GRESCO Footprint

This “GRESCO Footprint” is an original, trademarked logo which not only represents GRESCO's Corporate and Social responsibility in reducing its carbon footprint, but also symbolizes GRESCO's total commitment to the well-being of our environment, through the methods in which we provide services, and helping those who we serve to do the same.


Whenever and wherever you see this logo, rest assured, GRESCO has taken all the steps in providing clean and balanced services, with the least amount of negative impact on our environment.
