The graph shows development of specific NOx emissions, defined as emissions of NOx per transport unit (passenger-km or tonne-km), by transport mode (road, rail, maritime, inland shipping, air) in 1995 and 2009.
Specific NOx emissions data for all transport modes are modelled data derived from TREMOVE (http://www.tremove.org/model/index.htm) and TRENDS (http://www.forum.europa.eu.int/Public/irc/dsis/pip/library?l=/environment_trends).
Specific NOx emissions are expressed in grams per passenger-kilometer (for passenger transport) or tonne-kilometer (for freight transport).

Anything you pour down your drain, sink or toilet can eventually end up in our rivers or sea! Never dispose of liquids such as oils, grease, or hazardous liquids – like paint thinners or unused paint – by pouring them down the drain. Instead, collect them in one box and dispose with the rest of your waste. Keep them all in their individual packaging, to avoid possible chemical reactions. This will also make it easier for them to be identified during waste collection. If applicable, take them to your community collection point.
