Standardisation of environmental, social and governance (ESG) metrics is a critical foundation for effective corporate disclosure and improved sustainability performance. Our relationship with the GRI has grown since Jonathon’s contribution to elements of the first GRI Sustainability Reporting Guidelines, launched at the World Summit on Sustainable Development (WSSD) in Johannesburg in 2002. More recently, Jonathon convened the GRI / IIRC Corporate Leadership Group on integrated reporting; he serves on the Advisory Group to the GRI Focal Point SA and has been a regulator contributor to GRI Conferences and panel discussions in Amsterdam and Johannesburg. Incite has undertaken various research projects for the GRI, including: assessing the impact of the GRI Framework on reporting and performance in South Africa (2013-2015); contributing to a report on big data and sustainability reporting (2017); evaluating the impact of supply chain reporting in South Africa (2017); and reviewing corporate accountability and action on UN SDG1 on poverty (2018).
