The figure is showing the variation in green house gas emissions of households with equal income along with variation in contributing factors. Households are grouped in deciles 1-10 (low – high emissions). The 10 % of households with highest GHG emissions (group 10) also has the highest car use, the highest share of single family housing, the most m2 of floor space per person and have the lowest use of green heating (district heating or renewables).
The empirical basis is the Swiss income and expenditure surveys (2000–2003). These four annual surveys include a total of 14,300 households, which reported all their daily purchases for one month. In addition, information on the available durable goods, household characteristics, dwelling, etc. was collected (BFS, 2003). To assess the total GHG emissions of the households functional units were used for describing household demand.

Some 97.5% of water on the Earth is salt water, leaving only 2.5% as fresh water. Of this over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater, with only a small fraction present in rivers, lakes or in the air. Water is a precious resource, use it responsibly and don’t waste it!
