Know the embedded carbon
Every line
carries its carbon.
The tonnes of CO₂e behind every CN line decide the certificate cost. Defaults assume the dirtiest production; prove a supplier’s actual and both the bill and the carbon on the record fall — in step.
Embedded emissions
11.6 t proven below default — on this line alone
The default is the worst case
When you can’t prove it, you pay the dirtiest number.
CBAM’s default values are set to the highest-carbon way each good is made. Without a supplier’s actual on the line, that default fills the blank — inflating the certificate cost and recording carbon against your import that the cleaner producer never emitted.
Direct + indirect
the embedded emissions behind every line — production heat plus the electricity that made it
+22%
the EU default’s typical markup over a proven actual — paid in certificates you didn’t need
€ / tCO₂e
every line priced in money and carbon at once — because the same number decides both
Default vs proven actual
Watch the bill and the carbon fall together.
The same instrument the app runs: hold the EU default, then bring in the supplier’s proven actual. The certificate cost and the embedded tonnes recompute as one — because under CBAM, they are one.

What we mean by carbon
The emissions embedded in the goods. Nothing more, nothing less.
Sustys surfaces the producer-sourced emissions embedded in the CBAM goods you import — the direct emissions of making them and the indirect emissions of the electricity used. That figure goes on the declaration.
- Direct
The emissions of the production process itself — the furnace, the kiln, the reduction. Per tonne of the good, from the installation that made it.
- Indirect
The emissions of the electricity consumed in production — carried for the goods CBAM includes it for, on the producer’s grid or contract.
- × net mass
Intensity per tonne, multiplied by the net mass read from your customs declaration — the embedded total for the line.
How good is the number?
Default, self-reported, verified — and which one you’re billed on.
Carbon data has tiers, and the tier decides the bill. Sustys shows exactly where each line sits and what it would take to climb — so you know which numbers are proven and which are still the default.
EU default
The fallback: the EU’s default value for the route and good — set high, on the dirtiest-production assumption. Pay it when nothing better is on the line.
Self-reported
The supplier’s declared actual for the installation. Lower, specific, and on the record — the moment cleaner production starts to count.
Verified
The actual, confirmed by an accredited verifier’s report — what the definitive period bills on. Sustys carries and displays the figure you source; it doesn’t verify the data itself.
the climb from default is where money and carbon come down
The mechanism, working
Prove a supplier cleaner and you pay less, record less carbon, and send the next order to the producer who earned it. That is CBAM doing what it was built to do — and the embedded number is the signal that makes it happen.
