The forecast for Italy's domestic processed output of nitrous oxides (NOx) remains steady at 0.015 metric tons per capita from 2024 to 2028. This consistency suggests no anticipated annual growth or decline in NOx output per capita within the forecast period.

Future trends to watch for include:

Technological advancements in emission reduction, which could further decrease NOx output.
Regulatory changes from the European Union or Italian government that might influence NOx limits or production processes.
Shifts in industrial activity and transportation sectors, as these are major contributors to NOx emissions.
