Switzerland signs agreement with Denmark on CO2 storage
Switzerland has signed two agreements with Denmark on the permanent storage of Swiss CO2 in Denmark. The agreement follows a similar agreement with Norway, which was signed in June.
Switzerland signed two agreements with Denmark on 3 September that will enable the export and permanent storage of Swiss CO2 in Denmark. Future cooperation in the area of negative emissions technology (NET) and carbon capture and storage (CCS) is also planned, according to a press release. The Federal Council had already approved the two agreements on 27 August 2025.
The partnership with Denmark joins the existing partnership with Norway, which was signed on 17 June 2025 and also enables CO2 storage and bilateral emissions trading. “CO2 storage will also be important for Switzerland on the way to the net-zero target,” said Federal Councillor Albert Rösti in the press release on the agreement with Norway. “This technology complements our existing instruments for decarbonisation.”
The agreements with Denmark and Norway were signed against the backdrop of the Climate and Innovation Act (CIE), which commits Switzerland to reducing its greenhouse gas emissions to net zero by 2050. Net zero is to be achieved primarily by reducing emissions, while emissions that are difficult to avoid, such as those from the cement industry or agriculture, must be offset by CCS or NET technologies. The federal government has been promoting the use of such technologies since 1 January 2025 as part of the CIG.
