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

Have your water boiler inspected once a year
– to verify whether it isn't poisoning the air in your home or consuming too much energy. Have it replaced once every 15 years – to benefit from the technological advances that render new boilers more energy-efficient.
