The Greek Sustainability Code adapts to the particularities of the Greek market in terms of the size of the Organizations/Companies by using successive levels. Thus, each Organization that desires to be linked with Sustainable Development and Corporate Responsibility issues can participate in the Greek platform of sustainability, filling in on the different levels of the Greek Sustainability Code depending on the degree of maturity of its internal management and procedures. For this reason, we invite all the Organizations no matter of their size to get linked with the issues of Sustainable Development and Corporate Responsibility through a systematic approach and procedures that each Organization already implements and can vary depending on the legal or regulative context applied.
