Sustainability and the role of companies in terms of emissions and environmental impact has become increasingly more relevant. In 2014, the EU decided to introduce the NFRD, a directive that makes it mandatory for companies that meet the requirements to report on sustainability. This thesis aims to examine how four large Swedish industrial companies report about sustainability in connection with the introduction of NFRD, looking at the years 2015 (2014), 2017 and 2022 from an environmental viewpoint. Furthermore, the study also intends to investigate how the companies write about their sustainability work, as actual achievements or what they have ambitions to do in the future. In order to carry out the study, a content analysis with elements of both qualitative and quantitative features has been used called the CONI method.
