On 27 September 2026, local time, the United States Supreme Court Justice Samuel Alito announced that he would recuse himself from the case of Borde City, Colorado v. Hydrocarbons Climate Claim, which was due to commence next week, following a reversal of his attitude following allegations by environmental organizations of a conflict of interest in holding hydrocarbon assets. This case was the first to be heard by the Supreme Court in its 2026-2027 session, and the outcome of the judgement will have a direct impact on hundreds of state and local governments in the United States of America with respect to climate claims against the company, which total claims for billions of dollars.
The case was initiated by the city of Bordeaux, Colorado, and various local governments in the state. The plaintiffs, including the large oil and gas companies of Sencor Energy, Canada, and ExxonMobil, United States, claimed that the fossil fuel emissions of the oil and gas companies caused climate change, caused local wildfires, drought, etc., and held the defendant liable for the corresponding damage. The core dispute in the case was whether tort claims at the state level had been prioritized by federal climate law and the principle of constitutional separation of powers, and if the plaintiffs had won, they would have set a precedent for more than a hundred similar local government climate claims in the United States, with a cumulative total of claims exceeding $10 billion. The case, which was scheduled for oral arguments on 5 October 2026, was the first to be heard in a new session of the Supreme Court, after public opinion was generally concerned that the conservative majority of the Supreme Court would continue its tendency in recent years to restrict environmental claims. A few weeks ago, several environmental organizations filed a public complaint with the Supreme Court, stating that Alito had long held large amounts of oil and gas assets since his appointment as Chief Justice in 2006, had a direct interest in the case and did not meet the ethical requirements of judicial evading and asked him to avoid it. Alito did not respond publicly to this, but only on 27 September, through the Registrar of the Supreme Court, sent a brief letter to the parties in the case announcing “the decision not to participate in the case”, without specifying the grounds for disqualification.
Analysis shows that Alito has accumulated up to $2.9 million over the last 20 years of his service in the Supreme Court by holding assets such as shares in oil and gas companies and related funds, which constitute a high degree of overlap with the industry of the defendant in the present case and which is the central basis for the evading charges initiated by environmental organizations. It had been reported earlier that Alito had retained the relevant hydrocarbon assets in the face of recusal pressure, which had suddenly been announced as a reversal of attitudes perceived by the outside world as pressured by public opinion and judicial ethics. It is noteworthy that Alito did not actively avoid other cases involving the oil and gas industry, this time for the first time in his mandate, on charges of conflict of interest, and also to break the expectations of the outside world that he “will not yield to external pressure”. There is currently no evidence of other undisclosed interest links in Alito, nor has the decision to evade been given an additional explanation by the Supreme Court.
The outcome of the judgement in this case will have a direct impact on the interests and follow-up of various subjects. First, the local governments of Colorado, such as the city of Bordeaux, which initiated the claim, were directly affected: if the Supreme Court ultimately ruled in favour of the application of the state tort law, the local government would receive substantial compensation for climate disaster prevention and infrastructure rehabilitation; if the judgement found federal law to be a priority, the local government ' s path to climate claims would be completely blocked. Second, hundreds of state and local governments in the United States are prosecuting oil and gas companies, all of which will use this judgement as a model for determining a follow-up strategy, and the total amount claimed for these cases now amounts to tens of billions of dollars. Thirdly, oil and gas companies would face massive compensation and the ripple effect of more similar litigation if they failed, and would continue to be exempted from climate liability at the state level and maintain the current operating model. Many environmental organizations welcomed Alito ' s decision to recede as a victory for judicial ethics, but also expressed concern that: The final outcome of the current six Conservative Chief Justices of the Supreme Court is likely to be unfavourable to the plaintiff if the remaining Chief Justices, who maintain the tendency of the Judicial Conservatives to consistently restrict environmental claims, do not have similarly disclosed hydrocarbon assets except for the conflict of interest. For its part, the hydrocarbon enterprise did not comment publicly on the disqualification of Alito, but merely expressed confidence that the court would hear the case in accordance with the law.
The oral arguments in this case are scheduled to take place on 5 October 2026 and the parties will meet on the priority of federal law and tort laws of the Länder, and the final judgement of the Supreme Court is expected before the end of the 2026-2027 trial period, i.e. June 2027. In the case of local governments initiating claims, it is important to focus on the preparation of oral arguments, the preparation of responses to possible constitutional decentralization and federal legislative powers raised by the Conservative Chancellor, and the evaluation of follow-up responses to different decisions. In the case of oil and gas companies, there is a need to keep track of the progress of cases, while similar proceedings may be initiated in other jurisdictions. For the public and environmental organizations concerned with climate issues, the decision logic needs to be followed, and if the decision is unfavourable to the plaintiff, subsequent or will push Congress to adopt legislation to clarify the legal basis for the climate claim; if the decision is in favour of the plaintiff, it may trigger more local governments to initiate claims and promote greater climate liability for hydrocarbon companies. On the general public side, the outcome of the case will directly affect the local government ' s sources of financing for disaster prevention and the operating costs of oil and gas enterprises, and may be transmitted to energy prices and public service input levels over the long term.
