The North Sea Transition Authority (NSTA) ran a call for evidence between 4 December 2023 and 26 January 2024 on the potential principles, design and timing of a possible future levy on UK carbon storage licences. After reviewing the submissions to the call for evidence, the NSTA has published a response, stating that it intends, unless there are major external developments, to introduce a carbon storage levy in the future, once the CCS industry is on a more self-sustaining footing.
