The key facts
- ExxonMobil is challenging the Net Zero Industry Act's CO₂ storage obligations through Energy Charter Treaty arbitration
- The EU's target is 50 million tonnes of CO₂ injection capacity per year by 2030; the rules cover 44 large producers
- The EU's target is 50 million tonnes of CO₂ injection capacity per year by 2030; the rules cover 44 major producers
- According to CCS Europe, the EU currently has only 3.54 million tonnes of injection capacity in operation
Arbitration against EU climate rules
Oil and gas giant ExxonMobil is challenging in court European Union rules that require fossil fuel producers to contribute to the creation of carbon storage capacity. According to Euronews, citing an official European Commission document, three companies in the group — ExxonMobil Petroleum & Chemical (Belgium), ExxonMobil Luxembourg and ExxonMobil Netherlands — filed a notice of arbitration under the Energy Charter Treaty (ECT) based on UNCITRAL rules. The document itself does not indicate the filing date, but according to earlier reports, the claim was initiated in July.
The essence of the claims
The companies are challenging provisions of the Net Zero Industry Act (NZIA) that set a Union-level target — CO₂ injection capacity of at least 50 million tonnes per year by 2030 — and require contributions from authorised oil and gas producers. ExxonMobil argues that the stringent climate requirements are unfeasible due to lengthy permitting procedures and high costs. According to the outlet, the giant cites violations of ECT provisions on fair and equitable treatment, non-discrimination and protection of investments from expropriation, and also intends to seek interim measures suspending the obligation to inject CO₂ underground for the affected subsidiaries. The amount of compensation sought and the financial risks for the EU are not disclosed in the document; the Commission declined to comment on ongoing cases and, according to the document, is still analysing the notice.
Who the rules apply to
The NZIA obligations are detailed in two EU acts: one sets the production threshold, the other the required contribution to injection capacity. Companies producing less than 610,000 tonnes of oil equivalent or accounting for less than 5% of EU production are exempt; in total, the rules affect 44 large producers. The logic of the rule is that companies extracting fossil fuels should help build infrastructure for managing emissions, rather than leaving its development solely to public funding or voluntary private investment. The outlet notes that the dispute may test Brussels' ability to make the oil and gas sector pay for the energy transition — especially as the Commission has already postponed the publication of a proposal on rules for CO₂ transport infrastructure, which had been scheduled for the third quarter of the year; the link between the Exxon claim and this delay remains unclear.
How realistic is the target
Brussels presents the 50 million tonne target as a way to accelerate the development of carbon capture and storage (CCS) technologies, which are important for 'hard-to-decarbonise' industries, although the Institute for Energy Economics and Financial Analysis criticises the technology as 'expensive' and 'unproven'. Former MEP and head of CCS Europe Bergur Rasmussen called the target 'ambitious' and 'certainly not guaranteed': according to him, based on the Commission's own data, the EU currently has only 3.54 million tonnes of CO₂ injection capacity in operation, with a projected 27.1 million tonnes — a significant gap for the remaining four years of the decade. Model estimates cited by the outlet suggest that for the 2040 target (a 90% reduction in net emissions), the EU will need around 250 million tonnes of annual storage capacity; the largest projects — Porthos and Aramis in the Netherlands, Greensand and Bifrost in Denmark — are concentrated in the North Sea.
Reaction and context
The environmental organization Bellona warned that the lawsuit could undermine Brussels' efforts to create a viable CCS market, and noted that the case demonstrates how investment protections under the ECT are being used by oil companies against climate legislation. Bellona Europa adviser William Drew said that 'investment arbitration must not become a mechanism through which companies demand compensation for the obligation to accelerate investments that will ultimately become part of their own business models.' ExxonMobil did not respond to Euronews' request. Meanwhile, the Commission continues to promote CCS: in September, Climate Commissioner Wopke Hoekstra unveiled Europe's largest carbon capture facility at the Yara plant in Sluiskil, the Netherlands, designed for 800,000 tonnes of CO₂ per year (a 25% reduction in the plant's emissions), with the gas to be buried under the Norwegian seabed via the Northern Lights project. Norwegian Prime Minister Jonas Gahr Støre called the project proof that CCS works and can be carried out across borders.
