ExxonMobil has launched a confidential legal challenge against European Union rules requiring major oil and gas companies to help develop carbon dioxide storage capacity by 2030, escalating its dispute with Brussels over the bloc’s climate regulations.
The arbitration proceedings concern provisions in the EU’s Net-Zero Industry Act, which places obligations on large oil and gas producers to contribute to the development of carbon storage infrastructure. The Financial Times reported the challenge on Wednesday, citing a memo from the European Commission.
According to the report, the Commission informed the Council of the European Union’s trade policy committee of Exxon’s notice of arbitration last month and is preparing a response.

Exxon said the requirements impose obligations on energy companies without the commercial infrastructure needed to meet them.
“Oil and gas companies are now compelled to provide CO? storage capacity despite the absence of a viable market for carbon capture and transportation, saddling industry with unrealistic timelines and increasing energy costs for all Europeans,” the company said in a statement.
The challenge brings into focus a major dispute over Europe’s energy transition: whether governments should require fossil fuel producers to finance and develop carbon capture infrastructure before a commercially viable market for the technology has emerged.
The dispute has been based on the cost and feasibility of carbon storage.
The Net-Zero Industry Act forms part of the EU’s effort to expand domestic manufacturing and infrastructure for technologies considered important to its climate and industrial objectives. Its carbon storage provisions require oil and gas producers operating in the bloc to contribute to an EU-wide target for developing annual CO? injection capacity by 2030.
The policy is intended to accelerate the availability of geological storage sites needed to capture emissions from industrial facilities and other sources. Carbon capture and storage involves separating carbon dioxide from industrial processes, transporting it, and injecting it into underground geological formations for long-term storage.
However, the technology requires substantial investment across several stages of the supply chain. Capturing emissions at industrial facilities is only one part of the process. Companies also need pipelines or other transportation systems, suitable storage sites, permits, and long-term arrangements for handling the carbon dioxide.
Exxon’s objection centers on the gap between the obligations imposed by the EU and the commercial development of those supporting systems. The company argues that requiring producers to deliver storage capacity on a fixed timetable could increase costs without sufficient demand or infrastructure to support the investment.
The dispute could also influence how the EU distributes responsibility for building carbon capture capacity. Oil and gas companies possess relevant geological, engineering and infrastructure expertise, but the regulatory requirement places a defined obligation on the industry to help deliver the bloc’s storage targets.
The arbitration is part of a broader campaign by Exxon against European policies that it says impose high costs and regulatory burdens on businesses.
Last month, the EU delayed implementation of methane-emissions rules affecting oil and gas imports following pressure from industry groups and governments, including the United States. The delay highlighted the difficulties Brussels faces in enforcing climate requirements across international energy supply chains.
Exxon has also intensified its opposition to a separate EU corporate sustainability law, taking its concerns directly to US President Donald Trump. The company has warned that the regulation could encourage businesses to leave Europe.
The latest challenge adds another dimension to tensions between the energy industry and European policymakers over the pace and cost of decarburization.
Expanding carbon capture and storage capacity is part of the EU’s effort to reduce industrial emissions while maintaining manufacturing activity. However, it has raised a serious question for Exxon: can the regulatory framework create the conditions for investment without transferring infrastructure costs and delivery risks disproportionately to oil and gas producers?
The arbitration could test the legal and commercial limits of the EU’s approach, although the confidential nature of the proceedings means the precise arguments and remedies being sought by Exxon have not been disclosed.
The outcome may have implications beyond the company itself, particularly for other energy producers subject to the same storage-capacity requirements. It also exposes turning ambitious infrastructure targets into commercially workable projects with clear investment incentives, adequate transportation networks and sufficient storage demand as a broader challenge with Europe’s climate strategy.
