2.1 billion people have no access to clean drinking water. This has a huge impact leading to 500.000 deaths per year. Often drinking water is not being cleaned at all. In other cases, clean water is obtained by heating, using wood for fire or charcoal. This impacts the environment by an emission of 400.000.000 tons of CO2 per year and the harvesting of forests with a cut of 2 billion trees. An estimated 1.2 billion people are not boiling their water and 0.9 billion people are boiling water using wood or coal. Furthermore, another 70 million people live as refugees and have an urgent need for water through International Aid Agencies.
