In the last two decades there has been a growing contribution to environmental and social accounting from the Spanish and Latin American academic community, both in Spanish and in English -the dominant language in the production and dissemination of this type of specialised academic knowledge. In this extensive academic production, the one related to the issuing of sustainability reports has been the most abundant, due, among other aspects, to the accessibility of this type of voluntary information issued by companies. From a position that is generally peripheral to the central core of knowledge production, this research community seems to have tried to integrate itself into the main trends -conventional and alternative -of academic knowledge production and dissemination, marked by a process of homogenisation. However, there are major gaps in knowledge about the impact of this process. In an attempt to make a contribution in this respect, the aim of this paper is to carry out a systematic review of the academic literature on sustainability reporting carried out in Spanish in recent decades. The study reveals a development of academic production dominated by descriptive, positivist works, published by authors with academic affiliation in Spanish universities and in journals mostly outside the accounting field.
