Corporate finance reporting is based in rigorous, rules-based frameworks yet environmental and social reporting does not seem to have these normalised tools. The sustainable development of the business movement, in terms of increased environmental and social responsibility, will remain marginal as long as policy decisions maintain their direction towards old models of corporate governance that are not based on the key principles of the triple-bottom line, CSR and accountability. This thesis attempts to gauge to what extent Public-Private Partnership performs a transparent and independent source and appraisal of the standards of Governance for Sustainability for selected firms. This investigation is delimited to an Environmental Social Governance metric analysis and comparison of non-financial corporate data disclosure in sustainability reports from the mining and metals industry in the Nordic countries. It has been inferred from the analysis that an extrapolation can be made based on the financial predictions and trend prospecting of LKAB, Boliden Group, Lundin Mining Corporation, and the Swedish Association of Mines, Mineral and Metal Producers for the future growth of both the Nordic mining sector and sustainability reporting. As a result, ‘best-practice’ in reporting procedures could be exported to where demand is highest from pioneering firms with the ‘first-mover’ advantage, to SME’s and other interested firm’s outside of the Nordic countries. It has been identified that using the Global Reporting Initiative reporting framework enhances partnerships in businesses that adopt and use its index to the extent where it becomes integrated into their management chains and business strategies. The more comprehensively a firm discloses its non-financial performances with relation to the GRI framework, the more integrated reports appear to become. The standardisation of the accurate reporting and disclosure used from the GRI G3.1 varies greatly just between three firms in the same sector and region.
