The Kobe Office has been implementing a private power generation system that uses solar energy since April of 1997 in consideration of the environment.
Through the system, 2,757kg of CO2 emissions are reduced annually. (*1)
This is the equivalent to the amount of CO2 absorbed by 197 cedar trees annually. (*2)
(*1). CO2 emissions for one year calculated by multiplying the 118,226kw/h of electricity from the private generation system from April 1997 to December 2014 by the 0.443 CO2 emission coefficient from ENNET(*3) and applying that per year.
(*2). Calculated on the assumption that one 50-year-old cedar tree absorbs approx. 14 kg of CO2 per year (according to "Sink Measures to Prevent Global Warming" by the Ministry of the Environment and the Forestry Agency).
(*3) Due to a change in electric suppliers, figures prior to October 2013 are calculated using the CO2 emission coefficient from Kansai Electric, while figures from October 2013 onward use that of ENNET.
