- | == Ammonia and sulphur dioxide == | ||
- | |||
- | As for the entire road transport sector, the trends for **sulphur dioxide** (SO,,2,,) and **ammonia** (NH,,3,,) exhaust emissions from passenger cars show charcteristics very different from those shown above: Here, the strong dependence on increasing fuel qualities (sulphur content) leads to an cascaded downward trend of SO,,2,, 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. | ||

- | |||
- | Compared to submission 2020, specific **activity data** for passenger cars were revised within TREMOD for all years due to re-allocations of consumption shares between the different vehicle types and classes. | ||
