How savings work
These figures use default emission values. HMRC hasn't published UK values yet, so we use the European Commission's published defaults where they exist and sector averages otherwise. If your suppliers emit less than the default, you're overpaying, and verified supplier data is how you prove it. The difference is tonnage × the gap between your suppliers' emissions and the default × the CBAM rate. Run the calculator with your own figures, or book a call.
