Despite the apparent commitment of large Spanish corporations to the SDGs, information about their documented contribution to the 2030 Agenda is still scarce. This article aims to explore this gap by investigating the extent to which Spanish listed companies have been reporting on the SDGs since the approval of the 2030 Agenda. The paper contributes to the country-level analysis of SDG reporting by performing a longitudinal analysis over the 4-year period encompassing 2016 to 2019. It contributes to management science by assessing Corporate Sustainability performance through adherence to the SDGs and testing what the facilitators of SDG reporting have been during the first 4 years since the adoption of the 2030 Agenda. Findings reveal a low commitment of Spanish listed companies to sustainability reporting. Nevertheless, they also uncover how those companies that publish non-financial reports are increasingly reporting on the SDGs. Additionally, there is also a growing tendency among CEOs to mention the SDGs in their letters to stakeholders. Furthermore, a positive link is established between the adoption of GRI reporting standards or being a signatory of the UN Global Compact and SDG reporting. Similarly, those companies that publish Integrated Reports are more likely to consider the SDGs in their disclosures than those that publish Standalone Reports or Annual Reports. Nonetheless, there is a growing tendency to gravitate from producing Integrated Reports to producing Annual Reports. Owing to the breadth of these results and their relevance to academics and practitioners alike, this study can help build future evidence-based accountability literature and policy on the SDGs at the Spanish and European levels.
