The Global Reporting Initiative’s (GRI) Sustainability Reporting Guidelines, first published in 2000 and most recently updated in 2011 (G3.1), provide a framework for reporting on an organisation’s economic, social and environmental performance.
The Guidelines consist of Principles for defining report content and ensuring the quality of reported information together with information relating to Performance Indicators and other disclosure items, as well as guidance on specific technical topics in reporting.
The disclosures that we make and the performance data reported meet the requirements of the Global Reporting Initiative's application level 'C'. More detail on application levels and a full description of the GRI, its aims, objectives and structure, together with the Guidelines themselves are available at www.globalreporting.org
Details on how our 2012 sustainability reporting is aligned to the reporting elements and the required indicators of Global Reporting Initiative (GRI) can be found in the PDF here.
