The contest for materiality. What counts as CSR?

Purpose - The paper aims to show that materiality in the EU's non-financial reporting directive (NFRD) is an ambiguous concept, that its meaning is contested and that this contest for materiality is a contest for the meaning of Corporate Social Responsibility (CSR). Thus, the paper shall highlight a new aspect of materiality as a core principle in non-financial reporting. Design/methodology/approach - The paper combines a historical analysis of the EU's CSR policies, an in-depth textual analysis of the EU's 2014 NFRD and associated documents, of non-financial reporting frameworks and exemplary adoptions of the NFRD in national laws. Findings - The paper identifies two conflicting views of materiality in the NFRD. It shows that these “additive” and “cumulative” views correspond to the approaches taken by the Global Reporting Initiative (GRI) and International Integrated Reporting Council (IIRC) frameworks and by different national adoptions of the NFRD. The paper concludes that this contest for materiality is a contest for CSR – focusing either on business risks or impacts, shareholders or stakeholders, the business case or the social case for such a responsibility. Research limitations/implications - The paper is mainly based on an in-depth analysis of the European debate on materiality in non-financial reporting. Some of the paper's descriptive results are thus limited to this particular case. However, the main conceptual findings are backed up by an analysis of internationally established reporting frameworks and scholarly debates on the issue. Practical implications - The paper reveals the practical implications of the contesting “additive” and “cumulative“ understandings of materiality present in the NFRD. The paper thus further underpins the preference for a “double materiality” perspective in the revision of the NFRD and the EC's 2021 CSRD proposal. Originality/value - The paper makes an original contribution in its explication of different understandings of materiality in non-financial reporting and how these eventually represent different, competing perspectives on the nature of the NFRD and of CSR.
