Our suppliers – partners in upholding our social, environmental and ethical values. 

For our company, adherence to social, ecological and ethical standards is hugely important.  We thereby support the goals of the United Nations Global Compact (UNGC). 

We expect our suppliers, as partners and an important part of our value chain, to likewise observe and comply with these standards.

OGE has created a Supplier Code of Conduct to ensure a common understanding of these standards. As a clear commitment to compliance, you agree to the contents of this Code of Conduct and address the issues appropriately in your own supply chains.
