Welcome to the CCS Network Code

The CCS Network Code sets the rules for the safe and reliable transportation and storage of captured carbon dioxide in the UK. Developed by DESNZ and industry, it provides a framework for network access, CO₂ quality and operations. Supporting the growth of carbon capture and storage, it helps deliver a cleaner, lower-carbon future.
