In a recent report, researchers from the University of Twente show how the water footprint concept can be applied to businesses or other sorts of organizations. The water footprint of a business is defined as the total volume of freshwater that is used, directly and indirectly, to produce the goods and services delivered by that business. The water footprint of a business consists of two parts: the operational water footprint and the supply-chain water footprint. The water footprint - also when applied to businesses - is a geographically explicit indicator, not only showing volumes of water use and pollution, but also the locations. Business water footprint accounting can serve different purposes: 1. identify the water-related impacts of the business on its social and natural environment; 2. create transparency to shareholders, business clients, consumers and governments; 3. compare water use across business units for benchmarking and target setting; 4. identify and support the development of policy to reduce business risks related to freshwater scarcity.

Freshwater scarcity is increasingly perceived as a global systemic risk. Previous global water scarcity assessments, measuring water scarcity annually, have underestimated experienced water scarcity by failing to capture the seasonal fluctuations in water consumption and availability. We assess blue water scarcity globally at a high spatial resolution on a monthly basis. We find that two-thirds of the global population (4.0 billion people) live under conditions of severe water scarcity at least 1 month of the year. Nearly half of those people live in India and China. Half a billion people in the world face severe water scarcity all year round. Putting caps to water consumption by river basin, increasing water-use efficiencies, and better sharing of the limited freshwater resources will be key in reducing the threat posed by water scarcity on biodiversity and human welfare.

Water is essential for electricity and heat production. This study assesses the consumptive water footprint (WF) of electricity and heat generation per world region in the three main stages of the production chain, i.e. fuel supply, construction and operation. We consider electricity from power plants using coal, lignite, natural gas, oil, uranium or biomass as well as electricity from wind, solar and geothermal energy and hydropower. The global consumptive WF of electricity and heat is estimated to be 378 billion m3 per year. Wind energy (0.2–12 m3 TJe -1 ), solar energy through PV (6–303 m3 TJe -1 ) and geothermal energy (7–759 m3 TJe -1 ) have the smallest WFs, while biomass (50 000–500 000 m3 TJe -1 ) and hydropower (300–850 000 m3 TJe -1 ) have the largest. The WFs of electricity from fossil fuels and nuclear energy range between the extremes. The global weighted-average WF of electricity and heat is 4241 m3 TJe -1 . Europe has the largest WF (22% of the total), followed by China (15%), Latin America (14%), the USA and Canada (12%), and India (9%). Hydropower (49%) and firewood (43%) dominate the global WF. Operations (global average 57%) and fuel supply (43%) contribute the most, while the WF of construction is negligible (0.02%). Electricity production contributes 90% to the total WF, and heat contributes 10%. In 2012, the global WF of electricity and heat was 1.8 times larger than that in 2000. The WF of electricity and heat from firewood increased four times, and the WF of hydropower grew by 23%. The sector's WF can be most effectively reduced by shifting to greater contributions of wind, PV and geothermal energy.
