-NOₓ **total emissions** show a falling trend from 1990 onwards, with emission reductions of 60.3% between 1990 and 2019 and steadily falling emissions in the last years. The Main Driver for NOₓ emissions is **Fuel Combustion (NFR 1.A)** with over 91% of 1990 emissions and a 64% reduction from 1990 to 2019. More than half of the 1990 emissions from **Fuel Combustion (NFR 1.A)** and a similar reduction (-66%) between 1990 and 2019 comes from **Road Transportation (NFR 1.A.3.b)**, mainly due to constantly improving fuels and increasingly stricter regulations resulting in technical improvements. The rest of the 1990 emissions mainly comes from **Energy Industries (NFR 1.A.1)** with a 23% share of 1990 Fuel Combustion (NFR 1.A) emissions and a 61% reduction and to a lesser extend from **Manufacturing Industries and Construction (NFR 1.A.2)** with an 12% share and 71% reduction followed by **Other Sectors (NFR 1.A.4)** with a share of nearly 8% in 1.A and a 42% reduction between 1990 and 2019. For **Manufacturing Industries and Construction (NFR 1.A.2)** some emissions were reassigned to the **Industrial Processes (NRF 2)** starting from the year 2000, leading to lower emissions from the energy sector and a similar rise in the Industrial processes.+NOₓ **total emissions** show a falling trend from 1990 onwards, with emission reductions of 65.6% between 1990 and 2020 and steadily falling emissions in the last years.
