Set refrigerators slightly warmer

It doesn’t have to be that chilly: Many refrigerators are set far too cold. This doesn’t necessarily keep food fresh for longer – but your carbon footprint suffers: Setting it just one notch warmer can save over 5 KG of CO2 per year! By the way, the ideal temperature in the middle of your refrigerator is 6 to 7 degrees Celsius. For the freezer compartment, -18 degrees is ideal.
