### What is the CBAM cost per tonne of fertilizers in 2026?

About €77.91 per tonne at default values on the Haber-Bosch (Naphtha) route (2.5 tCO2 per tonne plus the default-value mark-up), with 98% of the EU benchmark still allocated free.

### How much does the production route change the CBAM cost?

By 2034 the default-value cost ranges from €149.66 per tonne on the Haber-Bosch (Natural Gas) route to €291 per tonne for the most carbon-intensive route listed.

### How can an exporter lower this cost?

Replace default values with verified actual emissions from the installation: CBAM charges on the embedded emissions declared, and for this sector default values carry a 1% mark-up from 2028.
