Let me begin this short article by pointing out there is an excellent document called the SDG Compass: the guide for business action on the SDGs jointly written by the Global Reporting Initiative (GRI), the UN Global Compact and the World Business Council for Sustainable Development (WBCSD). I strongly encourage you to refer to it for more details on sustainability reporting and the SDGs.
If a sustainability issue was considered material from a GRI standpoint, it should also be material from an SDG standpoint.
Sustainability reporting is not a new thing. Various companies issued social accountability reports as far back as the 1970s. Occasionally they were valiant attempts to describe a company’s impact on the environment and society, but often they were glossy public relations one-offs that, under closer scrutiny, generated more heat than light about the issuer’s performance.
