In this section, we argue that nitrogen fertilizers are in fact very emission-intensive and that there is limited potential to reduce emission intensity further. For instance, if the carbon price is EUR 50, the extra cost will amount to a 30% increase for the two types of nitrogen fertilizers urea and ammonium nitrate (AN), see Figure 14. The figure does not include free allowances in order to show the "raw impact" of the ETS price.
