on environmental/social matters, disclosing proxy votes and rationale on a more regular basis, removing ESG ratings from US product pages of non-ESG funds, and audits of recordkeeping obligations.[5]
