The graph shows development of specific CO2 emissions, defined as emissions of CO2 per transport unit (passenger-km), by passenger transport mode (road, rail, maritime, air) over the period 1995 to 2011.
Data coverage: EEA-32 excluding Iceland and Liechtenstein
Specific CO2 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 CO2 emissions are expressed in grams per passenger-kilometer.

By having aerators and water flow restrictors fitted on your taps, the flow of water will feel stronger, but will consist of less water and more air. Aerated taps can reduce the water flow by 30-40 %.
