Use of 100% Clean, Green Electricity at ACG
As part of the ACG Energy strategy to minimize the carbon footprint, ACG’s electricity is supplied by We Energy, a company that provides 100% “green energy”. We Energy is the only provider in Greece that supplies the national electricity system with 100% “green energy” from clean, renewable sources of energy (solar and wind) and provides the corresponding official state and corporate certificates.
In proof of the above, our supplier is providing us with the relevant Guarantee of Origin (GO) issued by DAPEEP S.A. and “green sign”.
