Sustainability reporting: A comparative study on non-financial reports in the Spanish IBEX35

Abstract

The aim of this TFG is to understand what the future of sustainability reporting looks like and what improvements need to be made. In order to do that, the concept of sustainability reporting is explained, and its history is illustrated. After viewing the Spanish Government’s response to the UN’s 2030 Agenda sustainable development goals, guidelines on how to use two of the most significant and widely used sustainability reporting frameworks -GRI and Integrated Reporting- are detailed. Furthermore, the sustainability reports of two companies of the Spanish IBEX35 -Naturgy and Acciona- of 2021 are analysed and compared. In order for sustainability reporting to be as effective as possible, companies need to set high standards for themselves, adhere to rigorous guidelines and be held accountable by society.
