The graph shows development of specific VOC emissions, defined as emissions of VOC per transport unit (passenger-km or tonne-km), by transport mode (road, rail, maritime, inland shipping, air) in 1995 and 2009.
Specific VOC 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 VOC emissions are expressed in grams per passenger-kilometer (for passenger transport) or tonne-kilometer (for freight transport).

If you live far away from school, instead of driving your kids to and from school each day, start a car pooling initiative with the other parents and share the responsibility. It will save you time, petrol and help the environment.
