Carbon storage in the North Sea
Carbon storage in the North Sea (also known as carbon sequestration in the North Sea) includes programmes being run by several Northern European countries to capture carbon (in the form of carbon dioxide, CO2), and store it under the North Sea in either old oil and gas workings, or within saline aquifers. Whilst there have been some moves to international co-operation, most of the Carbon Capture and Storage (CCS) programmes are governed by the laws of the country that is running them.
