For the first time in both the Netherlands and the European Union, an emissions permit has been issued for a project focused on underground CO2 storage.
The Dutch Emissions Authority (NEa) has granted this permit to the Porthos initiative, which plans to store approximately 2.5 million metric tons of CO2 annually in decommissioned natural gas fields beneath the North Sea starting in 2026.
This development represents a significant advancement for Carbon Capture and Storage (CCS) as a key strategy to mitigate industrial CO2 emissions.
Although Porthos itself does not produce significant carbon emissions, it requires an emissions permit to participate in the European Emissions Trading Scheme (EU ETS). The permit is not a simple approval, but rather a set of detailed stipulations that the project must adhere to.
These include mandatory annual reports to the NEa, outlining the volume of CO2 received and stored.
Since companies that supply CO2 to Porthos are not required to buy or surrender emissions allowances for the captured CO2, strict monitoring processes are vital. The permit provides clear guidelines for ensuring this process is carried out effectively.

Before receiving this emissions permit, the Ministry of Economic Affairs and Climate (EZK) had granted storage permits for the Porthos project. Additionally, the State Supervision of Mines (SSM) oversees the project’s compliance with safety and storage regulations.
While Porthos is the first CCS project in both the Netherlands and the EU, the NEa anticipates that other similar initiatives will follow.
One such project is Aramis, which aims to store CO2 in several smaller natural gas fields in the North Sea. Carbon dioxide for this project will be delivered via Porthos using ships and a CO2 terminal.
On a global scale, countries with Emissions Trading Schemes (ETS) are increasingly adopting CCS technology. This is especially true in industries where CO2 emissions are difficult to eliminate, such as cement production.

According to the International Carbon Action Partnership’s (ICAP) 2023 report on Emissions Trading and CCS, only the EU and the UK’s ETS currently encompass the entire CCS process.
The report also notes that the cost of capturing CO2 per ton is often significantly higher than the price of an emissions allowance.
With the granting of this first emissions permit, the Netherlands is taking a crucial step toward large-scale CO2 storage and making progress toward its 2030 climate goals.
