In the context of growing transparency requirements, reporting on corporate social responsibility is becoming an unavoidable practice and one of the most effective ways of responding to stakeholder expectations. Smart Kolektiv aims to encourage as many companies in Serbia as possible to recognize the importance of this practice and introduce it into their business, by offering the service of preparing Reports on Sustainable Development according to the GRI methodology (Global Reporting Initiative), as well as by organizing professional training courses on reporting according to this methodology. The importance of reporting on sustainable development has been further enhanced when the EU Non-Financial Reporting Directive, which requires large companies to publish this type of report regularly, entered into force.
