Re: The GRI Report or Explain Campaign (Sustainable Development)
The present day understanding of sustainability in businesses is about the triple bottomline approach: Economically viable, environmentally sound and socially responsible. The GRI report is a means of communicating the performance of an organization in these three dimensions to the stakeholders, some thing similar to the Financial Annual Report meant for the shareholders. Your understanding that Sustainability is related to environmental performance is true to an extent, especially when people equate Sustainable Development to Sustainability. To my knowledge there is a congruence on the understanding of concepts of CSR, Sustainability, Responsible Business etc., now, all referring to various elements (Core and Supplementary indicators) mentioned in GRI reports. You may refer to ISO 26000 too; you will find that the Quality Management System contributes to various aspects of a Responsible (Sustainable) business.
With kind regards,
