Drink tap water
Tap water is not only better than its reputation – it is also particularly climate-friendly. According to the Federal Environment Agency, drinking tap water produces less than one percent of the environmental impact of bottled mineral water. And the quality is not necessarily worse than that of mineral water – quite the opposite. And – it is also much cheaper. However, drinking water that has been in the tap for more than four hours should not be used for preparing food and beverages. Drain the water and do the “finger test”: fresh water is noticeably cooler than so-called “stagnant water”.
