The role of the water footprint in the context of green marketing.

The environmental degradation, because of various factors, such as climate change, human activities, increase of population globally, etc. have brought on pressures on the fresh water supplies that vary on time and space. Consequently, economic, environmental, and social tools have emerged known as footprints, in an effort to examine and measure the needs and consequences of humanity on the Earth's life support systems and take measures towards sustainable development. Furthermore, the constantly worsening environmental conditions have resulted in the cultivation of a green culture among society stakeholders that brought on terms such as green marketing and green products. This paper deals with the water footprint (WF) concept and an effort is performed, to explore through a literature review, in which ways it can contribute to the sustainable development of water use, in the context of green marketing (GM) strategies. The approach of the analysis is based on the discrimination to the following aspects: international scale, national and subnational scale, farmers, business, and consumers, in order to track the affection of each part in water issues. The main findings of the literature review showed that the aforementioned factors are playing a key role in protecting water recourses, by the way they formulate their water use and they are interrelated and interdependent. WFs can be useful in the context of GM, by providing helpful information about direct and indirect water consumption, to every contributor factor in supply chains, to consumers, governments, and water managers.
