 Until 2005, NO<sub>x</sub> emissions followed mileage and fuel consumption. Since 2006, in contrast to nearly unchanged fuel consumption, emissions have decreased due to controlled catalytic-converter use and engine improvements resulting from continual tightening of emissions laws.   Until 2005, NO<sub>x</sub> emissions followed mileage and fuel consumption.

 As for the entire road transport sector, the trends for **sulphur dioxide** (SO<sub>2</sub>) and **ammonia** (NH<sub>3</sub>) exhaust emissions from heavy duty vehicles show charcteristics different from those shown above: Here, the strong dependence on increasing fuel qualities (sulphur content) leads to an cascaded downward trend of SO<sub>2</sub> emissions , influenced only slightly by increases in fuel consumption and mileage. For **ammonia** emissions the increasing use of catalytic converters in gasoline driven cars in the 1990s lead to a steep increase whereas both the technical development of the converters and the ongoing shift from gasoline to diesel cars resulted in decreasing emissions in the following years. As for the entire road transport sector, the trends for **sulphur dioxide** (SO<sub>2</sub>) and **ammonia** (NH<sub>3</sub>) exhaust emissions from heavy duty vehicles show charcteristics different from those shown above: Here, the strong dependence on increasing fuel qualities (sulphur content) leads to an cascaded downward trend of SO<sub>2</sub> emissions , influenced only slightly by increases in fuel consumption and mileage.
