What is Water Footprint?

The water footprint is a measure that not only indicates the amount of water used in production, but also the type and intended use of water. Water footprint components are generally analysed in three different categories.

The blue water footprint consists of "blue water" sources such as surface and groundwater. It refers to the amount of groundwater and surface water used in the production process.

The green water footprint represents rainwater consumption. The green water footprint, which is calculated by taking into account the amount of evaporation and precipitation, shows how much of the water used in purchased products or daily habits originates from rainwater.

There is also a grey water footprint. This value refers to the water pollution caused by the production of a product and can be considered as the water pollution we cause in daily activities in individual calculations. The grey water footprint should not be perceived as dirty water used in product production, but as clean water used to reduce pollution. In this context, in products with high grey water ratio, the amount of clean water spent to reduce pollution is expressed numerically.
