In concern for natural environment and the quality of the air, NOWA S.A. joined the producers of green energy. Photovoltaic power station whose power is more that 30kWp is working on the roof of our headquarters. Since the beginning of the year, till the end of August installation obtained over 30 MWk clear electric energy. It caused company’s carbon footprint reduction for about 30 tons CO2. Emission of carbon dioxide that we have already succeeded to save can be compared into this one which occurs when standard car with combustion drive circles the equator of the Earth for 2,5 times. This is the quantity approximately similar to what is absorbing by 82 big, mature trees during a year.
