We need to be aware of why these reports are necessary and also to know the benefits of the Romanian Sustainability Code (CRS), how we use the CRS platform, what are the CRS criteria needed to prepare the sustainability report, and what performance indicators will be detailed in this report. The preparation of a sustainability report requires specialized professional training in order to train competent experts, as well as additional time dedicated to acquiring these requirements.
