In 2023, nitrogen oxides emissions in Italy stood at a higher level compared to the projected values for subsequent years. From 2024 onwards, the emissions are forecasted to steadily decline, showing a noticeable year-on-year decrease. Specifically, the reduction in emissions is projected at 7.64% from 2024 to 2025, 8.09% from 2025 to 2026, 8.65% from 2026 to 2027, and 9.29% from 2027 to 2028. Overall, from 2024 to 2028, the compound annual growth rate (CAGR) represents an average decrease in emissions per year.

Future trends to watch for:

Implementation of more stringent environmental regulations might accelerate the reduction of nitrogen oxides emissions.
Advancements in green technologies and renewable energy adoption could further contribute to decreasing emissions levels.
Economic activities and changes in the automotive sector, such as increased use of electric vehicles, are key influencers in emission trends.
