PRINCE2 certifiedWhat makes cement different under CBAM
A cement product's embedded emissions are driven by its clinker-to-cement ratio, the kiln fuel mix, and how much of that fuel has been substituted with alternative or waste-derived sources. Two producers making nominally the same cement type can carry meaningfully different figures once those variables are accounted for.
Left unverified, your UK buyer's charge is calculated from a national and sector average default value, a conservative figure that doesn't know your clinker ratio or your kiln's fuel mix. Verified data is what replaces that average with your actual position.
What we ask for
The specific data that actually moves your embedded emissions figure, rather than a generic questionnaire:
- Clinker-to-cement ratio for the specific product exported
- Kiln fuel mix, including any alternative or waste-derived fuels
- Production volumes by cement type (e.g. CEM I, CEM II) for the goods exported to the UK
- Direct process emissions from calcination, separate from combustion emissions
- Any carbon price already applied to production at origin

Common questions
Is calcination counted differently from fuel combustion?
Yes, direct process emissions from the calcination reaction are tracked separately from combustion emissions in a proper verification, since they come from a different part of the process and respond to different levers.
What if our kiln already uses alternative fuels?
That's exactly the kind of detail a default value can't reflect. A lower fossil fuel share in the kiln mix is a real reduction, but it only counts toward your buyer's charge if it's verified and reported, not assumed.
