Thematic Factsheet on Water Scarcity. The world contains an estimated 1 400 million cubic km of water. Only 0.003% of this vast amount, about 45 000 cubic km, are what is called "fresh water resources", i.e. water that can be used for drinking, hygiene, agriculture and industry.

This chapter reviews the recent history of and trends in bottled water, the regulations governing bottled water production and sale, and growing concerns about the costs and implications of bottled water use. It also addresses growing concerns in both industrialised nations where high-quality tap water is readily available and in poorer developing countries where the high cost of bottled water raises questions about equity and access to basic water services for all.

As bottled water use continues to expand around the world, there is growing interest in the environmental, economical, and social implications of that use, including concerns about waste generation, proper use of groundwater, hydrologic effects on local surface and groundwater, economic costs, and more. This paper estimates the energy footprint required for various phases of bottled water production, transportation, and use.
